As others have said this can be caused when you ve not installed an app that is listed in INSTALLED APPS   In my case  manage py was attempting to log the exception  which led to an attempt to render it which failed due to the app not being initialized yet  By  commenting out the except clause in manage py the exception was displayed without special rendering  avoiding the confusing error     Temporarily commenting out the log statement   try      execute from command line sys argv   except Exception as e       log error  Admin Command Error   s       join sys argv   exc info sys exc info         raise e
