sh: php_beautifier: command not found

[humanitiesclinic]

Hi I have:

sh: php_beautifier: command not found

This error.

Do I have to install something?

How exactly do you run the script?

[humanitiesclinic]

$ ./translate_python_to_php TARGET.py

I ran it in the directory I downloaded from this Github.

Then I got:
sh: php_beautifier: command not found
failed!
