把我的 ROR 代码部署到了 Linux 上去，需要安装的东西都安装好了，执行./bin/rails s，服务器可以启动，访问的时候发现页面报错为：

Internal Server Error

(<unknown>): found a tab character that violate intendation while scanning a plain scalar at line 5 column 20
WEBrick/1.3.1 (Ruby/2.1.2/2014-05-08) at democodes.com:3000

命令行的反馈是：

看看是不是 secrets.yml 里面哪里把 tab 当成空格了。要是用 vim 就:/s\t查找。
