Hi i was doing some coding and tried to 

rake routes

and this error message came up out and i dont know what to do

rake aborted!
Gem::LoadError: You have already activated rake 10.4.2, but your Gemfile requires rake 10.4.0. Prepending `bundle exec` to your command may solve this.

You can remove the older version of the gem by using :

gem uninstall rake --version=[Here version that you want to delete]

After uninstall just use rake routes normally.

There were two answers for me:

  1. Temporary solution:

bundle exec rake routes

  1. Permanent Solution

gem update rake and then rake routes

If you need to use older version just remove newer version:

gem uninstall rake --version=<newer version>

In your case:

gem uninstall rake --version=10.4.2

You generally shouldn't manually edit gemfile.lock. And if you do delete the file and restart from scratch make sure the versions of you gems in your gemfile are specified so you'll get the ones back that you expect. For this situation:

$ bundle update rake

worked for me.

  1. manually delete you gemfile.lock file
  2. run bundle install

That fixed the problem for me.

The command 

bundle exec rake routes

makes it work, but it's way better if you pick the right version of rake needed and change it in your Gemfile.lock

You probably want to update your gemfile.lock and change the version of rake from 10.4.0 to 10.4.2 an you can continue working as you were before this problem.

I just ran into this issue today. I used RubyMine to build a new project and it installed rake 10.4.2. For my work I have to use 10.3.2 for db:migrate.

RubyMine solution: To fix the problem in RubyMine I opened opened up the run configuration for db:migrate, went to the Bundler tab and checked "Run the script in context of the bundle (bundle exec)"

I got this problem on an old project after running the command rails new MyNewProject

To fix it on the old project I just went into the Gemfile.lock file and searched for rake. The I found rake (10.3.2) and replaced it with rake (10.4.2) and that fixed it for me.

This error is because your gem file is using a different version of rake, so you need to specify which of the rake versions you need, so this can help you

 bundle exec rake routes
