Your Ruby version is 2.1.0, but your Gemfile specified 2.0.0

Question

In my Gemfile I specified ruby version 2.0.0:

ruby \'2.0.0\'

But my console tells me I have 2.1.0dev:

$ ruby -v
ruby 2.1.0d         


        

Answer 1

Go to your Gemfile and change the description there I just got the same problem and couldn't find a "working" solution. So I made my own.

source 'https://rubygems.org'
ruby '2.0.0' #Change this one to this '2.1.0'

gem 'rails', '4.0.3'

Answer 2

You may need to update your version of ruby-build to make sure you have the update where ruby-2.0.0-dev switched to follow the ruby_2_0_0 branch.

Try running ruby-build --version and make sure it's one of these (or later):

• v20130907
• v20130901
• v20130806
• v20130628
• v20130518
• v20130514
• v20130501
• v20130408
• v20130227
• v20130226
• v20130225

If not, run brew upgrade ruby-build.
