问题
I was unaware that pip could be installed via my operating system's package manager, so I compiled and installed pip via source with the following command:
wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | sudo python
I would like to uninstall pip, and instead install it from my operating system's package manager. How would I go about completely undoing the work of the installation script?
回答1:
That way you haven't installed pip, you installed just the easy_install i.e. setuptools.
First you should remove all the packages you installed with easy_install using (see uninstall):
easy_install -m PackageName
This includes pip if you installed it using easy_install pip.
After this you remove the setuptools following the instructions from here:
If setuptools package is found in your global site-packages directory, you may safely remove the following file/directory:
setuptools-*.egg
If setuptools is installed in some other location such as the user site directory (eg: ~/.local, ~/Library/Python or %APPDATA%), then you may safely remove the following files:
pkg_resources.py
easy_install.py
setuptools/
setuptools-*.egg-info/

If you installed pip like this:
- sudo apt install python-pip
- sudo apt install python3-pip
Uninstall them like this:
- sudo apt remove python-pip
- sudo apt remove python3-pip

I was using above command but it was not working. This command worked for me:
python -m pip uninstall pip setuptools
