Summary of changes
Since version v20.23.0,
virtualenv
will no longer includewheel
andsetuptools
in the created folders.Some tests in the setuptools test suite assume that these packages are always present. So we need to adequate these tests.
EDIT: Apparently we are also having problems with
__version__
. It seems that the code path triggered in the "unhappy path" that results in__version__ = "unknown"
.Since
unknown
is not a valid PEP 440, it causes problem. I changed this fallback to be PEP 440-compliant.This problem might be related to the race conditions between
importlib.metadata
(used by pytest and plugins) andegg_info
(that writessetuptools.egg-info/PKG-INFO
).Closes
