我的 gems 依赖项有问题：Gemfile 的内容是

source :gemcutter
gem "sinatra"
gem "koala"
gem "json", "1.5.5"
gem "httparty"
gem "thin"
gem "rack", "1.3.10"

这个bundle install错误击中了我

$ sudo bundle install

Gem files will remain installed in /var/lib/gems/1.9.1/gems/eventmachine-0.12.10 for inspection.

An error occurred while installing eventmachine (0.12.10), and Bundler cannot continue.
Make sure that `gem install eventmachine -v '0.12.10'` succeeds before bundling.

但是，我确实安装了 eventmachine！：

$ gem list

*** LOCAL GEMS ***

eventmachine (1.0.3, 1.0.0.rc.4, 0.12.10)

救救我，你是我唯一的希望！谢谢你。

ruby 1.9.1 在 C 扩展上有一些问题。尝试检查您是否有mkmf：

locate mkmf

或安装 ruby​​ 1.9.1 的开发版本：

sudo apt-get install ruby1.9.1-dev

我建议使用 RVM 安装 rubies：https ://rvm.io/

您也可以尝试更改 Gemfile 中的源

source 'https://rubygems.org'

而不是 :gemcutter
