Uninstalling Ipython-0.12 on OS X - uninstallation

I have upgraded from OS 10.6 to 10.8, and done a full new installation of Xcode Command Line Tools, MacPorts, and Pip. I have used Pip to install Ipython-0.13, which runs when I open it from its own directory; but when I type ipython at the command line, only an old version of Ipython-0.12 opens from the /Applications directory. Manually deleting that old version and then typing ipython brings an error message
python: can't open file '/Applications/ipython-0.12/ipython.py': [Errno 2] No such file or directory
and no uninstall/remove commands to Pip or MacPorts result in an uninstall of this old version (naturally, since the old version was not installed with Pip or MacPorts).
What do I need to do so that ipython-0.12 is gone and forgotten, and ipython at the command line starts the most current version? Where is python looking to find the current version of Ipython, and how do I update that manually?

It was pilot error. My .bash_profile contained an alias assigning ipython-0.12 to the name ipython. When I removed it and rebooted, all was well.

Unable to find pygame.image.load [duplicate]

I have installed python 3.3.2 and pygame 1.9.2a0. Whenever I try to import pygame by typing:
import pygame
I get following error message :
Python 3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 00:03:43) [MSC v.1600 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import pygame
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
import pygame
ImportError: No module named 'pygame'

I went through some of the questions related to this error but none of the solution helped.
I have 64 bit machine with Win7 OS
go to python/scripts folder, open a command window to this path, type the
following:
C:\python34\scripts> python -m pip install pygame
To test it, open python IDE and type
import pygame
print (pygame.ver)
It worked for me...
Here are instructions for users with the newer Python 3.5 (Google brought me here, I suspect other 3.5 users might end up here as well):
I just successfully installed Pygame 1.9.2a0-cp35 on Windows and it runs with Python 3.5.1.
Install Python, and remember the install location
Go here and download pygame-1.9.2a0-cp35-none-win32.whl
Move the downloaded .whl file to your python35/Scripts directory
Open a command prompt in the Scripts directory (Shift-Right click in the directory > Open a command window here)
Enter the command:
pip3 install pygame-1.9.2a0-cp35-none-win32.whl
If you get an error in the last step, try:
python -m pip install pygame-1.9.2a0-cp35-none-win32.whl
And that should do it. Tested as working on Windows 10 64bit.
I was trying to figure this out for at least an hour. And you're right the problem is that the installation files are all for 32 bit.
Luckily I found a link to the 64 pygame download! Here it is: http://www.lfd.uci.edu/~gohlke/pythonlibs/#pygame
Just pick the corresponding version according to your python version and it should work like magic. The installation feature will bring you to a bright-blue screen as the installation (at this point you know that the installation is correct for you.
Then go into the Python IDLE and type "import pygame" and you should not get any more errors.
Props go to #yuvi who shared the link with StackOverflow.
open the folder where your python is installed
open scripts folder
type cmd in the address bar. It opens a command prompt window in that location
type pip install pygame and press enter
it should download and install pygame module
now run your code. It works fine :-)
I had the same problem and discovered that Pygame doesn't work for Python3 at least on the Mac OS, but I also have Tython2 installed in my computer as you probably do too, so when I use Pygame, I switch the path so that it uses python2 instead of python3. I use Sublime Text as my text editor so I just go to
Tools > Build Systems > New Build System and enter the following:
{
"cmd": ["/usr/local/bin/python", "-u", "$file"],
}
instead of
{
"cmd": ["/usr/local/bin/python3", "-u", "$file"],
}
in my case. And when I'm not using pygame, I simply change the path back so that I can use Python3.
The current PyGame release, 1.9.6 doesn't support Python 3.9. I fyou don't want to wait for PyGame 2.0, you have to use Python 3.8. Alternatively, you can install a developer version by explicitly specifying the version (2.0.0.dev20 is the latest release at the time of writing):
pip install pygame==2.0.0.dev20
or try to install a pre-release version by enabling the --pre option:
pip install pygame --pre
Resolved !
Here is an example
C:\Users\user\AppData\Local\Programs\Python\Python36-32\Scripts>pip install pygame
try this in your command prompt:
python -m pip install pygame
I was getting the same error. It is because your version of Pygame is not compatible with your version of Python or Pydev. Go to this link and get the proper version of Pygame for your current version of Python. Ctrl F to find it faster or click on the word python in blue. up at the top. While you instal Pygame it should find the Python path by itself. At least mind did any ways. I run Pygame through Eclipse with Python 3.4.

