I am trying to install python camellia (https://pypi.org/project/python-camellia/) and am getting this as an error:

[...]Temppip-install-k55xzoj1python-camellia_f66ad56a78554286b3a99832c02cbd94srccamellia_build_build_utils.py", line 8, in <module>
          from cffi import FFI
      ModuleNotFoundError: No module named 'cffi'
      [end of output]

I, obviously, first of all went and tried to install CFFI, was already there (I knew that) so no surprises.

pip3 install cffi

I then tried to upgraded (did need an upgrade) so I tried again after.

pip3 install --upgrade cffi

No dice, same result. I am heavily confused as to why this is since camellia is such an old module used in a couple of repos I know of, this is my personal first try at using it but a friend of mine has no issues with it…
