I have been scouring the internet, and cannot seem to find a solution to permanently adding an environment variable, specifically when my OS is macOS Mojave (10.14). It seems there are a lot of tutorials for past versions of the OS, but none for this one one. It also seems every old method has become outdated.
I want to add an environment variable ENV_VAR=12345
to my Mac, so that I can import it into a Python module using os.environ['ENV_VAR']
The most relevant tutorial I have found is this, but it doesn't quite do the trick for me. A lot of others tell you how to temporarily add environment variables to bash, but I don't think this is good enough. I want the addition to be there if you restart terminal.
Can you please either provide a short tutorial or point me to the correct/modern tutorial?
UPDATE: I should have mentioned that I use zsh
. This was key.

Bash
Since Bash is typically the default shell you can open up this file in your home directory:
And add your variable to this file:
You can do this without even having to edit this file if you like, using the following one-liner:
And then confirm like so:
After doing the above, if you open a new terminal you should see that environment variable has been set:
Zsh
If you find that you're using an alternative shell such as
zsh
, that uses a different set of configuration files maintained within your home directory,~
. Luckily the syntax of the changes is basically the same, just different files. So you can add the above example to this file instead:And then when you launch a
zsh
