javascript - 哈巴狗（玉）中的错误不显示布局中的内容

问题描述

大家好我最近开始哈巴狗（玉），我无法加载我的布局

这是我的layout.pug

html(lang='en')
 head
  title hi
  link(rel='stylesheet', type='text/css', href='../public/css/W3.css')     

  link(rel='stylesheet', href='https://fonts.googleapis.com/css?family=Allerta+Stencil')  
body
 div.w3-bar.w3-black
  div.w3-left.w3-margin-left
   a.w3-bar-item.w3-opacity.w3-large.w3-btn(href='#') My website template                     
   a.w3-bar-item.w3-button.w3-hover-green(href='#') Home            
   a.w3-bar-item.w3-button.w3-hover-green(href='#') Link 1
  div.w3-right.w3-margin-right
   a.w3-bar-item.w3-button.w3-hover-blue(href='#') Link 2                     
   a.w3-bar-item.w3-button.w3-hover-orange(href='#') Link          
div.w3-margin.w3-continer.w3-center
 div.w3-margin.w3-card-4.w3-continer
  p.w3-jumbo.w3-opacity(class='.w3-allerta') this is my first template                 
  p.w3-large.w3-margin welcome to Home

我用 index.pug 加载它

extends layout
block content
 h3 hello world

我用这段代码加载它

  app.get('/', function (req, res) {
  res.render('index.pug');
  });

我也用这段代码把我的css框架w3.css放在公共文件夹中

 app.use(express.static(path.join(__dirname, "public")))

我得到这个错误

Error: C:\Users\MashadService.ir\Desktop\node js\express-simple-website\views\index.pug:3:1

解决方案

layout.pug 在添加代码block content

html(lang='en')
 head
  title hi
  link(rel='stylesheet', type='text/css', href='../public/css/W3.css')     

  link(rel='stylesheet', href='https://fonts.googleapis.com/css?family=Allerta+Stencil')  
body
 div.w3-bar.w3-black
  div.w3-left.w3-margin-left
   a.w3-bar-item.w3-opacity.w3-large.w3-btn(href='#') My website template                     
   a.w3-bar-item.w3-button.w3-hover-green(href='#') Home            
   a.w3-bar-item.w3-button.w3-hover-green(href='#') Link 1
  div.w3-right.w3-margin-right
   a.w3-bar-item.w3-button.w3-hover-blue(href='#') Link 2                     
   a.w3-bar-item.w3-button.w3-hover-orange(href='#') Link          
div.w3-margin.w3-continer.w3-center
 div.w3-margin.w3-card-4.w3-continer
  p.w3-jumbo.w3-opacity(class='.w3-allerta') this is my first template                 
  p.w3-large.w3-margin welcome to Home

  block content
