Given:
考虑到:
- A rails 2.3.x application currently being upgraded to rails 3.
- rails 2.3。x应用程序目前正在升级到rails 3。
- Upgrading ruby from 1.8.7 to 1.9.2
- 将ruby从1.8.7升级到1.9.2
- The rails app WAS using mongrel as the web server for development.
- rails应用程序使用mongrel作为web服务器进行开发。
- A new fresh install of Ubuntu 10.10 Netbook remix.
- 全新安装的Ubuntu 10.10上网本remix。
- I forgot to install mongrel before starting the upgrade so...
- 我在开始升级之前忘记安装了mongrel，所以……
The Problem:
存在的问题:
After updating some code so that delayed job is working, I go to run rails s and I realize that I'm running WEBrick. I install mongrel: gem install mongrel --pre for the 1.9.2 version and run rails s again. Its still using WEBrick, which wasn't the expected behavior. Before, I would just install mongrel and rails would know that I wanted mongrel instead.
在更新了一些代码以使延迟的作业正常工作之后，我运行rails s并意识到我正在运行WEBrick。我安装了mongrel: gem安装了mongrel——为1.9.2版本预安装，并再次运行rails s。它仍然在使用WEBrick，这不是预期的行为。在此之前，我只需要安装mongrel和rails就可以知道我想要的是mongrel。
Also, I'm getting this error when WEBrick runs... it starts and then errors and shuts down. (maybe due to upgrading or... maybe WEBrick doesn't like ruby 1.9.2?):
而且，当WEBrick运行时，我得到了这个错误……它开始，然后出错，然后关闭。(可能是升级或…)也许WEBrick不喜欢ruby 1.9.2?)
=> Booting WEBrick
=> Rails 3.0.5 application starting in development on http://0.0.0.0:3000

=> Ctrl-C to shutdown server

It will be better if you add
如果你加上去会更好
group :development do
gem :mongrel
end
Cause you dont need it in production
因为你在生产中不需要它
#2

You need to add gem "mongrel" to your Gemfile and run bundle install
您需要将gem“mongrel”添加到Gemfile并运行bundle安装
#3

Just remember that when you add gem "mongrel" to the Gemfile, you'll need to specify:
请记住，当您将gem“mongrel”添加到Gemfile时，您需要指定:
gem "mongrel", "1.2.0.pre2"
Newer versions of mongrel are not compatible with Rails 3.
新版本的mongrel与Rails 3不兼容。

Alternatively, if you don't want mongrel, my understanding is that you can just comment out the offending line in new_rails_defaults.rb. The error message goes away for me when I do this.
或者，如果您不想要mongrel，我的理解是您可以注释掉new_rails_default .rb中的违规行。当我这样做时，错误信息就会消失。

Try usinggem install mongrel --pre
尝试使用gem安装mongrel -pre
It worked for me!!!
