How to completely uninstall pipx?

Question

I tried using poetry with pipx. Poetry used the wrong python version, so I deinstalled it and deinstalled the python version it was using, so when reinstalled it would use Python3.10 instead of 3.9.

Now without having Python3.9 I cant do anything with pipx.

[Fatal error in launcher: Unable to create process using (my path to my python version)]

How do I completely uninstall it so it uses Python3.10?

Answer 1

I received the same error message when I uninstalled Python 3.10 after installing Python 3.12 and tried to run pipx (installed with Python 3.10) or any package I had made available system-wide with it.

Here is what worked for me on my platform (Windows 11):

• edit your Path environment variable to remove references to previous Python version (3.10 in my case): type "environment properties" into Windows search bar, then in the System Properties window, click "Environment Variables", select Pathand click "modify"

• in C:\Users\[your_user_name]\.local, delete pipx directory

• in C:\Users\[your_user_name]\.local\bin, delete any .exe file referring to a package once installed with pipx

• in C:\Users\[your_user_name]\AppData\Roaming\Python, delete any directory referring to the previous Python or pipx version

• install pipx with your new Python: python -m pip install --user -U pipx then pipx ensurepath

Then running pipx in your terminal should not throw anymore an error and display help, as expected.
