Please do the following steps to fix the problem:

1. Make sure that the following commands returns the proper version of ruby:

   $ rbenv versions
     system
     2.0.0-p353
   
   $ rbenv local
   ruby-2.0.0
   
   $ rbenv version
     2.0.0-p353
   

2. Make sure that getting the version of ruby is correct:

   $ bundle exec ruby -v
   ruby 2.0.0-p353 (2013-11-22 revision 43784) [x86_64-linux]
   

3. If you got invalid version of ruby, you shell to verify that problem is in bundler by calling:

   $ bundle exec ruby -v
   ruby 1.8.7
   
   $ which bundle
   /usr/bin/bundle
   

   It says that it will call system ruby to proceed ruby scripts.

4. Reinstall bundler, and then make sure that now current ruby is valid:

   $ gem install bundler
   
   $ bundle exec ruby -v
   ruby 2.0.0-p353 (2013-11-22 revision 43784) [x86_64-linux]
