让 socket.io 在 Windows 7 x64 位平台上工作

Question

在 Express 3.x 上的 Windows 7 x64 位环境中安装 socket.io 包给我带来了很大的困难。

我不得不理清几十个或编译错误，我不得不安装以下Windows 7包安装过程输出没有错误：

• Cygwin C++ 编译器
• Cygin C++ 额外库
• Microsoft Visual Studio 2010 Express
• Microsoft .NET Framework v2.0
• Microsoft 性能工具包 Microsoft Windows SDK 7.1
• 适用于 Windows SDK 7.1 的 Microsoft Visual C++ 2010 SP1 编译器更新。

（Visual Studio 编译器给我一个警告 C4267（见下文））

尽管安装正确，我仍然有客户端错误：

Error: io is not defined
var socket = io.connect('/');

我遵循了socket.io.js 的建议，由 nodejs 服务器使用 app.js 提供服务：

var express = require('express')
    , http = require('http');

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

jade 文件中的客户端声明是：

script(src='/socket.io/socket.io.js')

我的 socket.io 客户端脚本部分是：

var socket = io.connect('/');

socket.io 安装在node-login 目录中，这是我的app/public 和app/server 目录所在的位置。

为什么客户端找不到socket.io.js？

Answer 1

在这里回答：https://github.com/LearnBoost/socket.io/issues/944

改变这个

var server = http.createServer(app);

进入这个

var server = http.createServer(app).listen( 3000 );

另外，我真的很惊讶您安装它时如此痛苦。我同意在 windows 上安装各种与 web 相关的东西比在 linux 上更痛苦，但是 node 和它附带的所有软件包不是其中之一。至少我对它没有任何问题，简单的安装，然后通过nmp 进行包管理，就像在 linux 上一样简单。