Since no answer stated this:
Make sure that, if you are using a virtual environment, you have activated it before trying to run the program.
If you don't really know if you are using a virtual environment or not, check with the other contributors of the project. Or maybe try to find a file with the name activate like this: find . -name activate.
Install and download pygame .whl file.
Move .whl file to your python35/Scripts
Go to cmd
Change directory to python scripts
Type:
pip install pygame
Here is an example:
C:\Users\user\AppData\Local\Programs\Python\Python36-32\Scripts>pip install pygame
I just encountered the same problem and found that I am having multiple interpreters of the different versions installed in my system and pygame got installed in one of them when I installed it using command but in my IDE another interpreter was selected so this messed up my system, try to see if you are also having the same situation.
Just use this command in the terminal python3 -m pip install -U pygame --user
I am a quite newbie to python and I was having same issue. (windows x64 os)
I have solved, doing below steps
I removed python (x64 version) and pygame
I have downloaded and installed python 2.6.6 x86: https://www.python.org/ftp/python/2.6.6/python-2.6.6.msi
I have downloaded and installed pygame (when installing, I have chosen the directory that I installed python): http://pygame.org/ftp/pygame-1.9.1.win32-py2.6.msi
Works well :)
You don't need 64 bit Python on Win64 system, just install the 32bit versions of both Python and Pygame and they will work just fine (and there is a ton more modules for them anyways).
I’m using the PyCharm IDE. I could get Pygame to work with IDLE but not with PyCharm. This video helped me install Pygame through PyCharm.
https://youtu.be/HJ9bTO5yYw0
(It seems that PyCharm only recognizes a package; if you use its GUI.)
However, there were a few slight differences for me; because I’m using Windows instead of a Mac.
My “preferences” menu is found in: File->Settings…
Then, in the next screen, I expanded my project menu, and clicked Project Interpreter. Then I clicked the green plus icon to the right to get to the Available Packages screen.
I ran into the error a few days ago! Thankfully, I found the answer.
You see, the problem is that pygame comes in a .whl (wheel) file/package. So, as a result, you have to pip install it.
Pip installing is a very tricky process, so please be careful. The steps are:-
Step1. Go to C:/Python (whatever version you are using)/Scripts. Scroll down. If you see a file named pip.exe, then that means that you are in the right folder. Copy the path.
Step2. In your computer, search for Environment Variables. You should see an option labeled 'Edit the System Environment Variables'. Click on it.
Step3. There, you should see a dialogue box appear. Click 'Environment Variables'. Click on 'Path'. Then, click 'New'. Paste the path that you copies earlier.
Step4. Click 'Ok'.
Step5. Shift + Right Click wherever your pygame is installed. Select 'Open Command Window Here' from the dropdown menu. Type in 'pip install py' then click tab and the full file name should fill in. Then, press Enter, and you're ready to go! Now you shouldn't get the error again!!!
First execute python3 then type the command import pygame,now you can see the output
For this you have to install pygame package from the cmd (on Windows) or from terminal (on mac). Just type pip install pygame
.If it doesn't work for you, then try using this statement pip3 install pygame .
If it is still showing an error then you don't have pip installed on your device and try installing pip first.
make sure if you are on windows that your library directory is added to path
This may happen when pygame didn't installed, install the pygame first
pip
pip install pygame
if dont work update the PIP by goto python install folder and type
python -m pip install --upgrade pip
hope it work
Try this solution:
Type in to cmd (Windows):
C:\Users\'Your name'> pip install -U pygame
You should remove python -m, py -m, python3 -m before the pip
Also remove --user behind it.
It will said:
C:\Users\viait>pip install -U pygame
Defaulting to user installation because normal site-packages is not writeable

