// 引入readline模块
var readline = require('readline');

//创建readline接口实例
var rl = readline.createInterface({ 
 input:process.stdin,
 output:process.stdout
});

// question方法
rl.question("你叫什么？",function(answer){ 
 console.log("名字是"+answer);
 // 不加close，则不会结束
 rl.close();
});

// close事件监听
rl.on("close", function(){ 
 // 结束程序
 process.exit(0);
});
