Thanks for the help. I imagine I might be a lost cause since I don't have the basic python skills to get this going.
1. I added the export path to my zsh file:
https://share.getcloudapp.com/12uDdEG1
2. I navigate to my /Applications/calibre.app/Contents/MacOS/calibre and launch it from iTerm2 but it still doesn't seem to be launching from the src folder.
I just updated to 4.9.1. If there is anything else I can try please let me know. I was going to try assisting on icons and graphic design related help.
