`pip install pipreqs`

I get the error:

Python 3.11.2

Reproduce `pip install pipreqs` with Python 3.11.2 using the command and traceback in the issue. Start by examining the dependency metadata-generation failure involving docopt, py2app, and the missing fcntl module. Done means the installation failure is understood and a verified path to a successful installation is established.
