ruby-on-rails-3 - 为什么 Rails & Bundler 包消失了？

Question

我正在关注 Michael Hartl 的 Ruby on Rails 教程，一切正常，直到我到达 this stage .

出于某种原因，当我尝试运行 bundle 程序或 rails 命令时，它说它们没有安装，即使它们之前正在工作并且我试图重新安装它们。

这可能与我的 rvm gemset 有关吗？我不确定如何检查 rvmrc 文件。

或者可能与我的操作系统有关。我正在 Windows 7 中托管的虚拟盒子上开发 ubuntu 12.10。

在此先感谢您的帮助。

如果这里有帮助，请点击 repo为应用程序。

看来你错过了last step of rvm install section of the tutorial :

$ rvm use 1.9.3@rails3tutorial2ndEd --create --default
Using /Users/mhartl/.rvm/gems/ruby-1.9.3 with gemset rails3tutorial2ndEd
