ruby - gem install mongrel 使用 ruby​​ 1.9.1 失败

Question

我昨天开始接触 Rails 开发。
我安装了 ruby​​ 1.9.1、rubygems 和 rails。
运行 gem install mongrel 运行良好并且表面上也安装了 mongrel。我有点困惑，因为:

• 脚本/服务器默认启动webrick
• which mongrel 什么都不返回
• locate mongrel 返回很多条目，例如

/Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel.../usr/local/bin/mongrel_rails/usr/local/lib/ruby/gems/1.9.1/cache/mongrel-1.1.5.gem/usr/local/lib/ruby/gems/1.9.1/doc/actionpack-2.3.2/rdoc/files/lib/action_controller/vendor/rack-1_0/rack/handler/evented_mongrel_rb.html/usr/local/lib/ruby/gems/1.9.1/doc/actionpack-2.3.2/rdoc/files/lib/action_controller/vendor/rack-1_0/rack/handler/mongrel_rb.html/usr/local/lib/ruby/gems/1.9.1/doc/actionpack-2.3.2/rdoc/files/lib/action_controller/vendor/rack-1_0/rack/handler/swiftiplied_mongrel_rb.html/usr/local/lib/ruby/gems/1.9.1/gems/actionpack-2.3.2/lib/action_controller/vendor/rack-1.0/rack/handler/evented_mongrel.rb/usr/local/lib/ruby/gems/1.9.1/gems/actionpack-2.3.2/lib/action_controller/vendor/rack-1.0/rack/handler/mongrel.rb/usr/local/lib/ruby/gems/1.9.1/gems/actionpack-2.3.2/lib/action_controller/vendor/rack-1.0/rack/handler/swiftiplied_mongrel.rb/usr/local/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5...

看起来我安装了 mongrel(默认安装和我的自定义安装)。那么为什么 which mongrel 不返回一些东西。

同时尝试使用 gem install mongrel 重新安装 mongrel 返回抛出它自己的一组异常:

您可以使用 sudo gem install mongrel --pre 安装 mongrel 1.2 prerelease:

$ sudo gem1.9 install mongrel --pre> Building native extensions.  This could take a while...> Successfully installed mongrel-1.2.0.pre2> 1 gem installed
