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.

当你下载安装了一个最新的ruby, 却发现会出现诸多问题,首先就是无法安装rails. 似乎百度谷歌怎么都找不到答案,在这个时候你只要把这个ruby 卸载掉, 改用上一个或再上一个版本的ruby, 就可以run: gem install rails 了.

截止目前, 3.3.0 和3.2.3 这两个新版本都无法安装rails
