ruby-on-rails - NameError:未初始化的常量Gem::SourceIndex

Question

在访问首页时(成功运行bundle install之后)，对于新的Rails应用程序，未进行任何修改，就会出现此错误。

这是版本号:
ruby: 1.9.3p392 (2013-02-22 revision 39386) [x86_64-darwin12.2.1]rails: 3.2.12rvm: 1.18.14gem: 2.0.0bundler: 1.3.0.pre.8
调用which ruby会返回/Users/J/.rvm/rubies/ruby-1.9.3-p392/bin/ruby，这似乎很糟糕，对吗？

Answer 1

您需要更新Bundler:gem update bundler
RubyGems发布2.0 seems to be the trigger错误:

RubyGems 2.0 includes several new features and many breaking changes. Some of these changes will cause existing software to break. . . . If you are using bundler be sure to install a 1.3.0.prerelease version or newer. Older versions of bundler will not work with RubyGems 2.0.

这是 issue details。
