Fixes #6213.
The
pip-wheel-metadata
directory does not need to persist between invocations of pip, use a temporary directory instead of the currentsetup.py
directory.This wraps the code dealing with
pip-wheel-metadata
inwith TempDirectory(delete=False) as temp_dir:
and replacesself.setup_py_dir
withtemp_dir
.Tests fail because they're configured to not allow temp files after the tests end (
AssertionError: temp files not expected
). I'm not sure best how to fix this, suggestions welcome!
