rake django admin error - mitocw/edx-platform GitHub Wiki

when I wan to delete a course, I execute the command as follow ：

edxapp@edx:/edx/app/edxapp$ pwd
/edx/app/edxapp
edxapp@edx:/edx/app/edxapp$ rake django-admin[delete_course,cms,aws,"56Team/CT001/Linux commit"]
rake aborted!
No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)

(See full trace by running task with --trace)

can you tell me how to do ? Thank you !
