Love your work, I've spent hours trying to get this working on my latest Fedora build.
Thanks so much.

@LukeDRussell I'm glad it helped! 😃

Thanks bro. It was really helpful

Thanks for your sharing.
When I following your guide, I found that pyenv does not override the system python binary.
Here is the related issue link.
pyenv/pyenv#1906

You could replace the pyenv init - by pyenv init --path in line 16.
That can solve the problem.

Thanks!! It saved me.

Amazing - thank you so much

I'm on WSL and for some reason fish paths don't persist, so I had to add set -U fish_user_paths $HOME/.pyenv/bin $fish_user_paths to my ~/.config/fish/config.fish in order to get line 16 to work - other than that, fantastic!

Thanks so much!! Other tutorials made me reinstall WSL ㅠㅠ

Thanks to you, I got it!

This still works great, i'm using arch btw.
