Jupyter Notebook doesn't Uninstall package with pip

Question

I tried to remove a package with pip in a Jupyter notebook but it never finishes and I have to eventually restart the kernel without it uninstalling. I tried:

!python -m pip uninstall pyserial

I found out why it hangs up. When running it from the command line, it asks whether I want to uninstall with a yes/no required.

Uninstalling pyserial-3.4:
  Would remove:
    c:\Anaconda3\lib\site-packages\pyserial-3.4.dist-info\*
    c:\Anaconda3\lib\site-packages\serial\*
    c:\Anaconda3\scripts\miniterm.py
Proceed (y/n)?

Perhaps the confirmation is a new feature of pip? It doesn't seem to be a problem in How to uninstall a package installed with pip install --user. Is there a way to insert a yes response from the Jupyter notebook to not block future cells from running?

Solution

Try adding --yes to automatically answer the yes/no question.

!python -m pip uninstall pyserial --yes

This uninstalls the package pyserial. You can use the --yes from the command line or in a Jupyter notebook cell.

Uninstalling pyserial-3.4:
