I've disabled the subscription manager and registered a few repos, epel and remi, but am unable to install tkinter. Keep getting the error no package available. The only package available is for python 3.4. Was wondering whether anyone else had run into this issue. Not sure how to resolve it there's not a lot of documentation on the RHEL website.
I've also tried installing tcl/tk and yum can't seem to find these packages either. The one package with tcl in it it fails because of dependency problems. No luck with yum groupinstall -y "development tools" either. I'm mostly just trying to install pyautogui which requires tkinter be installed already.
The tkinter package is in the rhel-7-server-optional-rpms repo, though I don't see pyautogui available in RHEL.
Your mileage may vary on whether tkinter is at the right version needed.

Yesterday I uninstalled python 3.7 version by mistake. Then I install python again (this time 3.8 version) and again set up my environment. But I could not start my Django project which has Postgres connection. Actually I cannot install "psycopg2" in my environment. I searched for hours and implement every solutions I get from online but it does not work. Let me tell you what I did so far.
First it said to add Postgres in my PATH so I added C:\Program Files\PostgreSQL\12\bin\ in my PATH.
A new problem then arise with a huge ERROR report with 2 vital Error.
ERROR: Failed building wheel for psycopg2
..........................
Running setup.py install for psycopg2 ... error
I try to upgrade wheel but it says,
Requirement already up-to-date
http://initd.org/psycopg/docs/install.html#install-from-source
I learned from this site that psycopg2 requires python2 version. So I installed python 2.7 also.
I reinstalled PostgreSQL but it does not work.
I deleted my virtual environment and create again but it does not work.
Some says they solve this problem by running pip install psycopg2-binary But it does not work for me.
Please help me to get rid of this. I stuck for hours.
When you asked this question, Python 3.8 had been released very recently so there were not any wheels for Python 3.8 yet.
At the time, my suggestion was to install Python 3.7.X and install the binary wheel with:
pip install psycopg2-binary
Since then, binary wheels have been released for Python 3.8, so the above command should work with Python 3.8.X as well.
I wouldn't try to build from source on Windows if it can be avoided.
Finally, you misunderstood the section of the docs about Python 2. You only need Python 2.7 if you are running Python 2. For Python 3, which you should be using for all new projects, it currently supports Python 3.4 to 3.8.
use:
sudo apt install python3-dev libpq-dev
then try doing:
pip3 install psycopg2
Hope it works for you!!
This problem mainly occurs due to this -- " error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/"
Now to install psycopg2, first you need to install visual studio from Microsoft - https://visualstudio.microsoft.com/visual-cpp-build-tools/
now you need to install the c++ desktop development tool with all its default components selected.
After successful visual studio c++ desktop development kit installation, you can now install psycopg2 successfully in your machine.
I am trying to use pipenv as well as pip and having some issues. I installed pipenv using pip. I installed pipenv using pip. Then I went back and tried to run pip -v and got the following: ImportError: cannot import name main. I have seen this question answered for Linux and Mac, but I cannot use sudo or which commands; I am on Windows 10 using the CMD console. In my scripts folder, I see pip, pip2.7, and pip2. I cannot remember which one was my system pip. I know I need to maybe uninstall and reinstall (I have already tried to upgrade, but of course, without pip running you can't upgrade pip). I don't want to make more of a mess, so I wanted to ask how to resolve this in the CMD console on Windows.
Apparently, when I installed pipenv, it changed the system pip version that I was previously using. For some reason, all of the answers I found were using Linux or Mac, but here is how I resolved it. Simply open your command prompt and type:
$python -m pip uninstall pip
Then, test that you still have your old version installed by typing:
$pip -V
This showed me that I had gone from using pip version 18 back to using version 8.1.1. You should then be able to proceed to other tasks using pip.
I am trying to install pygame over anaconda. My OS is windows 7 64 bit and I downloaded the following files:
pygame-1.9.2a0-cp27-none-win32.whl
pygame-1.9.2a0-cp27-none-win_amd64.whl
prebuilt-x64-pygame-1.9.2-20150907.zip
pygame-1.9.2a0-hg_ea3b3bb8714a.win32-py2.7.msi
pygame-1.9.2a0.win32-py2.7.msi
I get this error after "pip install pygame":
Could not find a version that satisfies the requirement pygame (from versions: ) Some externally hosted files were ignored as access to them may be unreliable (use --allow-external
What am I missing?
Thanks
This worked for me when installing pygame with anaconda. I believe that if you go into the terminal on anaconda and type
Pip install pygame
It installs the latest version of pygame into your environment
I fired up a new Windows google compute engine instance. It's running Windows 2008 R2, service pack 1.
I download and try running the Python .msi installer for version 2.7.9, and it fails with this error:
There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.
I see this error for both the 64-bit and the 32-bit installer.
Has anyone else seen it or know of a work-around?
I reproduced your issue and I found two workarounds:
You can install python 2.7.6 successfully without further action.
If you need python 2.7.9 you can install it deselecting pip from the install menu.
This seems to be related to this answer in another thread although in that case the issue is with version 3.4.
Install python EXCEPT "pip"
Run the python install msi again and select "change"
Select "pip" and install the pip
It would be works...
I think it is a priority problem into the msi package...the package seems to try to install the pip before installing python.exe. So, pip can not be installed...
I'm using Windows 8.1 64-bit. I had 2.7.11 installed and then I tried to install PIP as well via Chocolatey PIP package.
I think my installation had got messed up because I had tried to install Python 3.4 as well as Python 2.
Then I had deleted all the Python 2 and Python 3 files in an attempt to get rid of this.
What worked for me was:
Editing the Environment Variables both, System and User to remove any PYTHONHOME or PYTHONPATH variables
I also deleted the path I had to python2 in the PATH environment variable
Now (as mentioned in Python Issue 22329) after deleting the Environment variables you can go into 'Programs and Features', click on the Python 2.7.11 (64-bit) program and then click 'Repair' - this then worked as I would expect without error.
Now finally I was able to go into 'Programs and Features', click on the Python 2.7.11 (64-bit) program and then click 'Uninstall'.
Edit: I assume this is connected with this PYTHON_HOME answer to a problem with Python 3.4
It seems to be a dependency issue, please try to install "Microsoft Visual C++ 2008 SP1 Redistributable Package (x64)"
I've gone through many threads related to installing mysql-python in a virtualenv, including those specific to users of Percona. None have solved my problem thus far.
With Percona, it is normal to get a long error on pip install MySQL-python in the virtualenv that ultimately says EnvironmentError: mysql_config not found. One method to remedy this is yum install mysql-devel, which I've done. I can actually get mysql-python to install properly outside of the virtualenv via yum.
I'm getting the error in the virtualenv only - it uses Python 2.7.9, wheareas 2.6.6 is what comes with Centos.
Also, with MySQL-python installed via yum it will import to the OS's python interpreter, but will not import into the virtualenv's python interpreter.
To clarify, I only installed mysql-python via yum to see whether or not it would work that way. I would prefer it be by pip, in the environment only.
What am I missing here? As far as I'm aware it should work - considering it will work outside of virtualenv.
Found the solution!
I think it was improper of my to install mysql-devel in the first place, so I went ahead and uninstalled it.
Instead, I used a packaged supplied by Percona - Percona-Server-devel-55
yum install Percona-Server-devel-55 and the problem is solved!
