Request bump in py7zr dependency version to allow 0.11

I write open source applications for researchers and your tools are very helpful. ありがとうございます

I’m trying to use the Install Qt GitHub Action with the ubuntu-16.04 runner which only has Python 3.5. You fixed py7zr compatibility with Python<3.8 in version 0.11 (this commit: https://github.com/miurahr/py7zr/commit/db895a91f3fe5ef22203bccbfb72dfa7d2f64a21). Unfortunately, even if I specify with: py7zrversion: '>=0.11', the aqtinstall requirements takes over because it explicitly demands py7zr <0.11. https://github.com/miurahr/aqtinstall/blob/master/setup.cfg#L38

You updated this dependency recently, but is it possible to please update it again to <=0.11?

You’re right! I’m so sorry for the confusion. It appears to be a problem with importlib_metadata. See https://github.com/python/importlib_metadata/issues/259 for example.

Hopefully they fix it soon. In the meantime, it is possible to pip3 install importlib-metadata==2.1.0. I’ll see if I can get the runner to do that before installing Qt. Edit: Unfortunately installing importlib-metadata first didn’t seem to fix the problem. I will wait for an upstream fix.

For reference, here is the Actions page: https://github.com/labstreaminglayer/App-LabRecorder/runs/1451188135?check_suite_focus=true The most recent error run shows the problem I’m talking about.

The error is collapsed below.

Dear Miura-san, I would like to update with you with what I believe is the correct identity of the problem.

The GitHub Actions Ubuntu 16.04 runner comes with pip version 8 which does not respect the python_requires flag. Thus the install-qt-actions script was downloading and installing the latest versions of these packages even though you have correctly marked them as incompatible with python 3.5. For anyone who finds this issue in the future, you can find my workaround for that particular problem here.

Best regards.
