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

但现在我的现有项目已不再适用。如果我做一个“ruby script / about”，我明白了：

<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
** Starting Rails with development environment...

    from /usr/bin/mongrel_rails:19:in `load'
    from /usr/bin/mongrel_rails:19

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

它rails server是否吐出同样的错误？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？你必须在切换红宝石时重装一切。

Answer 2

如果你输入

，

你的ruby会有一些配置错误

which ruby
gem environment

和

ruby -v

它是全能的吗？

我建议使用RVM 设置好文档非常简单，对你的商务很有用。

似乎您的项目仍然在rails 2.3。*而不是3.0。*，在rails 3中，thear不是脚本/服务器脚本文件。将rvm ruby 1.9.2和正确的gem安装到您的项目中。

希望这可以提供帮助。

Answer 3

将应用从1.8.7升级到1.9.2时出现此问题在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它 Kernel.require_relative

请参阅此处了解可在两种红宝石中使用的解决方案

Ruby: require vs require_relative - best practice to workaround running in both Ruby <1.9.2 and >=1.9.2

在OS X上升级到ruby 1.9.2后，我的rails项目失败了
