setup.py(Removed some code in order to have less code)

import sys
import os
import setuptools
from setuptools.command.install import install

class PostInstall(install):
    def run(self):
        mode = 0o666
        bashrc_file = os.path.join(os.path.expanduser('~'), ".bashrc")
        install.run(self)
        # Added CLI to .bashrc
        # Change "config.json" file permission


setuptools.setup(
      ...
      entry_points={'console_scripts': ['funmotd = funmotd:main']},
      package_dir={'funmotd': 'funmotd/'},
      package_data={'funmotd': ['config.json'], },
      include_package_data=True,
      python_requires=">=3.4",
      cmdclass={'install': PostInstall, },
      ...      
)

The PostInstall is executing fine when I run python3 setup.py install. So, uploaded to Pypi like below(From this doc)

$ python3 setup.py bdist_wheel
# Created "dist", "funmotd.egg-info" and "build" dirs
$ twine upload dist/*

But when I run pip install funmotd, PostInstall is NOT executing, I see that dist/* is like static compiled stuff. Is there any trick to run post installation tasks when I run pip install funmotd. Or how to make setup.py execute at pip.

I Followed below questions, didn't get solution what I need

Post-install script with Python setuptools
Run custom task when call `pip install`

PS: I don't want users to clone repo and run python setup.py install. Want to make it simple pip install funmotd

Seems there is already issue on github which is long thread

回答1:

pip doesn't run setup.py from a wheel hence you cannot run any post-installation code from setup.py in a wheel.

setup.py is used to build wheels or used during installation of source distribution (sdist). So if you want post-installation script stop uploading wheels to PyPI, only release source distribution (python3 setup.py sdist). Then pip install funmotd will run code from setup.py.

回答2:

You need to invoke the parent run, first, before executing the rest of your PostInstall, could you try:

class PostInstall(install):
def run(self):
    install.run(self)
    mode = 0o666
    bashrc_file = os.path.join(os.path.expanduser('~'), ".bashrc")
    # Added CLI to .bashrc
    # Change "config.json" file permission

This hopefully will solve the problem - I've had problems with something very similar myself, works locally, but not through pip.
