NameError: 未初始化的常量 Gem::SourceIndex [英] NameError: uninitialized constant Gem::SourceIndex

问题描述

在访问主页时(在成功运行 bundle install 后)，未进行任何修改的新 Rails 应用出现此错误.

This error appears for a new rails app, with nothing modified, when visiting the homepage (after successfully running bundle install).

这里是版本号:

ruby:1.9.3p392(2013-02-22 修订版 39386)[x86_64-darwin12.2.1]

导轨:3.2.12

rvm: 1.18.14

宝石:2.0.0

捆绑器:1.3.0.pre.8

调用 which ruby​​ 返回 /Users/J/.rvm/rubies/ruby-1.9.3-p392/bin/ruby，这看起来很可疑，对吧?

Calling which ruby returns /Users/J/.rvm/rubies/ruby-1.9.3-p392/bin/ruby, which seems fishy, right?

推荐答案

需要更新Bundler:gem update bundler

You need to update Bundler: gem update bundler

RubyGems 2.0 版 似乎是触发因素对于错误:

RubyGems release 2.0 seems to be the trigger for the error:

RubyGems 2.0 包含几个新功能和许多重大更改.其中一些更改将导致现有软件崩溃....如果您使用的是 bundler，请务必安装 1.3.0.prerelease 版本或更高版本.旧版本的 bundler 不适用于 RubyGems 2.0.

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.
