带有Socket.io 404错误的Node.js Express服务器 [英] Node.js Express Server with Socket.io 404 Error

问题描述

对我来说很清楚，我是一名低于平均水平的程序员，并且没有互联网上的express/socket.io服务器的实际示例.尝试加载页面时为什么会出现此错误?

It’s become clear to me that I am a below average programmer and there is no such thing as a working example of an express/socket.io server on the internet. Why am I getting this error when I try to load the page?

GET http://localhost:3700/socket.io/socket.io.js 404 (Not Found)

我在工作目录中执行了以下命令以安装express和socket.io

I executed the following command inside of my working directory to install express and socket.io

Npm install

我的package.json文件看起来像这样

My package.json file looks like this

{
    "name": "RealTimeWebChat",
    "version": "0.0.0",
    "description": "Real time web chat",
    "dependencies": {
        "socket.io": "latest",
        "express": "latest",
        "jade": "latest"
    },
    "author": "developer"
}

这创建了一个"node_modules"目录，其中有一个"socket.io"目录.

This created a "node_modules" directory, inside of which is a "socket.io" directory.

那为什么我的应用程序找不到socket.io.js文件?

So why can’t my application find the socket.io.js file?

其他相关信息，

Other relevant information, I’m working off this tutorial. I’m following it word for word.
I have a .jade file that looks like this.

!!!
html
head
    title= "Real time web chat"
    script(src='/chat.js')
    script(src='/socket.io/socket.io.js')
    body
        #content(style='width: 500px; height: 300px; margin: 0 0 20px 0; border: solid 1px #999; overflow-y: scroll;')
        .controls
            input.field(style='width:350px;')
            input.send(type='button', value='send')

诚然，我不知道什么是玉，但我只是想尝试一个简单的例子并使其运行.我学得最好.最终项目定于周日！帮助我需要一台服务器！

Admittedly, I have no idea what jade is, but I'm just trying to get a simple example up and running. I learn best as I do. Final project is due on Sunday! Help I need a server!

推荐答案

我在GitHub的尝试一下:

git clone https://github.com/hectorcorrea/intro-to-nodejs.git
cd intro-to-nodejs
npm install
npm install socket.io
node socketioDemo

然后打开两个浏览器窗口并浏览到 http://localhost:3000 ，您应该能够在两者之间交换消息.

Then open two browser windows and browse to http://localhost:3000 and you should be able to exchange messages between the two.
