terminal - "subl" command not found -

When I try to edit a file, such as ~ / .gemrc , At the terminal, I get this error:

  $ subl ~ / .gemrc -bash: subl: command not found    
 
 
 If it does not work and you are using RVM, then run:  ln -s "/ applications / Sublime Text 2" In both of these commands, it is believed that Sublime Lesson 2 is in your application directory Is cursed. If it is established by its elsewhere, its order changes.  
 Then, enter  export EDITOR = 'subl -w'  to enable editing with the  subl  command.
