Fails to same Python script from Terminal/Automator/Script Editor

Hi, I want to make a button on the menubar to run a Python script I made. To achieve that I thought to use Automator or Script Editor, but:

If I run the script on Terminal manually, all fine. (cd path/to/script && python3 myscript.py)

If I run exactly the same code in brackets using Automator shell function or Apple Script, they give me an error of a Python module not installed (but it's installed, I'm sure it is)

Any idea?

Your PATH and environment variables are extremely limited.

write an automator app with

printenv >~env.txt

save the app, and run it. Then look at env.txt

When you create your python script, compensate for any missing PATH directories and environment variables your python script my need

When you run Python in an Automator Run Shell Script, or Run AppleScript action, it is running Python 2.7.16, the default Python installation on macOS, because it hasn't a clue where Python3 is installed.

In order to run Python3 in an Automator Run Shell Script action, you need to use HERE syntax like the following in a Bash or Zsh shell:

You copy/paste the actual source code content of your script inside the Python HERE document right after the import statements. You don't select it to pass into the Run Shell Script action. You don't need that print statement that I used for the previous example.

You didn't follow the example exactly as your Passa a input: is set to come stdin, not as arguments. You will need to change that so you can pass the results from the previous action into your Python3 script code as sys.argv[1]. The only purpose of my example was to confirm the path to the Python3 (3.9.5) library.

What is the file that you have selected? Is it a Python module of some kind?
