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 13] Permission denied: '/usr/local/lib/python3.6/dist-packages/test-easy-install-32566.write-test' The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was: /usr/local/lib/python3.6/dist-packages/ Perhaps your account does not have write access to this directory? If the installation directory is a system-owned directory, you may need to sign in as the administrator or "root" account. If you do not have administrative access to this machine, you may wish to choose a different installation directory, preferably one that is listed in your PYTHONPATH environmentvariable. For information on other options, you may wish to consult the documentation at: https://setuptools.readthedocs.io/en/latest/easy_install.html Please make the appropriate changes for your system and try again.
You might want to update your setuptools – maybe also pip and so on:
sudo python3 -m pip install -U pip setuptools
That solved this for me.
