終端報錯:Path must be a string. Received null感覺上是 __dirname的問題，但是我改成相對路徑后還是報錯，求大神指導(dǎo)一下剛學(xué)node的小白，感激不盡~app.js下：var app = require('express').createServer(), io = require('socket.io').listen(app);app.listen(1111);app.get('/',function(req,res){ res.sendfile(__dirname+'/index.html');});io.sockets.on('connection',function(socket){ socket.emit('welcome',{text:'hello world!'})})index.html下：<!DOCTYPE html><html><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>socket.io chatting!</title> <script src="/socket.io/socket.io.js"></script></head><body> <h1>let's chatting~</h1> <script> var socket = io.connect(); socket.on('welcome',function(data){ console.log(data.text); }) </script></body></html>
用express在node.js開發(fā)一個socket.io聊天服務(wù)器，app.js出現(xiàn)的文件路徑問題
