how to cleanly uninstall my python packages with pip3 or any other way?

问题

this is my setup.py file for installing my python program, after the installation using python3 setup.py install an entry to my program was created named testmain , when i did pip3 freeze it showed abc==0.1 in its output ,so i uninstalled it using pip3 with pip3 uninstall abc , though the packages were uninstalled but there still existed the entry testmain on my path , is there a way that pip3 also removes this entry during the uninstall or any other way that i can cleanly uninstall my programs under same scenario ?

from setuptools import setup

setup(name='abc',
      version='0.1',
      description='test',
      url='http://github.com/rjdp',
      author='rajdeep',
      author_email='rajdeep.sharma@rtcamp.com',
      license='MIT',
      packages=['cli'],
      install_requires=[
      'cement',
      ],
      entry_points = {
      'console_scripts': ['testmain=cli.abc:main'],
      },
      zip_safe=False)

回答1:

Instead of python3 setup.py install use:

pip3 install .

then

pip3 uninstall abc

This will remove testmain.

I had the same question today and spent the entire morning trying to figure out why the script wouldn't uninstall. Nothing worked until I saw Ramana's answer here: https://askubuntu.com/questions/38692/how-does-one-remove-applications-installed-through-python-setup-py-install

"You should always install Python apps with "pip". pip supports uninstall option." and the example in the commment on how local path is supported.
