ImportError: cannot import name 'Page'

Question

I have written a game in an Otree Project, but every time i want to clean my database or start the server, this message appears. It only happens with my game, but not when an example game is using that command.

Answer 1

Look in your app for the folder _builtin. There should be a file __init__.py that has the same contents as every other app's _builtin/__init__.py. If not, copy it from the other app.
