2021.3: pytest is failing on missimg 'all_timezones' variable

[kloczek]

I'm trying to package your module as an rpm package. So I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

• python3 -sBm build -w
• install .whl file in </install/prefix>
• run pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

Here is pytest output:

+ PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-pytz-2021.3-2.fc35.x86_64/usr/lib64/python3.8/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-pytz-2021.3-2.fc35.x86_64/usr/lib/python3.8/site-packages

The code in this repository is used to generate the pytz distribution, which includes adding the all_timezones data structure. You either need to run the tests using the the release tarballs, or run the code generation steps using the repo and test the generated code in the build/ subdirectory.

or run the code generation steps using the repo and test the generated code in the build/ subdirectory.

Where are those steps ansd why tose steps cannot be part of regulat build parocess?
