在express應用程序中獲取錯誤「bodyParser.json不是函數」

Question

我是nodejs的新手。在用快遞實驗時，我卡住了。我只是想測試我的應用程序。運行server.js文件時出現錯誤。我錯過了什麼？

下面是控制檯看起來像......

C:\Users\rupindersingh\Dropbox\Works\worthlessmongo>node server.js 
C:\Users\rupindersingh\Dropbox\Works\worthlessmongo\server.js:12 
app.use(bodyParser.json()); 
       ^

TypeError: bodyParser.json is not a function 
    at Object.<anonymous> (C:\Users\rupindersingh\Dropbox\Works\worthlessmongo\server.js:12:20) 
    at Module._compile (module.js:409:26) 
    at Object.Module._extensions..js (module.js:416:10) 
    at Module.load (module.js:343:32) 
    at Function.Module._load (module.js:300:12) 
    at Function.Module.runMain (module.js:441:10) 
    at startup (node.js:139:18) 
    at node.js:974:3 

這裏是pakage.json文件下

{ 
    "name": "worthlessmongo", 
    "version": "1.0.0", 
    "description": "Just Tryin", 
    "main": "server.js", 
    "scripts": { 
    "test": "echo \"Error: no test specified\" && exit 1", 
    "start": "node server.js" 
    }, 
    "author": "", 
    "license": "ISC", 
    "dependencies": { 
    "body-parser": "^1.15.2", 
    "ejs": "^2.5.2", 
    "express": "^4.14.0", 
    "mongojs": "^2.4.0" 
    }, 
    "devDependencies": {} 
} 

Server.js文件中給出：

var express=require('express'); 
var path=require('path'); 
var bodyParser=('body-parser'); 

var index=require('./routes/index'); 

var app=express(); 
app.set('views',path.join(__dirname,'views')); 
app.set('view engine','ejs'); 
app.engine('html',require('ejs').renderFile); 
app.use(express.static(path.join(__dirname,'client'))); 
app.use(bodyParser.json()); 
app.use(bodyParser.urlencoded({extended:false})); 
app.use('/',index); 
app.listen(3000,function(){ 
    console.log('server started at port 3000'); 
});

你在需要身體分析器時未使用require

var express=require('express'); 
var path=require('path'); 
var bodyParser= require('body-parser');
