我正在尝试运行
rails new demo
但被告知:
Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your "rails" command.
我运行该命令,然后运行许多“获取”行,然后运行许多“正在为...安装 RDoc 文档”,但最后几行说:
Installing RDoc documentation for rails-3.2.13...
file 'lib' not found
然后它停止运行,'rails' 命令(见上文)仍然无法工作。为什么没有安装 Rails?我还应该做什么?谢谢
