我在 Rails 控制台中输入开始工作并收到以下错误：

MacBook-Pro:blog agreiner$ rails console

几天前我开始使用 Rails，所以我分析错误的能力仅限于我的谷歌能力。我没有找到任何关于Could not find gem 'rails(=3.0.0beta3) ruby

谁能指出我正确的方向？

看起来 rails gem 是在某个时候安装的，但后来只是部分卸载了，或者安装在了一个意外的位置。第一步是尝试重新安装。我不确定您使用的是系统 ruby​​，还是通过 rvm/ruby-build 安装的系统，所以很难给出比这更多的建议。

它找不到您的 Rails 宝石。先试试：
