我正在尝试运行bundle exec rake db:migrate，然后遇到以下错误。

bundle exec rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!

这是遇到错误的部分：

    def self.add_frozen_gem_path
      @@paths_loaded ||= begin
        source_index = Rails::VendorGemSourceIndex.new(Gem.source_index)
        Gem.clear_paths
        Gem.source_index = source_index
        # loaded before us - we can't change them, so mark them
        Gem.loaded_specs.each do |name, spec|
          @@framework_gems[name] = spec
        end
        true
      end
    end

我知道这似乎是基本的，但我一直在网上搜索，似乎无法找到答案。

问题是完全解决undefined method `source_index' for Gem:Module (NoMethodError)只有简单的行

gem update --system 1.8.25

答案 1 :(得分：1)

这：undefined method `source_index' for Gem:Module (NoMethodError) 说

  

Gem.source_index已被弃用了一段时间，但自Rails 2.3以来   除了关键安全补丁之外，没有获得任何更新   永远不会得到修复RubyGems v2.0最终删除了该方法。下坡   到2.0.0之前的任何rubygems版本，如1.8.25获得   功能现在回来了。

所以我现在的猜测是Rails 2.3与当前的RubyGems冲突。 我这样做了：

  1. gem install ruby​​gems-update -v'1.8.25'
  2. gem uninstall ruby​​gems-update＃并删除了其他版本。

    3. 没有什么区别，只是分享我的发现。

答案 2 :(得分：1)

好的，我一直在搞乱这一天，最后通过以下方式为我工作：

  1. 使RVM保持最新状态

    rvm get head

  2. 将ruby版本更改为1.9.3

    • Gemfile中的更新
    • 更新.rvmrc文件

  3. 将Rails更新到最新的2.3版本

    • Gemfile中的更新
    • 在environment.rb中更新

    4. 然后所有这些都运行了

    捆绑exec rake db：migrate

    在Rails 2.3中发生了一些奇怪的冲突，其中包含最新的ruby gems和一个未知的x因子，其中可能包含ruby 1.9.1和1.9.2中的问题？

答案 3 :(得分：0)

来自ApiDock：

  

此类已弃用或在最新的稳定版本上移动。该   此处显示了最新的现有版本（v2.3.8）。

在问题中，使用了Rails版本2.3.17，并且由于被弃用，它会出错。如果它是2.3.8，它可以工作。

答案 4 :(得分：0)

将宝石更新为1.8.25 

gem update --system 1.8.25

This可能对您有帮助。
