Question

我仍然是Rails和Ruby的新手 - 在升级到新版本的Ubuntu（11.04）后，我的rails安装无法正常工作。我已经尝试更新Rails，并更新我使用RVM安装的版本，但没有一个工作。

这是终端输出：

 /usr/share/rails-ruby1.8/railties/lib/rails_generator/options.rb:32:in `default_options': undefined    method `write_inheritable_attribute' for Rails::Generator::Base:Class (NoMethodError)
    from /usr/share/rails-ruby1.8/railties/lib/rails_generator/base.rb:90:in `<class:Base>'

    from <internal:lib/rubygems/custom_require>:29:in `require'
    from /usr/share/rails-ruby1.8/railties/bin/rails:14:in `<main>'

从那以后，我特意尝试更新铁路，但这也不起作用。自从我第一次收到错误以来，输出没有改变。

问题是导轨恢复到2.3.5。我不得不卸载rails并设置一个gemset，如下所述：Every time I close terminal rails defaults back to 2.3.5 from 3.0.3?

我建议你看看RVM。它是迄今为止在* NIX平台上管理Ruby和Rails安装的最佳方式。

升级到Ubuntu 11.04后Rails坏了
