I was getting an error with my application, so I looked on stack and found an answer undefined method `require_relative' for main:Object (NoMethodError) it said that I should run gem install rails which I did, after I ran that, when I tried to run rails generate controller StaticPages home help --no-test-framework I got an error:

  • try to run `bundle exec rails generate ...` – gotva Jan 15 '14 at 19:52
  • @gotva Do you happen to know why I need to run bundle exec because I have never needed to run that before – neils Jan 15 '14 at 19:57

    Actually you should do it for `rails`, `rake`, `rspec` etc. because Bundle knows what exactly versions of gems are used in the APP (Bundler takes versions from `Gemfile.lock`) - it means command will be started from correct source. PS if you haven't read about bundle - read [about bundler](http://bundler.io/) PPS did it help you? – gotva Jan 15 '14 at 20:01
  • @gotva Would the command be `bundle install .. ` to install the new versions of the rake, rspec and rails – neils Jan 16 '14 at 02:24

    it depends on your local environment. If you have `Gemfile.lock` and you have already run `bundle install` then NO `bundle` finds already installed gems and will use them. – gotva Jan 16 '14 at 05:55

Try deleting your Gemfile.lock (or perhaps moving it). This worked for me.
