I am using the most up to date version of Socket.IO and I'm trying the first example on the how to use page, however, I'm getting an error when I try to get to '/socket.io/socket.io.js'
我正在使用最新版本的 Socket.IO 并且我正在尝试有关如何使用页面的第一个示例，但是，当我尝试访问 '/socket.io/socket. io.js'
The javascript console saying the file doesn't exist. When I check my browser (both http://socket.io/socket.io.jsand https://socket.io/socket.io.js), it isn't up there either. Is the documentation out of date? Where is the socket.io.js file that I'm supposed to include?
javascript 控制台说该文件不存在。当我检查我的浏览器（http://socket.io/socket.io.js和https://socket.io/socket.io.js）时，它也不在那里。文档是否过时？我应该包含的 socket.io.js 文件在哪里？
I am running this on a Mac with NodeJS running my app.js server.
我在 Mac 上运行它，NodeJS 运行我的 app.js 服务器。
I've tried using "http://cdn.socket.io/stable/socket.io.js" but it seems that is an old version (0.6) and the Javascript console says it doesn't have the "connect" function. (which is weird, I would think that connect is a rather integral function to have in such a library, but I guess not)
我试过使用“ http://cdn.socket.io/stable/socket.io.js”但它似乎是一个旧版本（0.6）并且Javascript控制台说它没有“连接”功能. （这很奇怪，我认为 connect 是这样一个库中一个相当完整的功能，但我想不是）

Your Socket.IO server will handle serving the correct version of the Socket.IO client library; you should not be using one from elsewhere on the Internet. From the top example on the Socket.IO website:
您的 Socket.IO 服务器将处理提供正确版本的 Socket.IO 客户端库；你不应该使用互联网上其他地方的。来自Socket.IO 网站上的顶部示例：
<script src="/socket.io/socket.io.js"></script>
This works because you wrap your HTTP server in Socket.IO (see the example at How To Use) and it intercepts requests for /socket.io/socket.io.jsand sends the appropriate response automatically.
这是有效的，因为您将 HTTP 服务器包装在 Socket.IO 中（请参阅如何使用中的示例），它会自动拦截请求/socket.io/socket.io.js并发送适当的响应。

I know this seems obvious, but did you install Socket.IO on your server? Then you'll get a local copy of the file at '/socket.io/socket.io.js'.
我知道这看起来很明显，但是您是否在服务器上安装了 Socket.IO？然后，您将在“/socket.io/socket.io.js”处获得文件的本地副本。
npm install socket.io
