我已经设置了一个 rails 应用程序，但是当我进行捆绑安装时，我收到一个错误：
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing curb (0.8.5), and Bundler cannot continue.
gem install curb -v '0.8.5'在捆绑之前确保成功。
所以我做了
gem install curb -v '0.8.5
但我不断收到此错误：

当我在我的 gem 主目录 (~/.rvm/gems/ruby-2.1.1) 中执行ls -ladg curl-*时，我收到以下错误
ls: cannot access curb-*: No such file or directory
请就如何修复 gem install 路边提出建议
