Rails 3错误:没有这样的文件加载 - 初始化程序(LoadError)

Question

我在Ubuntu上,我的应用程序是为Rails 2.3.5编写的,我让它在2.3.10上运行但是当我升级到Rails 3.0.3并尝试使用"ruby script/server"运行它时,它会抛出这个错误.

/usr/local/lib/site_ruby/1.8/rubygems.rb:230:in `activate': can't activate rails (= 2.3.10, runtime) for [], already activated rails-3.0.3 for [] (Gem::LoadError)
        from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:35:in `require'
        from /home/bob/savage/config/boot.rb:55:in `load_initializer'
        from /home/bob/savage/config/boot.rb:38:in `run'
        from /home/bob/savage/config/boot.rb:11:in `boot!'
        from /home/bob/savage/config/boot.rb:110
        from script/server:2:in `require'
        from script/server:2

当我卸载Rails 2.3.10时,它会抛出此错误

bob@ubuntu:~/test.2.3.10$ ruby script/server
/usr/local/lib/site_ruby/1.8/rubygems.rb:777:in `report_activate_error': RubyGem version error: rails(3.0.3 not = 2.3.10) (Gem::LoadError)
        from /usr/local/lib/site_ruby/1.8/rubygems.rb:211:in `activate'
        from /usr/local/lib/site_ruby/1.8/rubygems.rb:1056:in `gem'
        from /home/bob/test.2.3.10/config/boot.rb:60:in `load_rails_gem'
        from /home/bob/test.2.3.10/config/boot.rb:54:in `load_initializer'
        from /home/bob/test.2.3.10/config/boot.rb:38:in `run'
        from /home/bob/test.2.3.10/config/boot.rb:11:in `boot!'
        from /home/bob/test.2.3.10/config/boot.rb:114
        from script/server:2:in `require'
        from script/server:2

想法？在此先感谢您的帮助.

我得到了同样的错误,直到我意识到我仍然使用我的应用程序的2.3.10版本中相同的旧配置/ boot.rb.我进入一个干净的目录并生成一个新的Rails 3.0.3应用程序并使用它创建的boot.rb.该文件完全不同,它让我超过了这个错误.
