子進(jìn)程child.js：setInterval(function(){console.log(1);},2000);父進(jìn)程：constfs=require('fs');constout=fs.openSync('a.txt','a');consterr=fs.openSync('b.txt','a');constp=require('child_process').spawn('node',['child.js','a','b'],{'stdio':['ignore',out,err],'detached':true});p.unref();設(shè)置了spawn方法的參數(shù)'stdio':['ignore',out,err]和'detached':true后，子進(jìn)程一直運(yùn)行，關(guān)閉父進(jìn)程的終端或者關(guān)閉IDE都不能終止，怎么辦？
