使用Rails3和Ruby 1.9.2运行Mongrel的LoadError

使用Rails3和Ruby 1.9.2运行Mongrel的LoadError

teh*_*ron 17 ruby mongrel ruby-on-rails-3

我不熟悉编程(之前只做html/css/design)试图通过Simply Rails 2开始学习RoR.但是我想从最新版本的Ruby(1.9.2)和Rails(3)开始我被迫在没有这本书的情况下完成所有配置.我通过谷歌和stackoverflow看了很多.当我rails server自动运行它时使用Webrick,但我想使用Mongrel.我安装了预发布的Mongrel via gem install mongrel --pre并删除了以前的版本.我读到,为了让Mongrel与rails server我一起工作,我必须添加gem 'mongrel'到Gemfile,但我不知道我应该添加哪一个(我尝试了几个但没有改变).所以我决定通过git查看mongrel文档并了解mongrel_rails start我何时运行,我得到了这个:

我最好的猜测是 C:/Ruby192/lib/ruby/gems/1.9.1/gems/bundler-1.0.0.rc.6/lib/bundler/runtime.rb:27:in 'block in setup': You have already activated mongrel 1.2. 0.pre2, but your Gemfile requires mongrel 1.1.5. Consider using bundle exec.关键,但我无法解决它.

我会感激任何帮助,以便我可以继续学习语言!

编辑:由于@duddle,我能够克服上述问题,但现在我有另一个问题......我收到此错误:

我在这一点上最好的猜测(凌晨1点......非常累)是我错过了一个文件或者没有命名的东西,因为它应该是..我可能需要:require在我的Gemfile中使用该动作.可能我只需要睡觉在上面.哈.

再次感谢@duddle让我超越第一个错误!非常感谢任何更多的帮助!
