【问题描述】：

今天早些时候，我更新了系统上的 gems：

gem update

它更新了一些 gem，但之后我无法启动我的 rails 服务器，我收到了这个错误：

/Users/gugguson/rubys/my_rails_app/config/boot.rb:9:in `rescue in <top (required)>': uninitialized constant Bundler (NameError)
    from /Users/gugguson/rubys/my_rails_app/config/boot.rb:5:in `<top (required)>'
    from <internal:lib/rubygems/custom_require>:29:in `require'
    from <internal:lib/rubygems/custom_require>:29:in `require'
    from script/rails:5:in `<main>'

如果我创建一个新应用：

rails new test99

...然后进入文件夹并运行 rails server s 我得到这个错误：

[~/rubys/test99] rails s
<internal:gem_prelude>:168:in `load_full_rubygems_library': undefined local variable or method `path' for Gem::QuickLoader:Module (NameError)

有什么想法吗？

谢谢，约翰

【问题讨论】：

我尝试重新加载所有捆绑包，删除 bundler-1.0.10 以使用以前的版本并重新启动计算机，我有同样的错误。
您运行的是什么版本的 rubygems 和 ruby。 rubygems 1.5.x 和 ruby 1.9.1 之间存在不兼容问题。

【解决方案1】：

正如 lebreeze 所说，尝试使用 gem update --system 更新 rubygems。看起来有 some issues 并且它们已在最近的版本中得到修复。
