Okay, that one's easy enough to deal with!

You have something that needs to build a C extension. To do that, you
need to have the Python headers installed. How did you install Python?
On Debian/Ubuntu family Linuxes, that's probably "apt-get install
python3" - so getting the headers would be "apt-get install
python3-dev". Give that a try, and then retry the pip install.
