Error=To install Python packages system-wide, try 'pacman -S
 python-xyz', where xyz is the package you are trying to
 install.

 If you wish to install a non-MSYS2-packaged Python package,
 create a virtual environment using 'python -m venv path/to/venv'.
 Then use path/to/venv/bin/python and path/to/venv/bin/pip.
