Unable to install properly while following the guide

[Ng Si Qiang]

Hi, I have encountered this problem when I tried to install. Would you mind helping me with it?

[error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 2] No such file or directory: '/usr/lib/python3.8/site-packages/test-easy-install-358.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /usr/lib/python3.8/site-packages/

This directory does not currently exist.  Please create it and try again, or
choose a different installation directory (using the -d or --install-dir
option).](url)
