WARNING: Ignoring invalid distribution

[kucingkembar]

hi, every time I install using pip, I get this warning:

Error:
WARNING: Ignoring invalid distribution -rotli (c:\python\python310\lib\site-packages)

is this critical?
how to fix it?

When pip is removing a package,it first renames the first letter with a -.
If an uninstall fails the renamed directory keeps there,but it is invalid.
Manually delete the folder -rotli and upgrade pip.

python -m pip install --upgrade pip
