Cannot run tests on an Ubuntu 20.04.3 AWS server

[alicezou]

Hi, I am trying to run tests on Ubuntu 20.04.3(an AWS server).

Problem

I am able to run

pip install -e .
pip install -e .[test]

in beets/ directory

However, when I run tox, it failes.

Hmm; it looks like the problem is coming from running Sphinx to build the manpage that goes in the source distribution. I'm guessing that there is a partial Sphinx installation from the Debian packages (because Debian likes to "atomize" packages to install components separately).

Maybe try pip install -U sphinx to get the latest version from PyPI?

[alicezou]

Yes, it works (with some more errors that can be found on stackoverflow.)
BTW, can you check my pull request at #4327 ?
The integration tests as well as the local tests on AWS have passed.

[sampsyo]

Great! Leaving some notes here about how you fixed the problem might help other people in the future. 😃

It's in my queue (and hopefully that of other beets contributors as well).

[alicezou]

Sure 😃
I got this error

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

I resolved it by

sudo apt remove --purge python3-virtualenv

from this post on stackoverflow.
