Issue

importlib-metadata 3.6.0 changed the behaviour of entry_points() to no longer return a dictionary of entry points but instead return an object with a deprecated dict-like interface. As of importlib-metadata 3.9.0 a DeprecationWarning is emitted when calling the dictionary methods.

virtualenv calls .get() here:

virtualenv/src/virtualenv/run/plugin/base.py

Lines 16 to 18 in 3f41067

@classmethod
def entry_points_for(cls, key):
return OrderedDict((e.name, e.load()) for e in cls.entry_points().get(key, {}))

This results in the following warning:

$ python3.6 -Wdefault -m virtualenv /tmp/venv
virtualenv/run/plugin/base.py:18: DeprecationWarning: SelectableGroups dict interface is deprecated. Use select.
  return OrderedDict((e.name, e.load()) for e in cls.entry_points().get(key, {}))

Environment

Provide at least:

  • OS: Ubuntu 20.04

  • pip list of the host python where virtualenv is installed:

Output of the virtual environment creation

Make sure to run the creation with -vvv --with-traceback:

See python/importlib_metadata#278 and python/importlib_metadata#289 for more context. The changelog for importlib-metadata suggests https://pypi.org/project/backports.entry-points-selectable/ as a possible solution.

This is currently only an issue on Python 3.7 and earlier, as virtualenv uses the standard library on newer versions.
