install error with rails 4 using sudo gem install

Question

recently upgraded to os x , installed ruby 2.0 trying to install rails 4

Neils-MacBook-Pro:code neilpatel$ rails --version

Rails is not currently installed on this system. To get the latest version, simply type:

$ sudo gem install rails

You can then rerun your "rails" command.

Neils-MacBook-Pro:code neilpatel$ sudo gem install rails

Answer 1

gem install rails --version=4.0.0.rc1 

The version of rails should be specified before installing the gem.

if your ruby version is 2.0.0 then install the rails 4 gem.
