Gem files will remain installed in /Users/ianseabock/.rvm/gems/ruby-1.9.3-p448/gems/therubyracer-0.10.2 for inspection. 
Results logged to /Users/ianseabock/.rvm/gems/ruby-1.9.3-p448/gems/therubyracer-0.10.2/ext/v8/gem_make.out 

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. 

Answer 1

遵循以下步驟：

Terminal

gem uninstall libv8 

Gemfile

gem 'therubyracer' 
bundle install 

就是這樣。你的libv8和therubyracer版本不匹配，所以你得到這個錯誤。

Answer 2

使用紅寶石2.2.0，它應該工作。

對我來說，它沒有與任何可能的設置與紅寶石2.1.x的工作。 隨着紅寶石2.2.0它工作順利。
