Hi all.
I’m using Windows 10 and Python 3.9.6. I attempted to upgrade to matplotlib 3.4.3 from 3.4.2 and the following error was displayed whether or not I used the administrator account:
WARNING: Ignoring invalid distribution -atplotlib (c:\users\biopr\appdata\local\programs\python\python39\lib\site-packages)
Installing collected packages: matplotlib
ERROR: Could not install packages due to an OSError: [WinError 5] Access is denied: ‘c:\users\biopr\appdata\local\programs\python\python39\Lib\site-packages\matplotlib\_c_internal_utils.cp39-win_amd64.pyd’
Consider using the --user option or check the permissions.

Thank you.
