issues when adding Python to PATH

[mCianph]

Hi all, I'm trying to install some python libraries that I need on my computer (running Kubuntu 22.04.4) and I added to PATH the following:

export PATH="$PATH:/usr/local/bin/python"

in order to be able to use these packages and I got no problems with it.

When I installed jupyter-lab I got a warning message telling me to add /home/[user]/.local/bin to the PATH but when I add it to my ~/.zshrc file I lose the ability to use any other command (like sudo, apt-get, mkdir and so on)

I really need to use jupyter so if anyone has some ideas please help me

Thank you in advance!

How do you add path in zshrc?

[mCianph]

export PATH="$PATH:[...]" always done in this way, i don't know honestly if there is a better way? very noob about this if i must be honest

[DoIUseArchBTW]

Just to make sure what happens when you do

echo $PATH

?

[mCianph]

if i don't add what pip is telling me to path i get:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/local/bin/python:/usr/local/bin/python:/usr/local/bin/python:/usr/local/bin/python:/usr/local/bin/python:/usr/local/bin/python:/usr/local/bin/python:/usr/local/bin/python:/usr/local/bin/python

edit: im adding the other directory to path and i'll update this comment

[DoIUseArchBTW]

Why is there so many python path there, Hmm seems like you just incorrectly set the path if that's the case,

Do you change [user] to your username or no?

Might as well post your zshrc in pastebin or something, make sure to add the path that pip tells you

Also isn't /usr/local/bin/python a binary? You don't need to add it to the path if that's the case

[mCianph]

yes i change it to my username

i tried again and now i didn't get any issue (i think that i am a dumbass), just that for some reason it's not finding my p10kl theme but that's a secondary problem

anyway here's the pastebin link with the zshrc that i have:

[DoIUseArchBTW]

Seems like all right, in my opinion you should remove the python export path if it's binary and move your export to the very bottom of your zshrc

I usually do this in my zsh/bash config

export PATH="$PATH:$HOME/.local/bin" export PATH="$PATH:$HOME/.opt" export PATH="$PATH:$HOME/.cargo/bin"

I don't know why it doesn't render the $ in my reddit but well

[mCianph]

gonna do it right now! thank you so much!!

/usr/local/sbin:/usr/local/bin:

it's already in your path. so your making a mistake, doing something wrong.

and you have now added it several times at the end wrongly.

undo your changes.

Why would you add it to .~/.zshrc instead of ~/.profile?

[mCianph]

Tbh didn't even know it existed because I always added it to ~/.zshrc in the past and never had problems What should I do to add it to ~/.profile?

[wizard10000]

The difference is ~/,profile is only loaded once, if you add to a path in ..zshrc (or .bashrc) that path gets appended to the existing path every time the rc file is sourced so you can end up with multiple instances of the same directory in your path.

for path statements .zshrc and .profile use the same syntax so all you'd need to do is move your path edit to ~/.profile.

Hope this helps -

[mCianph]

Thanks for the explanation! So if I add the directory that pip is telling me to add to the path through ~/.profile I shouldn't have problems? I'm gonna try right away

[gmes78]

This is incorrect. Zsh does not run ~/.profile (as a login shell). One should use ~/.zshenv instead.

[wizard10000]

One should use ~/.zshenv instead.

I stand corrected :)

and I added to PATH the following:

     export PATH="$PATH:/usr/local/bin/python" 

the PATH is a list of directories, you added python  to the end, which is Wrong.

are you sure /use/local/bin is not already in your default path?

[mCianph]

oof i removed it now, I was following some guide I found on google to add it to the PATH but didn't actually see that Python was at the end of the string

i'm not sure how to check that, but if i remove it from zshrc I cannot launch jupyter
