未捕获的TypeError：Object＃< Object>没有方法'连接' [英] Uncaught TypeError: Object #<Object> has no method 'connect'
问题描述
所以我做了 npm install express 和 npm install socket.io 我带了 node_modules 我的服务器文件夹，我使用 WAMP 。
So I did npm install express and npm install socket.io and I brought the node_modules folders to my server folder where I am using WAMP.
将此用作 server.js ：
var app = require('express').createServer();
var io = require('socket.io').listen(app);
io.sockets.on('connection', function (socket) {
console.log('Someone connected!');
socket.on('set nickname' , function (nickname) {
socket.nickname = nickname;
console.log(nickname + ' just connected!');
});
});
app.listen(8080);
并将其用作 client.html

<script src="http://cdn.socket.io/stable/socket.io.js"></script>
<script>
var socket = io.connect('http://localhost:8080');
socket.on('connect', function () {
console.log('We are connected!');
var name = prompt('What is your name?');
this.emit('set namename', name, function (success) {
console.log('The server got the message!');
if (!success) {
console.log('Nickname is in use!');
}
});
});
</script>
</head>

我得到的错误是未捕获TypeError：对象＃<对象>没有方法'connect'
我知道我使用的不同于 socket.io.js 因为我不知道从哪里得到 /socket.io/socket.io.js 。我尝试了 node_modules / socket.io / lib / socket.io.js 这是我发现的另一个我的 node_modules 文件夹，但不是这样。
I know I used a different than socket.io.js becase I don't know where to get the /socket.io/socket.io.js. I tried doing node_modules/socket.io/lib/socket.io.js which is another one I found i my node_modules folder, but that isn't it.
我还启动了服务器，我得到了 socket.io已启动所以我知道这有效。
I also started my server and I got socket.io started so I know that works.
推荐答案
你得到的错误是因为socket.io脚本（到index.html）的来源是错误的。所以改变这个：
The error you got is because the source of socket.io script (into index.html) is wrong. So change this:
<script src="http://cdn.socket.io/stable/socket.io.js"></script>
在此：
<script src="http://localhost:3000/socket.io/socket.io.js"> </script>
是的，socket.io是根服务器目录中的文件夹，我的服务器端套接字是在港口3000上听。
And yes, socket.io is a folder into the root server directory and my server-side socket is listening on port 3000.
