I installed python 2 by
brew install python
I can localise pip2 but not use it. In the terminal i get an error as:
elenama#s2078:~$ pip2
Traceback (most recent call last):

elenama#s2078:~$ which pip2
/usr/local/bin/pip2
I uninstalled the local python by sudo pip uninstall pip. I also uninstalled python and reinstalled it.
(pip3 works, btw.)
Does anyone have a solution to this problem?
I had the same issue, fixed it by running this
python2 -m pip install --upgrade --force-reinstall pip
Seems to be an issue with current Homebrew Python 2 install. I just installed yesterday and have exactly the same issue (python3 is fine).
I don't have a solution as such, but am able to create a virtualenv with PyCharm, activate that environment, and use pip to install stuff as normal. PyCharm doesn't need virtualenv package to do this.
Since one should use virtualenv (or equivalent) all of the time anyway for real work, it is not so bad a problem that you cannot add packages outside of one. But I think I will file an issue on https://github.com/Homebrew/homebrew-core to see if someone can fix or explain why it is not working.
Also we should all be using Python 3 for everything! This is just one more reminder, as if we needed one.

I am writing because I am having trouble installing Pyomo using pip on Python 3.6 on Mac OSX 10.14
I'm following the installation instructions here.
I can successfully execute the first command:
pip install pyomo
But when I run into trouble when I'm supposed to run the following command to install additional dependencies:
pyomo install-extras
Running this command produces the following error:
Traceback (most recent call last):
File "/usr/local/bin/pyomo", line 11, in <module>
sys.exit(main())
File "/usr/local/lib/python3.6/site-packages/pyomo/scripting/pyomo_main.py", line 82, in main

th.join()

There is a post about this here on Google Groups but no solution yet.
This is a documented issue on the github for Pyomo: https://github.com/Pyomo/pyomo/issues/243
They don't appear to have solved the pip installation of pyomo extras.
However, if you have conda installed - https://docs.conda.io/en/latest/
You should be able to use the terminal commands from:
https://pyomo.readthedocs.io/en/latest/installation.html
run this in terminal after conda has been successfully installed:
conda install -c conda-forge pyomo.extras
I know this isn't pip, but it's at least a workaround until pyomo fixes their documentation.
confirmed working on python 3.x and ubuntu 18.04
I got the problem too (in Ubuntu 18.04).
Try installing it from the git project (https://github.com/Pyomo/pyomo):
In Ubuntu 18.04:
git clone https://github.com/Pyomo/pyomo.git
python3 pyomo/scripts/get_pyomo_extras.py
Use the corresponding commands for Mac OSX (I had never used it).
I hope that it works for you.
I have a problem using ROS Kinetic in Ubuntu 16.04.
It was working normally but suddenly rosdep dissapeared while I was trying to configure the Turtlebot Simulator and the AR Drone Autonomy Package.
When I type sudo rosdep init it shows the next error
Traceback (most recent call last):
File "/usr/local/bin/rosdep", line 4, in <module>
__import__('pkg_resources').run_script('rosdep==0.11.5', 'rosdep')
File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 739,in run_script
File "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 1486, in run_script
pkg_resources.ResolutionError: No script named 'rosdep'
I tried to install rosdep manually with sudo apt-get install python-rosdep but it shows that python-rosdep is already the newest version (0.11.5-1)
I tried uninstalling ROS using sudo apt-get purge ros-* and sudo apt-get autoremove and installing it again.
And also reinstalling it using sudo apt-get install --reinstall ros-kinetic-desktop-full but no working.
I am following the instructions of the official
site .
Any idea of what can I do to solve this? Thanks
rosdep is actually completely independent from all the ros-** packages because it is used to install them, which is why reinstalling those packages didn't help.
My best guess would be that you used pip in addition to apt for something with rosdep, and now have 1.5 or 3 different versions of rosdep. Please try removing rosdep installed using apt completely:
apt-get purge python-rosdep and make sure that there are no errors when removing the package. If there are any, post them as comment here. Then, check all python import paths for a folder named rosdep, and remove them. You can find out your python import paths by running the following python script:
import sys
print sys.path
Then, you type which rosdep. If there is a rosdep binary anywhere, remove it. Then you can reinstall rosdep: sudo apt install python-rosdep.
I am attempting to install PyMC using pip install pymc. I believe this command should install PyMC 2.3.6.
PyMC has a few dependencies, which I have in my PATH. I am running OSX 10.11.2 and my PATH includes Python 2.7.13, NumPy 1.12.0, Matplotlib 2.0.0, gcc, and gfortran.
Python (including pip) was installed using Homebrew. NumPy and Matplotlib were installed using pip. The gfortran compiler was downloaded and installed from the GCC Wiki for the purpose of this installation.
Executing pip install pymc yielded lots of output including the following lines.

