heroku run rake db:migrate failed: command not found

Question

I'm a novie in heroku. When I was performing my CS169.1x homework2 (deploying an application) I ran into a problem with database filling using the following command: heroku run rake db:migrate. Here is terminal dump:

saasbook@saasbook:~/Documents/hw2_rottenpotatoes$ git pull heroku master
From heroku.com:afternoon-cove-7289
 * branch            master     -> FETCH_HEAD
Already up-to-date.
saasbook@saasbook:~/Documents/hw2_rottenpotatoes$ git push heroku master
Everything up-to-date
saasbook@saasbook:~/Documents/hw2_rottenpotatoes$ heroku run rake db:migrate
heroku run rake db:migrate: command not found
saasbook@saasbook:~/Documents/hw2_rottenpotatoes$

What may be wrong? If there is error dump on heroku to check?

This happened to me just now. Seemed as if rake was simply not installed on the heroku server - though it had been working earlier. All rake commands failed with command not found. Differed from a rake failure, because no "rake aborted!" message. Switched over to another heroku app in the same account and the same commands succeeded. — Colin

Have you installed the heroku gem? If you have heroku in the gemfile, you may need to do

bundle exec heroku run...

heroku run rake db:migrate failed: command not found
