Answer 1

Had the same issue (on Windows python 3.9.0 ).

Turns out cffi (1.14.X) installs fine on python version 3.8.9 and none other than that.

Answer 2

Pip decided that your system is not compatible. Please check if your Python version is compatible with the requirements of the module. You can get your Python version by executing python --version .
