virtualenv Problem with Debian 11

[4920441]

Hi,

don't know what's the root cause of the

virtualenv setup AttributeError: module 'virtualenv.create.via_global_ref.builtin.cpython.mac_os' has no attribute 'CPython2macOsFramework'

... any Ideas?

It looks like virtualenv simply fails to setup.

AttributeError: module 'virtualenv.create.via_global_ref.builtin.cpython.mac_os' has no attribute 'CPython2macOsFramework'

I honestly have no idea why it would setup a MacOs framework. I just use this tool to leverage a python isolated environment to build dependencies.

After a quick search I found this. It looks like you may have a different python virtual environment installed causing conflict.

I'll start by trying to reproduce this problem and see what can be done.

I just performed a complete build on a vanilla Debian 11.11 without issues. I did manage to reproduce the issue after installing virtualenv from the apt repository.

I should be able to simply check if virtualenv is already installed before downloading it.

The fix should be available soon.

You can pull the latest changes and give it a shot.

cool, thank you very much. Just wanted to add the information, that I double checked it on another installation of the same os and the same happens:-) But yes, virtualenv is also installed there as a debian package.

I'll try it tonight!

Thanks a lot!
