使用Node.js导出模块时出错

I have an issue with exporting a module in Node.js. Here is a part of my code:

我在Node.js中导出模块时遇到问题。这是我的代码的一部分：

var zmq = require('zmq');
var module = require('module');

var DeviceRequester = function(port, name)
{
   ...   
};

var SMValueGetter = function(socket)
{
   ...
};

module.exports.DeviceRequester = DeviceRequester;
module.exports.SMValueGetter = SMValueGetter;

When I use it I get the following error:

当我使用它时，我收到以下错误：

module.exports.DeviceRequester = DeviceRequester;
                           ^
TypeError: Cannot set property 'DeviceRequester' of undefined
at Object.<anonymous> (<PROJECT_PATH>/node_modules/lse/lib/lse.js:168:32)
at Module._compile (module.js:456:26)
at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)

at Object.<anonymous> (<PROJECT_PATH>/server.js:6:13)
at Module._compile (module.js:456:26)
at Object.Module._extensions..js (module.js:474:10)

I have no idea why it occurs. I've red the Node.js documentation and some tutorials about exporting modules and all of them do it that way. Am I overlooking something?

我不知道为什么会这样。我已经重新编写了Node.js文档和一些关于导出模块的教程，所有这些都是这样做的。我忽略了什么吗？

TypeError: Cannot set property 'DeviceRequester' of undefined

TypeError：无法设置未定义的属性“DeviceRequester”

at line var module=require("module"); you are overwriting the default module variable.

at line var module = require（“module”）;您正在覆盖默认模块变量。

simple try to change at something that makes more sense, such as

简单地尝试改变更有意义的东西，例如

var MyModule=require(..path..)

var MyModule = require（.. path ..）
