bundle install – 需要Ruby版本> = 1.9.2？
我刚开始使用Ruby on Rails进行一些开发并尝试在本地运行应用程序。 该应用程序正在安装了Ruby 1.8.7的生产环境中工作。
我在我的计算机上使用Ruby 1.8.7作为默认设置RVM。 但是，当我尝试运行bundle install ，我收到以下错误消息：
Gem::InstallError: mime-types requires Ruby version >= 1.9.2. An error occurred while installing mime-types (2.1), and Bundler cannot continue. Make sure that `gem install mime-types -v '2.1'` succeeds before bundling.
我试图在我的Gemfile寻找mime-types但却找不到它; 这让我相信它是来自另一个gem的依赖。
奇怪的是，生产服务器也是使用Ruby 1.8.7设置的，所以我不确定应用程序最初设置如何运行，尤其是当mime-types需要运行Ruby版本> = 1.9.2时。
我在生产服务器上的Gemfile.lock找不到mime-types ，因此无法确定哪些gem试图包含它。
有谁知道如何让这个应用程序在本地工作，所以我可以开始开发？
我对Ruby或Rails没有太多经验。
提前致谢。

如果您升级到OSX 10.9 Mavericks，这可能是由以前安装了ruby 1.8的旧版Bundler中的剩余可执行文件引起的，因为还没有为ruby 2.0安装Bundler。
通过安装bundler修复它：
sudo gem install bundler
这是一个完整的调查，证实这确实是问题的原因：
