I am new to programming (previously only did html/css/design) trying to start learning RoR via the book Simply Rails 2. However I want to start with the most recent versions of Ruby(1.9.2) and Rails (3) so I am forced to get everything configured without the book. I have looked a lot via google and on *. When I run rails server it automatically uses Webrick, but I want to be using Mongrel. I installed the prerelease Mongrel via gem install mongrel --pre and removed the previous version. I read that in order to get Mongrel to work with rails server I had to add gem 'mongrel' to the Gemfile, but I do not know which one I should be adding it to (I tried several but nothing changed). So I decided to look at mongrel documentation via git and learned about mongrel_rails start when I run that I get this:
我是编程（以前只做html / css / design）的新手，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*在没有这本书的情况下完成所有配置。我通过谷歌和*看了很多。当我运行rails服务器时它自动使用Webrick，但我想使用Mongrel。我通过gem install mongrel --pre安装了预发布的Mongrel并删除了以前的版本。我读到为了让Mongrel与rails服务器一起工作，我不得不在Gemfile中添加gem'mongrel'，但我不知道应该将它添加到哪一个（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在我运行时开始我得到了这个：

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：在'block in setup'中：你已经启动了mongrel 1.2。 0.pre2，但你的Gemfile需要mongrel 1.1.5。考虑使用bundle exec。是关键但我无法解决它。

My best guess at this point (1am...very tired) is that I am missing a file or something is not named as it should be..maybe i need to use the :require action in my Gemfile..maybe I just need to sleep on it. Ha.
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应该是..我可能需要在我的Gemfile中使用：require action.maybe我只是需要睡在上面。哈。
Again, thanks a ton @duddle for getting me past the first error! Any more help is greatly appreciated!
再次感谢@duddle让我超越第一个错误！非常感谢任何帮助！

You have already activated mongrel 1.2. 0.pre2, but your Gemfile requires mongrel 1.1.5. Consider using bundle exec. is the key but I have not been able to solve it.
你已经激活了mongrel 1.2。 0.pre2，但你的Gemfile需要mongrel 1.1.5。考虑使用bundle exec。是关键但我无法解决它。
You were almost there!
你快到了！
gem 'mongrel', '>= 1.2.0.pre2'
The second parameter tells bundler to require a version equal to or greater than 1.2.0.pre2, which you have to use when using Ruby 1.9.2.
第二个参数告诉bundler需要一个等于或大于1.2.0.pre2的版本，在使用Ruby 1.9.2时必须使用它。

Just in case you didn't figure it out.
以防你没弄清楚。
I ran gem install 'dispatcher' and added gem 'dispatcher' in the Gemfile of my app. Then everything was fine.
我运行了gem install'dispatcher'并在我的应用程序的Gemfile中添加了gem'dispatcher'。一切都很好。
From the small experience I have with ruby, everytime I have a "require -- no such file to load" problem. It is because I am missing a specific gem.
从我对ruby的小经验来看，每次我都有“需要 - 没有这样的文件加载”的问题。这是因为我错过了一个特定的宝石。

The mongrel gem isn’t compatible with Ruby 1.9.2; you’ll have to use gem 'sho-mongrel' in its place.
mongrel gem与Ruby 1.9.2不兼容;你必须在它的位置使用宝石'sho-mongrel'。
