  • Don't know if this the cause for your issue, but as the message itself states right there in the top, Python 2 is not supported by pip and you should upgrade to a newer version (current latest is 3.8) – Tomerikoo Feb 28 '20 at 12:31

You do need to install the Python2 C headers. For instance, in Ubuntu:

sudo apt-get install build-essential python-dev
