Python not interpreting changed files, using obsolete .pyc

Question

Using the Google App Engine to develop in python yesterday it stopped running the current version of the script. Instead of executing the most recent version it seems to run

Answer 1

The following steps solved the issue temporarily:

1. Delete GoogleAppEngineLauncher from your Applications folder.
2. Rename the file ~/Library/Application Support/GoogleAppEngineLauncher/Projects.plist (e.g. Project.plist.backup
3. Rename the file ~/Library/Preferences/com.google.GoogleAppEngineLauncher.plist (e.g. com.google.GoogleAppEngineLauncher.plist.backup)
4. Download and install Google App Engine Launcher again.
5. Use "File", "Add existing application…" to add your projects again, do not forget to set any flags you had set before.

Alternatively it might even work starting GAEL once, closing it and putting your backed up preference files back into place as to avoid having to reconfigure.

Edit: Turns out that fixes it… temporarily. Not exactly a very easy issue to debug. Weirdly enough it works when running the appserver from the command line, such as

dev_appserver.py testproject/ -p 8082 --debug
