After rake db:migrate I get this:

Gem::LoadError: You have already activated rake 11.2.2, but your Gemfile requires rake 11.1.2.

What should I do?

  • http://stackoverflow.com/questions/6588674/what-does-bundle-exec-rake-mean and http://stackoverflow.com/questions/8275885/use-bundle-exec-rake-or-just-rake have good information as to why you must do 'bundle exec', but it's not specifically about a gem version problem. – Marc-Andre Jul 21 '16 at 14:26
  • I'll keep this question in mind for future reference of this problem. It's a good clear enough question to be a good duplicate target. – Marc-Andre Jul 21 '16 at 14:26

Run:

bundle exec rake db:migrate

Basically the problem is that your local (rvm / rbenv / system) rake is of version 11.2.2. You might consider downgrading it with gem as well.
