https://ruby-china.org/ytx0573 en-us <p>自己的 osx 有两个管理员，rails 命令已安装成功，但是只能在用户目录下面使用 rails 命令，一旦跑到其他地方，就无法使用。错误如下：</p> <p>Rails is not currently installed on this system. To get the latest version, simply type:</p> <p>$ sudo gem install rails</p> <p>You can then rerun your "rails" command.</p> <p>需要怎么配环境变量呢？</p> ytx0573 Thu, 11 Aug 2016 11:05:44 +0800 https://ruby-china.org/topics/30795 https://ruby-china.org/topics/30795
