nodejs中package main配置require引用失败

###packapge内容 { "main" : "./lib/interface.js" } ###lib/interface.js内容 var name; exports.setName=function(tname){ name=tname; }

       exports.sayHello=function(){
       console.log("hello  "+name);
       }

###getmodule.js内容为 var myModules=require('./somepackage'); myModules.setName("ddsoma"); var myModules1=require('./somepackage'); console.log(myModules1); myModules1.setName('neko123'); myModules.sayHello(); myModules1.sayHello(); 执行node getmodule.js报错 cannot find module './somepackage'
