在OS X上升级到ruby 1.9.2后，我的rails项目失败

Question

我已经将ruby升级到1.9.2，rubygems 1.5.0并按照本教程安装了最新的rails 3.0.3：

http://hivelogic.com/articles/ruby-rails-mongrel-mysql-osx

但现在我现有的项目已不再适用。 如果我做一个“ruby脚本/关于”，我得到这个：

<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- /Users/sneigaard/work/rails/myproject/config/../vendor/rails/railties/lib/initializer (LoadError)
    from <internal:lib/rubygems/custom_require>:29:in `require'
    from /Users/sneigaard/work/rails/myproject/config/boot.rb:45:in `load_initializer'
    from /Users/sneigaard/work/rails/myproject/config/boot.rb:38:in `run'
    from /Users/sneigaard/work/rails/myproject/config/boot.rb:11:in `boot!'
    from /Users/sneigaard/work/rails/myproject/config/boot.rb:110:in `<top (required)>'
    from <internal:lib/rubygems/custom_require>:29:in `require'
    from <internal:lib/rubygems/custom_require>:29:in `require'
    from script/about:2:in `<main>'

如果我运行“mongrel_rails start”，我会收到此错误：

** Starting Mongrel listening at 0.0.0.0:3000

在脚本/服务器中我有这个：

#!/usr/bin/env ruby
require File.expand_path('../../config/boot', __FILE__)
require 'commands/server'

我搜索并搜索了网，但我无法弄明白，我的项目被卡住了:(请帮助我。

谢谢

Answer 1

是rails server发出了同样的错误吗？ 你似乎在rails 3中使用rails 2命令。还有，你的所有宝石都加载到1.9.2吗？ 切换红宝石时必须重新加载所有内容。

Answer 2

如果你打字，你的红宝石会有一些误配置

which ruby
gem environment

和

ruby -v

它是全能的吗？

我建议使用RVM非常简单，以便为您的商务设置良好的文档和有用。

似乎你的项目仍然在rails 2.3。*而不是3.0。*，在rails 3中，thear不是脚本/服务器脚本文件。 安装rvm ruby​​ 1.9.2和正确的gem到你的项目。

希望这可以帮助。

Answer 3

将应用程序从1.8.7升级到1.9.2时遇到此问题。
在Ruby 1.9.2中，Kernel.require不像1.8那样工作，而是看起来他们希望你使用Kernel.require_relative
