node.js data值为空运行不了

Question

代码如下

const fs = require("fs");
const stringify = require("csv-stringify");

const data =[]

//创建转换流
const stringifier = stringify({
    delimiter:',',
    record_delimiter:"windows"
});

//有可读数据实逐行处理
stringifier.on("readable",()=>{
    let row;
    while(row=stringifier.read()){
        data.push(row);
    }
});
stringifier.on("finish",()=>{
    fs.writeFile("newcsv.csv",data,(err)=>{
        if(err){
        return console.error(err);
        }
    });
});
stringifier.write(['root','x','0','root','/root','/bin/bash']);
stringifier.write(['zxp','x','10224','1024','/home/zxp','bin/bash']);
stringifier.end();

报错如下

node:internal/fs/utils:879
  throw new ERR_INVALID_ARG_TYPE(
  ^

TypeError [ERR_INVALID_ARG_TYPE]: The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received an instance of Array

    at processTicksAndRejections (node:internal/process/task_queues:83:21) {

求解决方案！
