I thought
import sys
sys.path.append("/home/me/mydir")
is appending a dir to my pythonpath
if I print sys.path my dir is in there.
Then I open a new command and it is not there anymore.
But somehow Python cant import modules I saved in that dir.
What Am I doing wrong?
I read .profile or .bash_profile will do the trick.
Do I have to add:
PATH="/Me//Documents/mydir:$PYTHONPATH"
export PATH
To make it work?
On MAC OS you can simply find the location of python/python3 by using the command which python or which python3. (works for Linux too)
And it should give something like:
For python
/usr/local/bin/python
For python3
/Library/Frameworks/Python.framework/Versions/3.9/bin/python3
Export the path to your bash_profile
In your terminal type
sudo nano ~/.bash_profile
Enter your password and paste the following lines
PYTHONPATH="/Library/Frameworks/Python.framework/Versions/3.9/bin/python3"
export PYTHONPATH
Press control + x to exit, and press y for saving on being asked to save
Press `enter' to return to terminal window
Source it using the following command in terminal, run
source ~/.bash_profile
Path to python3 should be updated now!!
On MacOS Big Surf the file to add the "export" is $HOME/.zprofile
So, this should work for adding PYTHONPATH to your Mac Big Surf environment variables:
export PYTHONPATH=$HOME/my_folder
If the file doesn't exist just create it in $HOME, normally /Users/my_user_name
This change in the file name is because the default shell for MacOS Big Surf is zsh and not bash
In my .zshrc file located at /Users/your_username/.zshrc
I add the following line: export PYTHONPATH="${PYTHONPATH}:/your/path" and save it.
If the file doesn't exist, create a nameless .txt file and change its extension to .zshrc. It's a hidden file, so you need to press cmd+shift+. to see it.
I am using macOS Monterey.
