can't get gemfile to allow for bundle update

Question

I\'m a ruby/rails newbie.

Here is my gemfile:

source \'https://rubygems.org\'
ruby \'2.0.0\'
#ruby-gemset=railstutorial_rails_4_0

gem \'rails\', \'4.0.0         


        

Answer 1

Your problem is that you can only use one version of a gem at a time. the ~> will only allow for version changes on that gem.

You need to change the version of sass-rails you're requiring to 4.0.1.

Answer 2

You should update the following line in your Gemfile:

gem 'rails', '4.0.0'

to

gem 'rails', '~> 4.0.0'

and then run bundle update.

Answer 3

If you put sass-rails before rails in your Gemfile, it resolves correctly.
