pip install error error: Cannot uninstall'pyparsing' solution

1. Problem performance

I encountered an error when executing the pip install command to install pytest: Error: Cannot uninstall'pyparsing' 

 

Two, the solution

Execute sudo pip install -I pyparsing==2.2.2 command to upgrade pyparsing

Successfully installed pytest again, the problem is solved!
