Virtualenv: No module named 'virtualenv.seed.via_app_data'

Issue

On calling virtualenv test i expect it to create a folder named test with all the virtual environment files in there. The observed behaviour is just the following message with no folder test created:
ModuleNotFoundError: No module named 'virtualenv.seed.via_app_data'

Environment

Provide at least:

OS: Ubuntu 20.04
pip list of the host python where virtualenv is installed:

Our boxes appeared to have both debian versions and pip versions installed.. but even after removing the debian version I couldn't get this to work with the latest (20.0.25) pip version. Everything works with...

sudo pip3 install virtualenv==20.0.23

How did you install virtualenv?

gaborbernat on 24 Jun 2020

sudo apt install python3-virtualenv

i already removed and reinstalled it multiple times with no success.

make-ing on 24 Jun 2020

In this case, the issue isn't with virtualenv the project, but Debians repackaging, so please report your issue under http://bugs.debian.org/cgi-bin/pkgreport.cgi?package=python3-virtualenv

In the meantime, you might use our alternative installation methods to get the non debian version https://virtualenv.pypa.io/en/latest/installation.html#installation

gaborbernat on 24 Jun 2020

@kitterma FYI

gaborbernat on 24 Jun 2020

Thank you very much for the very fast response... i will try the alternate install method.

UPDATE:
I removed it with apt remove and tried the installation method with pip which said it was already installed. After trying to reinstall with --force-reinstall everything is working fine.

make-ing on 24 Jun 2020

Thanks. The last Ubuntu release happened at a point where I was still working through some issues in Debian. I don't work on Ubuntu directly, so I'm not sure on the details.

I'm glad reinstalling resolved your issue.

kitterma on 24 Jun 2020

@kitterma note that he reinstalled it with pip, note apt-get... so per se this is still broken at Debian level.

gaborbernat on 24 Jun 2020

Thanks. Missed that. I haven't tested on Ubuntu. It works on Debian though.

kitterma on 24 Jun 2020

Does it, what's your virtualenv version? Note virtualenv 20.0.24 refactored the internal implementation detail module seed... so Debian patching is likely broken unless you fixed that since then.

gaborbernat on 24 Jun 2020

I'll check and make sure once I'm in front of a computer again.

kitterma on 24 Jun 2020

Note virtualenv 20.0.24 refactored the internal implementation detail module seed... so Debian patching is likely broken unless you fixed that since then.

Ubuntu 20.04 has version 20.0.17.

The traceback in the issue points at /home/florian/.local/lib/python3.8/site-packages/virtualenv/ so I'm guessing @make-ing had installed 2.0.24 through pip, and that install was somehow broken. This would be before the Ubuntu virtualenv module in sys.path.

sudo pip3 install virtualenv==20.0.23

rowanseymour on 24 Jun 2020

@gaborbernat I haven't packaged 2.0.24 yet, so anything 2.0.24 in Debian or Ubuntu isn't distro packaging related.

kitterma on 24 Jun 2020

So it's as detailed above just users installing virtualenv both via pip and via apt at the same time and conflict between the repositories trigger this. Any way Debian can raise some error in such cases?

gaborbernat on 24 Jun 2020

I hit this issue on ubuntu bionic as well when installing virtualenv with pip (not apt-get). Downgrading to 20.0.23 also solved it in my case.

keith on 9 Jul 2020

I can also confirm that downgrading version to 20.0.23 solves the problem for focal fossa.

ycd on 14 Jul 2020

I have the same problem. How to make the downgrade?

ruannyury on 15 Jul 2020

@ruannyury pip uninstall virtualenv then pip install virtualenv==20.0.23

ycd on 15 Jul 2020

In all these cases downgrading it's not the actual solution. It might fix the issue for now but you'll get an outdated version of the software. You'd better find out why you have two versions installed in parallel and remove both, and then install the new one.

gaborbernat on 15 Jul 2020

How to find out? forgiveness for the inconvenience

ruannyury on 15 Jul 2020

My OS is Manjaro 20.0.3

ruannyury on 15 Jul 2020

pip uninstall virtualenv, pip uninstall virtualenv? (Do it twice)

gaborbernat on 15 Jul 2020

In the second time:

Should I use the sudo?
