rake db:miagrate aborted abnormal: rake aborted! uninitialized constant Rake::DSL

Anyone could help me? I searched the same problem, but I can't figure out a solution still. I ran successfully with "bundle update" "bundle install" but when running "rake db:migrate" I got the following problem...

Solution

  • Put this in your Rakefile above require 'rake': 

    require 'rake/dsl_definition'

    OR if the above solution does not work,

    write this in your gemfile for rake

    gem "rake", "0.8.7"

    and go to command prompt and write.

    gem uninstall rake

    This will uninstall the existing rake gem.

    Then type bundle update in your project folder which will install rake 9.8.7 again.

    And enjoy rails :).
