-------------------------------+-----------------------------
 I recently upgraded from `py39-matplotlib @3.4.3_0+cairo+webagg` to
 `py39-matplotlib @3.5.0_0+cairo+webagg` and experience a problem when
 trying to import anything from matplotlib.

 {{{
 Python 3.9.9 (main, Nov 16 2021, 07:33:57)

 >>> import matplotlib
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File

 /site-packages/matplotlib/__init__.py", line 105, in <module>
     from packaging.version import parse as parse_version
 ModuleNotFoundError: No module named 'packaging'
 }}}

 Reactivating my previous matplotlib version fixes the issue.
