npm install --save-dev electron
npm install --save-dev electron-builder

const { ipcRenderer } = require('electron')

 pluginOptions: {
        electronBuilder: {
            nodeIntegration: true,
            contextIsolation: false,
        }
    }

const { ipcRenderer } = window.require('electron')

 function importStudy() {
            if (isElectron()) {
                window.ipcRenderer = window.require('electron').ipcRenderer
                ipcRenderer.send('upload', "import study")
                ipcRenderer.on('get-file-path', (event: any, arg: any) => {
                    console.log(arg)
                    })
                })
            }

 <button @click="importStudy">import</button>

ipcMain.on('upload',(event,message)=>{
   console.log(message)
   dialog.showOpenDialog({
    title:'选择要上传的文件',//对话框的标题
    buttonLabel: '确认', //确定按钮的自定义标签
    properties: [ 'openDirectory', 'multiSelections'], //打开文件的属性，打开文件还是文件夹，隐藏文件,多选文件
   }).then(res=>{
    if(!res.canceled){
      console.log(res.filePaths)
      event.reply('get-file-path',res.filePaths)//拿到路径后返回
    }
