Python3 Pip Not Working on My Pi

Question

So I was having some trouble with python package incompatibilities. I was tired of troubleshooting and decided that I would remove all of the packages that I had installed using pip3. In an attempt to do this, I stupidly removed all files under the /usr/lib/python3/dist-packages directory using this command:

sudo rm -R /usr/lib/python3/dist-packages/*

After doing this, I tried to use pip3 to reinstall the packages that I needed, but all of a sudden, the pip3 command would not work and instead display a lengthy error message. I tried uninstalling and reinstalling python3-pip and python-pip, but the error would not go away. At this point, I don't know what to do to fix pip3, so I would really appreciate any help with helping to understand the error message, and to fix the problem. Here is the error message that I get when I try to install any package using pip3 (I get the same error when I use pip as well):

`Exception:

Here are the results of running pip3 -V:

pip 18.1 from /usr/lib/python3/dist-packages/pip (python 3.7)

I don't know if that information would be useful, but I figured that I would include it. Once again, I would really appreciate any help in understanding the error and fixing the issue. Thanks for any responses in advance!

Answer 1

So I was able to fix the issue by uninstalling python and autoremoving and then reinstalling python:

sudo apt-get purge python python3 python-pip python3-pip

sudo apt autoremove

sudo apt-get install python python3 python-pip python3-pip

Unfortunately, I still don't know exactly what caused the issue, but this approach did solve the issue for me.

Answer 2

You must reinstall everything that has connection with python2 and python3. This can fix your problem.
