meteor - 如何在流星中使用child_process.fork

我测试流星中的代码。有一些错误。

/server/lib/Test.js

Test = {
    say:function(){
        console.log("hello world");
    }
}

/server/main.js

Meteor.startup(function(){
    Test.say();  //work well 
    var path = Npm.require('path');
    var base = path.resolve('.');
    var n = Npm.require('child_process').fork(base+"/app/server/children.js");
    n.on('message', function(m) {
      console.log('PARENT got message:', m);
    });
    n.send({ hello: 'world' });
});

/server/children.js

process.on('message', function(m) {
  Test.say();   //throw a error . The Test is undefined
  console.log('CHILD got message:', m);
  process.send({name:"ABC"});
});

process.send({ foo: 'bar' });

错误：

在“/app/server/children.js”中未定义测试对象，这在main.js中是正常的。为什么？我忘了什么吗？任何帮助表示赞赏。