As suggested in these two pip installation threads about egg_info errors [1, 2], I ran pip install —upgrade setuptools and pip install ez_setup. Once these items were installed I ran into the same types of errors pasted above.
As noted in other package installation threads, I am willing to use conda to install PyMC if I cannot resolve these issues. However, I'd like to investigate this installation issue first.
Would anyone happen to know what my issue is here? Might there be some steps I can take to successfully install PyMC using pip?
I had the same problem. I don't understand the root cause, but I fixed it by downgrading numpy to version 1.10.1: pip install numpy==1.10.1
I also met this problem while trying to install pymc from pip or source code, but I found a solution that might be useful.
The reason that causes the problem might be the file setup.py, in which the script check the compile env. I didn't read the code very carefully, but in the function build_ext() I think the codes first check whether some compile environments have already been installed into OS. If installed, the script will use them as defaults; if not, use ones in somewhere else (the comment says 'from netlib sources').
I infer the problem is caused by the compile environments that have already been installed in the OS, so I modify the file setup.py to skip this part of codes, and let the script use the netlib source. Then I run sudo python setup.py install. There are some error and warning messages, but the folder 'pymc' emerges in python library, and some simple test codes run successfully.
I'm trying to get a django site up on bluehost. I already have one running using python2.7, but for this new project I am using python3.5. I've pretty much tried to set everything up the same way that I did before, except using python3. When trying to install flup:
pip3 install flup
but I am getting an error:
Collecting flup

Complete output from command python setup.py egg_info:

Command "python setup.py egg_info" failed with error code 1 in /var/tmp/pip-build-mzc6swh8/flup
I am guessing that this instance is flup is seeing my python2 version of flup or something and throwing an error. Any ideas on how to solve this?
Also, I've seen this, but that's not the issue I am having.
The answer is here:
https://stackoverflow.com/a/27703117/1378264
(install flup6 instead flup because flup does not work with python3)
Use flipflop instead
pip3 install --upgrade flipflop
flipflop is what did the trick for me.
flup-py3 has an unresolved issue which has been standing open for a couple of years now.
Do not forget to edit the import line in your .fcgi script to reflect this change towards using flipflop.
I need to use this plugin plugin in my app, but i have no idea about how to install and use it. So far, I have found this fork of the mentioned plugin that adds a setup.py script. After issuing the commands python setup.py build and python setup.py install, I added 'django_inlinecss' to my INSTALLED_APPS setting, but still get the following error:
.
. (rest of the traceback)
.
File "/usr/local/lib/python2.7/dist-packages/django/utils/importlib.py", line 35, in import_module
__import__(name)
ImportError: No module named django_inlinecss
How can I install this plugin and use it properly?
Sorry about the inconvenience - I didn't realize people had really started to use that library! (It's great to have people actually finding it useful by the way!)
Anyway, I've released it on Pypi, so you should now be able to just do a:
$ pip install django-inlinecss
If you have issues please open a ticket over at:
https://github.com/roverdotcom/django-inlinecss
I had the same problem, so I forked django-inlinecss original repostory and fixed the problem.
You can use
pip install git+https://github.com/fjsj/django-inlinecss.git#18f2f8e5b5453f067dff0d6c0c2ae3066e56d554
to install it successfully. It was missing a packages=find_packages(), line in stevejalim's setup.py.
