Question

当我打开 mozilla 开发者工具时出现以下错误：

现在这个错误阻止我实现我自己的 css 样式。我正在使用 EJS 制作这个网站。这是我的后端的样子：

const express = require('express');
const bodyParser = require('body-parser');
const ejs = require('ejs');
//Step 1
const mongoose = require('mongoose');
const _ = require('lodash');

const homeContent = "Lacus vel facilisis volutpat est velit egestas dui id ornare. Semper auctor neque vitae tempus quam. Sit amet cursus sit amet dictum sit amet justo. Viverra tellus in hac habitasse. Imperdiet proin fermentum leo vel orci porta. Donec ultrices tincidunt arcu non sodales neque sodales ut. Mattis molestie a iaculis at erat pellentesque adipiscing. Magnis dis parturient montes nascetur ridiculus mus mauris vitae ultricies. Adipiscing elit ut aliquam purus sit amet luctus venenatis lectus. Ultrices vitae auctor eu augue ut lectus arcu bibendum at. Odio euismod lacinia at quis risus sed vulputate odio ut. Cursus mattis molestie a iaculis at erat pellentesque adipiscing.";
const aboutContent = "Hac habitasse platea dictumst vestibulum rhoncus est pellentesque. Dictumst vestibulum rhoncus est pellentesque elit ullamcorper. Non diam phasellus vestibulum lorem sed. Platea dictumst quisque sagittis purus sit. Egestas sed sed risus pretium quam vulputate dignissim suspendisse. Mauris in aliquam sem fringilla. Semper risus in hendrerit gravida rutrum quisque non tellus orci. Amet massa vitae tortor condimentum lacinia quis vel eros. Enim ut tellus elementum sagittis vitae. Mauris ultrices eros in cursus turpis massa tincidunt dui.";
const contactContent = "Scelerisque eleifend donec pretium vulputate sapien. Rhoncus urna neque viverra justo nec ultrices. Arcu dui vivamus arcu felis bibendum. Consectetur adipiscing elit duis tristique. Risus viverra adipiscing at in tellus integer feugiat. Sapien nec sagittis aliquam malesuada bibendum arcu vitae.

const app = express();

//Step 3
const postSchema = {
  title: String,
  bodyContent: String
};
//Step 4
const Post = mongoose.model('Post', postSchema);

app.set('view engine', 'ejs');

app.use(bodyParser.urlencoded({extended: true}));
app.use(express.static("public"));

//Step 2
//The localhost is by default
mongoose.connect('Your own mongodb database', {useNewUrlParser: true, useUnifiedTopology: true});

app.get("/", function(req,res){
  //Step 7
  Post.find({}, function(err, posts){
    res.render('home', {
      homeContent: homeContent,
      posts: posts
    });
  });
});

app.get('/about', function(req,res){
  res.render('about', {aboutContent: aboutContent});
});

app.get('/contact', function(req,res){
  res.render('contact', {contactContent: contactContent});
});

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

app.get('/post/:postId', function(req,res){
  const urlDataParam = req.params.postId;

  //Step 8
  Post.findOne({_id: urlDataParam}, function(err, post){
    res.render('post', {
      title: post.title,
      content: post.bodyContent
    });
  });
});

app.post('/compose', function(req,res){
  //Step 5
  const post = Post({
    title: req.body.postTitle,
    bodyContent: req.body.postBody
  });
  //Step 6
  post.save(function(err){
    if(err){
      return console.log(err);
    }else{
      res.redirect('/');
    }
  });
});

app.listen(1000, function(){
 console.log('The server is starting at port 1000');
});

这是我的文件结构的样子：

我在头文件中使用 boostrap，如下所示：

<!DOCTYPE html>
<html>

<head>
  <title>Daily Blog</title>
  <meta charset="utf-8">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
  <link rel="stylesheet" href="/css/style.css">
</head>

  <body>
    <nav class="navbar navbar-default">
      <div class="container">
        <div class="navbar-header">
          <p class="navbar-brand">DAILY BLOG</p>
        </div>
          <ul class="nav navbar-nav navbar-right">
            <!-- 6 -->
            <li id="home"><a href="/">HOME</a></li>
            <li id="about"><a href="/about">ABOUT US</a></li>
            <li id="contact"><a href="/contact">CONTACT US</a></li>
          </ul>
      </div>
    </nav>
    <div class="container">

任何帮助将不胜感激。
