How to prevent accidental publish Python pacakge using setup.py

Question

Is there a way to prevent accidental publication of private package such as "private": true in NPM?

Answer 1

You can add something like this to the top of your setup.py script:

import sys

for arg in sys.argv:
    if arg in ('upload', 'register', 'testarg'):
        print('This setup is not designed to be uploaded or registered.')
        sys.exit(-1)

You can test it works safely by doing:

python setup.py testarg

This should display a message and immediately exit.
