Unable to uninstall package named `-umpy`

Question

Runnig py -m pip list in windows powershell, produces:

Package         Version
--------------- -------
-umpy           1.15.4
autogui         0.1.8
         


        

Answer 1

import subprocess
print((bytes(subprocess.check_output(['pip', 'uninstall', '-umpy'], stderr=subprocess.STDOUT)).decode()))

To automate it in a python script.

Answer 2

Try

py -m pip uninstall -- -umpy

Double dashes separate options from non-options; used exactly in case like this.

BTW, I don't think -umpy is a real package. It seems it's a leftover from an unsuccessful uninstallation of a package numpy.

It could be you need to remove its directories manually. To do that, type py -m pip list -v to get a list of all installed modules together with their installation location and then simply delete the corresponding folders.
