An error occurred while installing therubyracer (0.10.2), and Bundler cannot continue.
Make sure that `gem install therubyracer -v '0.10.2'` succeeds before bundling.

You have to compile `libv8` with g++ 4.2, see the linked question for details. — Stefan, Nov 04 '13 at 18:40

Follow these steps:

Terminal

gem uninstall libv8

Gemfile

gem 'therubyracer'
bundle install

That's it. your libv8 and therubyracer version were not matching, so you were getting that error.

Use ruby 2.2.0 and it should work.

For me it didn't work with ruby 2.1.x with any possible setting. With ruby 2.2.0 it worked smoothly.
