I encountered similar problems when attempting

pip install --user --upgrade bcrypt

I had debian python-cffi package installed, version 0.8.6. After removing it the command above succeeded. The old version somehow caused problems even though new version of cffi had been installed using pip.

Also

pip uninstall  bcrypt cffi pycparser
pip install --user --upgrade cffi
pip install --user --upgrade bcrypt

seems to work even when python-cffi package is installed.

I still got an error, until I did "sudo apt-get install python3-dev"

This worked with python version 3.8.13. Windows Machine. Thank you!
