I installed Rails 4.2.3 on Mac OS X Yosemite, but when I try to start the server, I get this error message

Companys-MacBook-Pro:App MyUser$ rails server
Could not find nokogiri-1.6.1 in any of the sources
Run `bundle install` to install missing gems.
Companys-MacBook-Pro:App MyUser$

so I tried this

sudo gem install nokogiri -v=1.6.1

then I got these errors

Companys-MacBook-Pro:~ MyUser$ sudo gem install nokogiri -v=1.6.1

I then followed the instructions on nokogiri website to install libxslt, libxml2, and libiconv

Companys-MacBook-Pro:~ MyUser$ brew install libxml2

Companys-MacBook-Pro:~ MyUser$ brew install libxslt

and still no luck. I also tried

but rails server still does not start because it requires nokogiri 1.6.1

Companys-MacBook-Pro:App MyUser$ rails server

Anyone has an idea what's going on here?

EDIT 1 I did run bundle install and still the same issue ; this is the output

Do you have nokogiri listed in your Gemfile? If not add it and if so what version is it specifying? – xkickflip
Thanks @xkickflip for your prompt answer. I added "gem 'nokogiri', '~> 1.6.1'" to Gemfile and ran "bundle install"but I still have the same issue – rh4games
Is there another Gem specifically depending on 1.6.1? It'll be listed as a dependency in Gemfile.lock. You can try upgrading that gem to a newer one that will run with nokogiri 1.6.6.2 (if such a version exists) since that installed for you already. – xkickflip
Thanks @xkickflip for the idea. I did change the version in Gemfile and Gemfile.lock to 1.6.6.2, ran "bundle install" again and all worked fine. You made my day ! Please change your comment to and answer so I can give credit for it. Thanks a million. – rh4games
"sudo gem install nokogiri -v=1.6.1 ". You're installing software into Apple's installation of Ruby. Don't. Instead, use RVM or rbenv to install a Ruby in a sandbox where you can mess with it to your heart's content. – the Tin Man

One of issues was that you were manually installing Nokogiri 1.6.6.2, but not including the nokogiri gem entry in your Gemfile. Bundler will specifically only show your app the gems that are listed in the file.

It wasn't clear to me if you were tied to nokogiri 1.6.1 because it was a dependency of another gem. If there was another gem calling for 1.6.1 then you would investigate a newer version of that gem, which hopefully depended on the newer Nokogiri. bundle update <othergem> would attempt to do so.

Just wanted to be clear that I wasn't suggesting modifying another gem's dependencies in your lock file as they were set for a reason by that gem's author.

Since you initially specified gem 'nokogiri', '~> 1.6.1' in your Gemfile you were locked to that after the first bundle install. bundle update nokogiri would try to update you to the latest. Or manually changing the Gemfile to 1.6.6.2 or more loosely ~> 1.6 or 1.6.6.

Also, as @the Tin Man mentioned using sudo install to put gems into the Apple system ruby isn't the best way to go. I definitely recommend using one of the Ruby version managers like RVM or rbenv as he linked in his comment.
