horizon throws error 500 for missing django module

[alfred]

I used the rocky branch from git and turned on the dev mode in the all.yml. When I finished the deploy of openstack and tried to get access to the dashboard, the web throws the Error 500 like following:

> Internal Server Error
> The server encountered an internal error or misconfiguration and was unable to complete your request.
> Please contact the server administrator at root@localhost to inform them of the time this error occurred, and the actions you performed just before this error.
> More information about this error may be available in the server error log.

When I looked into the logs of horizon, it shows following errors:

As far as I can see from the log, it probably missed something. But how to fix it?

ps. When I turned off the dev mode, it works fine.
