Is there a way to uninstall multiple packages with pip?

Question

I am attempting to remove all of the installed "pyobjc-framework"-prefixed packages. I have tried the following:

% pip freeze | grep pyobjc-framework | xargs pip uninstall 

but this barfs because each pip uninstall requires confirmation (perhaps a way to bypass this would be a solution).

Please help before I have to break down and uninstall each of these manually! Nobody wants that.

Answer 1

Your command should actually work if you add the -y | --yes flag to pip :-)

-y, --yes Don't ask for confirmation of uninstall deletions.

Possibly:

% pip freeze | grep pyobjc-framework | xargs pip uninstall -y

Answer 2

Redirect the grep output to a new file and run.

 pip uninstall -r <file name>

works I think.

pip freeze | grep pyobjc > packages_to_remove.txt
sudo pip uninstall -y -r packages_to_remove.txt

Answer 3

I always use this:

pip freeze | xargs pip uninstall -y

Answer 4

greping pip freeze returned:

Usage:   
  pip uninstall [options] <package> ...
  pip uninstall [options] -r <requirements file> ...

no such option: -e

So I did it with pip list instead:

$ pip list | grep tempest | xargs pip uninstall -y
