我从下往上安装了所有内容，并认为它运行良好，直到我运行bundle install
有没有人见过这个？有任何想法吗？请帮忙。感谢。
bundle install

不建议将Ruby 1.9.1与Rails一起使用。更好的1.8.7或1.9.2，请参阅http://rubyonrails.org/download。看起来你使用的是Debian / Ubuntu Ruby。 1.8.7在Debian / Ubuntu中可用并可用，通过apt安装ruby-full元数据包。或直接编译Ruby 1.9.2或通过Ruby版本管理器（rvm）编译。不要通过apt。

如果从源代码安装Ruby 1.9.2-x，它仍会将gem安装到/usr/local/lib/ruby/gems/1.9.1 / ...这有点像WTF（{{3} }）。我也遇到此错误，但也可能是由权限问题引起的。因此，请尝试以root身份再次运行该命令（假设您在* nix系统上遇到此问题）。是的，这并不理想，但是你可能会觉得它很有效，至少你可以继续着手解决问题（而且无论如何都在测试VM中，对吧？）。
