为什么电子通过vue.js'无法找到电子应用程序'？

Question

我对电子和vue.js完全陌生。所以我开始了一个新的宠物项目。一些Electron ipcs可以正常工作，因此我在项目中添加了Vue或更好地尝试添加Vue。现在我遇到以下错误：

尽管“就在一分钟前”工作正常。

那么为什么电子在安装vue后找不到该应用程序？

这是我的文件：

package-json;

  },

}

main.js

const electron = require('electron')
const app = electron.app
const BrowserWindow = electron.BrowserWindow
const ipc = electron.ipcMain
const Vue = require('electron-vue')

let mainWindow

app.on('ready', _ => {
    mainWindow = new BrowserWindow(
        {webPreferences: {
            nodeIntegration: true
          }}
    )

    mainWindow.loadURL(`file://${__dirname}/mainview.html`)

    mainWindow.on('closed', _ => {
        console.log('closed!')
        mainWindow = null

    })

    // instantiate Vue
    var ssv = new Vue({
        el: 'ssv',
        data:{
            appName : 'SodukoSovler with Vue'
        }
    })

    console.log('Here we are!'); 
})

ipc.on('start-search', _ => {
    console.log("new search started")
    mainWindow.webContents.send('search-started')
    console.log('Search started in main.js!')
})

我希望，我已提供了所需的任何信息。 感谢您的帮助！
