importError in Automator while running Python 3 script in shell /bin/bash

Question

I'm trying to add my python3 script to Automator using the shell /bin/bash, but keep getting the error:

"ImportError: No module named watchdog.observers”"

Which I assume is because it runs Python 2 and not 3. After searching on the internet I came up with the following./bash_profile and shebang line, but it still does not seem to work. This is what I tired in the automator:

This is what my bash_profile looks like:

And finally this is what the first lines in the Python script looks like:

And when I then run the Automator I get the following error message:

Why do I get the import error and how do I fix it?

Answer 1

Okay, so I solve it. In the Automator (shell /bin/bash) I did:

/Users/username/Documents/categorize_downloads.py

Before that I had change permissions on the file I wanted to run, so:

chmod 755 filename

And then finally I changed the shebang to:

#!/usr/local/bin/python3

It seems to be cases when "env python3" could be used instead, but in this case I had to remove "env".
