ERROR: Could not find a version that satisfies the requirement pymel==1.2.0 (from versions: none)

[marietto2008]

Hello.

I've installed maya 2022 on Ubuntu 20.04. Everything works great except "Pymel2022_64-2022.0-22.0.0.0.x86_64.rpm",

that can't be installed because a python / SSL ? error.

This is the version of python installed as default on Ubuntu 20.04 :

# python3 --version
Python 3.8.10

Below you can see the error that I get. I hope that someone can help me to fix it.

# alien -vc Pymel2022_64-2022.0-22.0.0.0.x86_64.rpm

The real issue here is that the compiled version of Python which ships with Maya installs on Ubuntu is bad, and doesn't link to the proper SSL library, which means that when you try and install pymel (which tries to do a pip install using Maya's python) it doesn't work- that's why you're getting all the SSL errors.

The issue isn't your system's python, it's Maya's.

To solve:

1. Assuming you're following https://knowledge.autodesk.com/support/maya/learn-explore/caas/simplecontent/content/installing-maya... , make sure that the libraries you are sudo ln-s'ing actually exist. That means installing libssl1 explicitly, etc.

2. Compile and install Python3.7 to your Ubuntu install

3. In Maya's lib folder (/usr/autodesk/maya2022/lib/) move the python3.7 folder to python3.7.bak

4. Make a new python3.7 dir, cd into it, and copy your newly compiled Python3.7 libraries here- (sudo cp /usr/local/lib/python3.7/* ./ -R)
5. cd into the new site-packages folder, and copy the .bak's site-packages here (sudo cp -R ../../python3.7.bak/site-packages/* ./)

6. Reinstall pymel, first by canceling the failed install (sudo apt-get remove pymel2022-64) then reinstall using the same method you attempted last time.

Launch maya

Hope this helps, just ran into and solved the same thing.
