Versions 2.0.0 and 2.0.1 were yanked from PyPI last week due to an issue where discovery documents were not included in the published package causing discovery.build() to fail(#1214). A basic check could be added to verify the package works correctly using the steps in #1214. Ideally it should be done on every PR and push to master so the issue can be caught before the package is published.

Use these steps from #1214 to re-produce the issue with version 2.0.0 and 2.0.1:

1. Start with a clean clone of google-api-python-client
2. Checkout version 2.0.0 or 2.0.1, using git checkout 2.0.0
3. Run python setup.py sdist
4. Run pip install dist/google-api-python-client-<version>.tar.gz
5. Run

$ python3
Python 3.8.7 (default, Jan 27 2021, 18:44:05)

Type "help", "copyright", "credits" or "license" for more information.
>>> from googleapiclient import discovery
>>> client = discovery.build("cloudprofiler", "v2")
...

Before closing this issue, we should ensure that we have checks in place so that a PR will fail if package_data here is empty.
