当我执行“捆绑更新”时，我从gem中获取错误，而不是在我的gemfile中。 我如何忽略这种依赖？
我正在使用一个使用twitter-bootstrap-rails的项目。 这个项目是在Linux机器上构建的，并使用therubyracer作为javascript运行时。 我一直在遇到问题，因为therubyracer似乎与Windows并不相处。
在windows上的therubyracergem
现在我正在尝试“捆绑更新”; “therubyracer”令人窒息。
我想我应该能够依靠JScript。 我如何告诉bundler忽略这一点，而不是深入研究每个gem并手动删除它对therubyracer的依赖？ 看起来像bootstrap，或者至少是twitter-bootstrap-rails，取决于therubyracer。
编辑：我已经按照该线程中的说明进行操作，并且我继续获得以下内容（在安装捆绑软件之后）：

Make sure that `gem install therubyracer -v '0.9.10'` succeeds before bundling. 有一个版本的twitter-bootstrap-rails使用静态CSS，不依赖于therubyracer。 在你的Gemfile中试试这个：
