While following the Rails 4 Beta version of Michael Hartl's Ruby on Rails Tutorial, my app fails to start on Heroku, but runs fine locally with bundle exec rails server
. Checking heroku logs -t
reveals the following error:
$ heroku[web.1]: State changed from crashed to starting
$ heroku[web.1]: Starting process with command `bin/rails server
-p 33847 -e $RAILS_ENV`
$ app[web.1]: bash: bin/rails: No such file or directory
$ heroku[web.1]: Process exited with status 127
$ heroku[web.1]: State changed from starting to crashed
$ heroku[web.1]: Error R99 (Platform error) -> Failed to launch the
dyno within 10 seconds
$ heroku[web.1]: Stopping process with SIGKILL
If I heroku run bash
and check the bin
directory, I can see that there is not a rails
executable:
~$ ls bin
erb gem irb node rdoc ri ruby testrb
What have I done wrong? I followed the tutorial exactly.
I had this problem also since I upgraded to rails 4.0.0
Run this command
rake rails:update:bin
