Whenever I am trying to install any package using pip, I am getting this import error:
guru@guru-notebook:~$ pip3 install numpy Traceback (most recent call last): File "/usr/bin/pip3", line 9, in <module> from pip import main ImportError: cannot import name 'main'
guru@guru-notebook:~$ cat `which pip3` #!/usr/bin/python3 # GENERATED BY DEBIAN import sys # Run the main entry point, similarly to how setuptools does it, but because # we didn't install the actual entry point from setup.py, don't use the # pkg_resources API. from pip import main if __name__ == '__main__': sys.exit(main())
It was working fine earlier, I am not sure why it is throwing this error.
I have searched about this error, but can’t find anything to fix it.
Please let me know if you need any further detail, I will update my question.
Now we will see solution for issue: Error after upgrading pip: cannot import name ‘main’
You must have inadvertently upgraded your system pip (probably through something like
sudo pip install pip --upgrade)
pip 10.x adjusts where its internals are situated. The
pip3 command you’re seeing is one provided by your package maintainer (presumably debian based here?) and is not a file managed by pip.
You can read more about this on pip’s issue tracker
You’ll probably want to not upgrade your system pip and instead use a virtualenv.
To recover the
pip3 binary you’ll need to
sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall.
If you want to continue in “unsupported territory” (upgrading a system package outside of the system package manager), you can probably get away with
python3 -m pip ... instead of
