node.js TypeError:路径必须是绝对路径或指定res.sendFile的根目录[无法分析JSON]

添加所以我的下一个问题是，当我尝试添加一个新的依赖项时(npm install --保存socket.io)。JSON文件也是有效的。我得到这个错误:无法解析json
npm ERR! Unexpected string
npm ERR! File: /Users/John/package.json
npm ERR! Failed to parse package.json data.
npm ERR! package.json must be actual JSON, not just JavaScript.
npm ERR!
npm ERR! This is not a bug in npm.
npm ERR! Tell the package author to fix their package.json file. JSON.parse 所以我一直在尝试找出为什么这个错误会返回。所有的文件(HTML、JSON、JS)都在我桌面上的同一个文件夹中。我使用的是node.js和socket.io
这是我的JS文件：
var app = require('express')();
var http = require('http').Server(app);
app.get('/', function(req, res){
res.sendFile('index.html');
});
http.listen(3000,function(){
console.log('listening on : 3000');
});下面是要返回的内容：
MacBook-Pro:~ John$ node /Users/John/Desktop/Chatapp/index.js
