Rails 3.0 Mongrel问题

Question

好了，伙计们，事实是我正在致力于将一个应用程序移植到justhost.com上，因为我还买不起自己的服务器。无论哪种方式，我一直在mongrel.log中收到这个错误，但没有得到任何关于这个错误的含义或如何修复它的帮助。

/usr/lib/ruby/gems/1.8/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:239:in require': no such file to load -- dispatcher (LoadError) from /usr/lib/ruby/gems/1.8/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:239:in需要来自/usr/lib/ruby/gems/1.8/gems/activesupport-3.0.0/lib/active_support/dependencies的“from /usr/lib/ruby/gems/1.8/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:225:in load_dependency' from /usr/lib/ruby/gems/1.8/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:591:innew_constants_in”.rb:225:in load_dependency' from /usr/lib/ruby/gems/1.8/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:239:in需要来自/usr/lib/ruby/.rb:225:in/load_dependency' from /usr/lib/ruby/gems/1.8/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:239:in/1.8/gems的/usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/configurator.rb:149:in call' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/configurator.rb:149:inlistener中的‘from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/rails.rb:148:in rails' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/mongrel_rails:113:incloaker_’/mongrel-1.1.5/bin/mongrel_rails:99:在cloaker_' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/configurator.rb:50:in调用‘从/usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/configurator.rb:50:in新建’从/usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/mongrel_rails:84:in run' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/command.rb:212:in运行‘从/usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/mongrel_rails:281 from /usr/bin/mongrel_rails:19:in ` `load‘from /usr/bin/mongrel_rails:19

我不认为这与我的应用程序的设置有任何关系，但我也是Rails的新手。如果有人知道如何解决这个问题，或者我可能做错了什么，我将不胜感激。提前感谢！

Answer 1

我调查了一下这个。由于JustHost使用cPanel，因此cPanel目前不支持Rails3。

Answer 2

我不知道你是否仍然对答案感兴趣，但当我试图在我的rails3应用程序中使用mongrel_rails启动命令启动mongrel时，我遇到了同样的错误。

但当我在你的应用程序的脚本文件夹中使用rails服务器启动它时，它就起作用了。如果混合gem在Gemfile中，运行rails服务器将启动mongrel而不是WEBrick。

你会在here上找到更多信息。

希望这能有所帮助！
