I am developing my own Pack which I was able to get working, the action is a python script.
I added a 2nd Action by doing the following
–created and added new /action/newfile.py
–created and added new /action/newfile.yaml
–I did a git commit to both files
–did a pack install file:///$PWD
–did a st2ctll reload
Problem: newfile.pyc Does not get created
