ruby-on-rails - Rails 3错误: no such file to load -- initializer (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，它会抛出此错误。

/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？预先感谢您的帮助。

我遇到了同样的错误，直到我意识到我仍在使用 2.3.10 版本的应用程序中相同的旧 config/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，它让我克服了这个错误。
