想把数据存成excel文件，百度了说需要安装node-xlsl，但我这边一直安装失败。安装步骤如下：
1.新建一个node-js云函数excel2
2.在excel2右键点“内建终端打开”
3.在终端中运行：npm install node-xlsl，报错

折腾了一下午，重启了客户端，突然就安装上了，也是见了鬼了
没有问题啊，我也是用这个做的导出
excel failed: Error: cloud.callFunction:fail -404011 cloud function execution error. 云函数执行错误
1. 报错如下：云端堆栈信息(error stack)(requestId 2414f342-eba2-11eb-bdab-32a98484f02d, callid 1627036719606-0.12601751593543375):
Runtime.ImportModuleError: Error: Cannot find module 'node-xlsx'
2.node-xlsx的安装路径在云函数excel2\node-modules\node-xlsx
3.云函数excel2\index.js代码如下：
// 云函数入口文件
const cloud = require(”wx-server-sdk“)
cloud.init()
//操作excel用的类库
const xlsx = require(”node-xlsx&“)
// 云函数入口函数
exports.main = async (event, context) => {
try {
。。。
4.改成xlsx= require(”node/mudules/node-xlsx&“),也是同样报错
const xlsx = require('node-xlsx');
// 把数据保存到excel里
let buffer = await xlsx.build([{
name: title + timeUtil.timestamp2Time(this._timestamp, 'Y-M-D'),
data,
options
}]);
