Does uninstalling a package with “pip” also remove the dependent packages?

Question

When you use pip to install a package, all the required packages will also be installed with it (dependencies). Does uninstalling that package also remove the d

Answer 1

You can install and use the pip-autoremove utility to remove a package plus unused dependencies.

# install pip-autoremove
pip install pip-autoremove
# remove "somepackage" plus its dependencies:
pip-autoremove somepackage -y

Answer 2

No, it doesn't uninstall the dependencies packages. It only removes the specified package:

$ pip install specloud
$ pip freeze # all the packages here are dependencies of specloud package

figleaf==0.6.1
nose==1.1.2
pinocchio==0.3
specloud==0.4.5

$ pip uninstall specloud
$ pip freeze

figleaf==0.6.1
nose==1.1.2
pinocchio==0.3

As you can see those packages are dependencies from specloud and they're still there, but not the specloud package itself.

As mentioned below, You can install and use the pip-autoremove utility to remove a package plus unused dependencies.

Answer 3

You may have a try for https://github.com/cls1991/pef. It will remove package with its all dependencies.

Answer 4

i've successfully removed dependencies of a package using this bash line:

for dep in $(pip show somepackage | grep Requires | sed 's/Requires: //g; s/,//g') ; do pip uninstall -y $dep ; done

this worked on pip 1.5.4

Answer 5

I have found the solution even though it might be a little difficult for some to carry out.

1st step (for python3 and linux):
pip3 install pip-autoremove
2nd step:
cd /home/usernamegoeshere/.local/bin/
3rd step:
gedit /home/usernamegoeshere/.local/lib/python3.8/site-packages/pip_autoremove.py
and change all pip(s) to pip3 4th step: ./pip-autoremove packagenamegoeshere

At least, this was what worked for me ...
