I get this error when i try to run "rake test":
avery@ubuntu:~/rails_projects/depot$ rake test
rake aborted!
You have already activated rake 10.0.1, but your Gemfile requires rake 10.0.0. Using bundle exec may solve this.

how can i fix this?
回答1:
You probably have rake 10.0.0 in your Gemfile.lock.
Removing Gemfile.lock might solve the problem.
回答2:
For the first part of the question: I ran into the same problem and solved it with a:
gem regenerate_binstubs
after that
gem -V
reveals 10.0.0 again.
回答3:
Answer of 1st query
In your Gemfile, explicitly set the latest rake version by
gem 'rake', '~> 10.0.1'
And then run
$ bundle update rake
Answer of 2nd query
put this in your Gemfile and run bundle install
gem 'therubyracer'
回答4:
For the second part of the question, you just need to add this to your Gemfile:
gem 'therubyracer'
回答5:
If you've specified a rake version in your Gemfile that your project requires, eg:
gem 'rake', '~> 10.0.0'
Try installing it again
bundle install
