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

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，但我一直在互联网上搜索，似乎无法找到答案。

完美解决了 Gem:Module (NoMethodError) 的未定义方法 `source_index'的问题，只有简单的行

gem update --system 1.8.25

好的，我整天都在搞砸这个问题，最后通过以下方式让事情对我有用：

  1. 更新 RVM

    rvm 得到头

  2. 将 ruby​​ 版本更改为 1.9.3

    • 在 Gemfile 中更新
    • 更新 .rvmrc 文件

  3. 将 Rails 更新到最新的 2.3 版本

    • 在 Gemfile 中更新
    • 在environments.rb中更新

做了所有然后运行

bundle exec rake db:migrate

Rails 2.3 与最新的 ruby​​ gems 和未知的 x 因素发生了一些奇怪的冲突，这可能包括 ruby​​ 1.9.1 和 1.9.2 中的问题？

这：Gem:Module (NoMethodError) 的未定义方法 `source_index' 说

Gem.source_index 已经被弃用了一段时间，但由于 Rails 2.3 除了关键的安全补丁之外没有任何更新，这永远不会得到修复。RubyGems v2.0 最终删除了该方法。降级到 2.0.0 之前的任何 ruby​​gems 版本，例如 1.8.25 以暂时恢复功能。

所以我现在的猜测是它与 Rails 2.3 与当前的 RubyGems 冲突有关。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。

没有什么不同，只是分享我的发现。

将您的宝石更新到 1.8.25

gem update --system 1.8.25

这可能会对您有所帮助。

从ApiDock：

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

在这个问题中，使用了 Rails 版本 2.3.17，并且由于被弃用，它给出了一个错误。如果是 2.3.8，它可以工作。
