请教老师文件写入为什么没有生效
通过nodejs直接执行fileHelper.js是生效的，在App.js中调用就不生效了，但的确走了promise的resolve

electron中的nodejs版本是12.8.1
electron版本 7.1.1
windows 10

fileHelper.js

const fs = window.require('fs').promises
const path = window.require('path')

const fileHelper = {
  readFile: (path) => {
    return fs.readFile(path, {encoding: 'utf8'})
  },
  writeFile: (path, content) => {
    console.log(path, content, '---文件操作入参')
    return fs.writeFile(path, content, {encoding: 'utf8'})
  },
  renameFile: (path, newPath) => {
    return fs.rename(path, newPath)
  },
  deleteFile: (path) => {
    return fs.unlink(path)
  }
}

App.js

import fileHelper from './utils/fileHelper'
const {remote} = window.require('electron')
const {join} = window.require('path')
const savedLocation = remote.app.getPath('documents')
 fileHelper.writeFile(join(savedLocation, `${title}.md`), files[id].body)
 .then(res => {
   // setFiles({...files, [id]: newFile})
   console.log('完成', res)
 }).catch(err => {
   console.log('异常', err)
 })
