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.
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 pip3.
We can clear the error by modifying the pip file.
Check the location of the file:
$ which pip
path -> /usr/bin/pip
Go to that location(/usr/bin/pip) and open terminal
Enter: $ sudo nano pip
You can see:
import sys
from pip import main
if __name__ == '__main__':
sys.exit(main())
Change to:
import sys
from pip import __main__
if __name__ == '__main__':
sys.exit(__main__._main())
then ctrl + o write the changes and exit
Hope this will do!!