Hello from the pygame community. https://www.pygame.org/contribute.html
(IDE example)
import pygame
You can do this without any errors.
You could use
pip install pygame
but if you use IDE like PyCharm, then you could just either install it from Python Packages or use right click at the package name then left click on Show Context Actions then left click on Install package pygame
(Personally, I recommended using Python Packages for the package installing because it has documentation with it)
You gotta use Pycharm and install it in Terminal using pip install pygame and also after that enter Pycharm and hover on pygame in the "Import pygame" and in Pycharm it will tell you to download that and you can easily download it and enjoy your result
I was having the same trouble and I did
pip install pygame
and that worked for me!

Installing Homebrew Python and linking

I need to use the Homebrew version of Python rather than the system version of Python. I have a clean install of macOS Sierra (10.12.5).
I first installed homebrew and then updated ~/.bash_profile using nano ~/.bash_profile.
Then I added this into the file:
# Homebrew
export PATH=/usr/local/bin:$PATH
Then, I needed to manually source the ~/.bash_profile file to ensure the changes have been reloaded using source ~/.bash_profile.
I installed python using brew install python and tried to link using brew linkapps python
The output was this:
Warning: Already linked: /usr/local/Cellar/python/2.7.13_1
To relink: brew unlink python && brew link python
Gautams-Air:~ gautam$ which python
/usr/bin/python
Gautams-Air:~ gautam$ python -V
Python 2.7.10
Gautams-Air:~ gautam$ brew linkapps python
Warning: brew linkapps has been deprecated and will eventually be removed!
Unfortunately brew linkapps cannot behave nicely with e.g. Spotlight using
either aliases or symlinks and Homebrew formulae do not build "proper" .app
bundles that can be relocated. Instead, please consider using brew cask and
migrate formulae using .app's to casks.
Linking: /usr/local/opt/python/IDLE.app
Linking: /usr/local/opt/python/Python Launcher.app
Linked 2 apps to /Applications`
Using which python the output was:
/usr/bin/python
It should have been: /usr/local/bin/python
I also tried using: brew unlink python && brew link python
Also using python -V it shows Python 2.7.10 although the current version in Homebrew is Python 2.7.13
How do I use the Homebrew version of Python instead of the system version of Python? - How do I do the linking?
USING:
macOS Sierra (10.12.5)
Due to a recent change in the Homebrew formula for python2 starting with version 2.7.13_1, Homebrew no longer creates a symlink for python to the Homebrew version.
Instead, it only installs and symlinks python2. You will need to take an additional step to use it instead of the system version of Python.
See the "Caveats" section in this package's info. Below is an example, but note that the actual PATH to export is generated and may be different on your machine.
$ brew info python2
... snip ...
=> Caveats
This formula installs a python2 executable to /usr/local/bin.
If you wish to have this formula's python executable in your PATH then add
the following to ~/.bash_profile:
export PATH="<... some path ...>:$PATH"
... snip ...
Edit: Homebrew talked more about this change in their recent release notes.

How to use -pip- to install packages that can work with Anaconda?

I am trying to install some additional packages that do not come with Anaconda. All of these packages can be installed using pip install PackageName. However, when I type this command at the Anaconda Command Prompt, I get the following error:
Fatal error in launcher: Unable to create process using '"C:\Python27\python.exe
" "C:\python27\scripts\pip.exe" install MechanicalSoup'
I also tried to run the command from the python interpreter after import pip but that also did not work (I got a SyntaxError: invalid syntax).
I am a noob and understand that this might be a very basic question so thanks for your help in advance!
PS: I am using Windows 7, 64 bit, conda version: 3.7.1 and python version: 2.7.6.
When installing anaconda, you are asked if you want to include the installed python to your system PATH variable. Make sure you have it in your PATH. If everything is set up correct, you can run pip from your regular command prompt aswell.
Using #heinzchr's and #mmann's suggestions I was able to piece together the problem. I already had a version of Python 2.7 saved at C:\Python27 and I had to remove this from the Path (My Computer's properties> Advanced system settings> System variables> Path). I can now use pip install from the command line.
There is a way around the use of pip
From the anaconda terminal window you can run:
conda install PackageName
Because MechanicalSoup isn't in one of anaconda's package channels you will have to do a bit of editing
See instructions near the bottom on their blog
For those looking for Python packages not added to current channels in anaconda, try https://conda-forge.org/ For example, if you want to install MechanicalSoup you'll find it at https://anaconda.org/conda-forge/mechanicalsoup and use the -c option to tell conda the channel to use:
conda install -c conda-forge mechanicalsoup

