找不到Socket.io.js(node.js + express + socket.io) [英] Socket.io.js not found (node.js + express + socket.io)

问题描述

我一直在检查其他相关答案，例如:

I've been checking other related answers such as:

• ​​ node.js/socket.io/socket.io找不到.js
• Socket.io未由Node.js服务器提供
• 在客户端上找不到socket.io.js
• 配置最简单的" node.js + socket.IO + Express服务器

• node.js /socket.io/socket.io.js not found
• Socket.io not being served by Node.js server
• socket.io.js not found on client
• Configuring 'simplest' node.js + socket.IO + Express server

但是我没有找到解决问题的方法.

But I didn't find the solution to my problem.

这正是我所做的:

通过Windows可执行文件安装节点，然后:

Installed node through the windows executable and then:

express node6 --hogan --ejs 
cd node6
npm install
npm install socket.io

npm start

我的app.js是默认应用程序，但是我添加了以下几行将其与socket.io链接:

My app.js is the default one but I added the following lines to link it with socket.io:

var http = require('http');
var server = http.createServer(app);
var io = require('socket.io')(server);
io.listen(http);
http.listen(3000);

这是完整的app.js文件.

我还尝试复制并粘贴 Node http server 和使用Express 3/4 或详细的 ，但是当调用npm start时，它们都抛出错误.

I also tried to copy and paste the examples for Node http server and Using with Express 3/4 or the app.js detailed in the socket.io docs, but both of them throw errors when calling npm start.

然后，在我的Hoggn视图中，我试图以这种方式加载socket.io:

Then, in my hoggn view, I'm trying to load socket.io this way:

<script type="text/javascript" src="/socket.io/socket.io.js"></script>

据我所知，node.js应该自动获取它，但就我而言不是.为什么? 速成版:4.2.0

As far as I know, node.js should get it automatically, but it doesn't in my case. Why? Express version: 4.2.0

这是错误页面:

推荐答案

不是执行npm install socket.io，而是必须执行npm install socket.io --save，以便将socket.io模块安装在Web开发文件夹中(在基本位置运行此命令)位置/您的index.html或index.php所在的位置).这样会将socket.io安装到运行该命令的区域，而不是全局安装到该区域，此外，它还会自动更正/更新您的package.json文件，以便node.js知道它在那里.

Instead of doing npm install socket.io you have to do npm install socket.io --save so the socket.io module gets installed in your web development folder (run this command at the base location/where your index.html or index.php is). This installs socket.io to the area in which the command is run, not globally, and, in addition, it automatically corrects/updates your package.json file so node.js knows that it is there.

然后将源路径从'/socket.io/socket.io.js'更改为'http://' + location.hostname + ':3000/socket.io/socket.io.js'.

Then change your source path from '/socket.io/socket.io.js' to 'http://' + location.hostname + ':3000/socket.io/socket.io.js'.
