我使用的是Angular.js，我使用的是polls代码。 下面是index.jade的代码:

doctype html
 html(lang='en')
 head 
 meta(charset='utf-8')
  meta(name='viewport', content='width=device-width, initial-scale=1, user-scalable=no') 
  title= title 
  link(rel='stylesheet', href='//netdna.bootstrapcdn.com/bootstrap/3.0.1/ css/bootstrap.min.css') 
  link(rel='stylesheet', href='/stylesheets/style.css')
  script(src='//ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js') 
  script(src='//ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular-resource.min.js')
   body 
   nav.navbar.navbar-inverse.navbar-fixed-top(role='navigation')
    div.navbar-header
     a.navbar-brand(href='#/polls')= title
      div.container 
      div

在运行代码时，我得到的错误为:

2
1doctype html
>； 2 html(lang='en')
3头
4元(charset='UTF-8')
5元(name='viewport'，content='width=device-width，initial-scale=1，user-scalable=no')

意外的标记“缩进”

1| doctype html
> 2| html(lang='en')
3| head
4| meta(charset='utf-8')
5| meta(name='viewport', content='width=device-width, initial-scale=1, user-scalable=no')
unexpected token "indent"