Windows 7 virtualenv envl AssertionError and OSError

AssertionError: C:\Python27\lib\site-packages\virtualenv-1.11-py2.7.egg\EGG-INFO\PKG-INFO is not a subpath of C:\Python27\lib\site-packages\virtualenv-1.11-py2.7.egg\virtualenv_support\setuptools-2.0.2-py2.py3-none-any.whl\
OSError: Command D:\myproject2\envl\Scripts\python.exe -c "import sys, pip; pip...ll\"] + sys.argv[1:])" setuptools pip failed with error code 1
How can I fix the AssertionError and OSError?
I tried "activate", but it doesn't work.
I know activate.bat file didn't exist...
I think it is because of these errors.
I just ran into this today. Although not possibly the best answer, here's what I did:
Completely uninstalled all previous Python versions. (I had 64bit versions of both 2.7 and 3.2 already installed, plus a 32bit version of 2.7)
Removed any remaining files in the python install path(s).
Restarted. (Just in case)
Re-installed python.
Followed the non-chocolatey version of https://zignar.net/2012/06/17/install-python-on-windows/ exactly. (aka I didn't install pip via easy_install, but instead downloaded the get-pip.py file as explained in the guide)
Run which virtualenv to check that virtualenv is installed and being pulled from the correct location. (If not, add the path to you python install to you PATH environment variable, removing any other python paths)
Now when I try virtualenv --no-site-packages <packagename>, it works!

How to Install Matplotlib Basemap Module on Windows 7 with WinPython (or any Python stack install)?

I've found that the Basemap (module for matplotlib and Python) binary installer for Windows cannot detect Python on the system when Python is installed as part of a stack install, like Anaconda or WinPython. The installer exits, rather than allow you to point to the directory of installation.
I have to therefore install via source. However, I don't know the method to do this. The Readme.txt and install instructions don't seem to help. They simply instruct to "install geos-3.3.3 first" - well, how exactly? I don't see a setup.py in that directory.
Any help would be great. (Python 2.7, Win 7, 64b)
I use windows. And my installation failed with official guidance, too.
Finally I installed Basemap using the following method. Although I am not sure if it will go right for you, I just offer mine.
First of all, you must have pip in your computer. (It is much easier
to install, compared with Basemap and other things. And it can be
used to install many useful packages.)
Then go this great link: http://www.lfd.uci.edu/~gohlke/pythonlibs/
And download the file named "basemap‑1.1.0‑cp27‑cp27m‑win32.whl".
Move the .whl file to directory "C:\Python27". (Maybe you
installed your python in different disk, then change it
accordingly.)
Open terminal. (Use cmd or Git Bash or something else.)
Use command:
pip install basemap‑1.1.0‑cp27‑cp27m‑win32.whl
The following worked for me using Python 3.10.1.
Setup environment using terminal in Visual Studio Code (https://code.visualstudio.com/docs/python/python-tutorial):
py -3 -m venv .venv
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope Process
.venv\scripts\activate
Install basemap using pip:
pip install matplotlib
pip install basemap-data
pip install basemap-data-hires
pip install basemap
Create file with code from: https://matplotlib.org/basemap/users/examples.html
Remember to select the correct interpreter (In VSCode use Ctrl+Shift+P to select interpreter).
That's it.
