Gem gem "therubyracer" 安装出错
在 Gemfile 中写了 gem "therubyracer" 据说要安装两个 gem gem install libv8 gem install therubyracer 执行 gem install libv8 时出错了，如下： E:>gem install libv8 Temporarily enhancing PATH to include DevKit... Building native extensions. This could take a while... ERROR: Error installing libv8: ERROR: Failed to build gem native extension.

求救啊，这是什么错
gem "therubyracer" 执行 bundle install 时，也会出现同样的错误

我觉得这种错误，google 才是万能的。 http://stackoverflow.com/questions/8126465/bundle-install-update-libv8-therubyracer-installation-fails-with-native-ex 不是 windows 的，不知道能不能解决你的问题
