【问题描述】：
尝试启动本地服务器（$ rails 服务器）但收到此消息：
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.
当我尝试运行 sudo 命令时，我收到了这条消息：
Building native extensions. This could take a while...
ERROR: Error installing rails:

我能做什么？

我猜你才刚刚起步。有一个教程“ruby.railstutorial.org/chapters/beginning#top”，我认为这对你有好处。此外，第一章是正确安装导轨和其他东西的指南。

Rails 4？您是否从回购中拉出项目？如果两者的答案都是肯定的：这是一个常见的“问题”，对于 rails 4，bin 路径需要在 repo 中提交（在以前的版本中被忽略）。如果是这种情况，只需运行 bundle --binstubs 即可重新生成垃圾箱。
