如何修复vue电子应用上的白屏

Question

运行npm run build:build在安装并启动应用程序后，我会看到一个白屏。

我在代码库中使用Vue路由器，但在服务器上，这个应用程序运行得很好，处于一个好的位置。

我已经尝试确保index.html导入是正确的，斜杠也是正确的

我会提供我的background.js

'use strict'

import { app, protocol, BrowserWindow } from 'electron'
import { createProtocol } from 'vue-cli-plugin-electron-builder/lib'
import installExtension, { VUEJS_DEVTOOLS } from 'electron-devtools-installer'
const isDevelopment = process.env.NODE_ENV !== 'production'
const fs = require('fs');

// Scheme must be registered before the app is ready
protocol.registerSchemesAsPrivileged([
  { scheme: 'app', privileges: { secure: true, standard: true } }
])

async function createWindow() {
  // Create the browser window.
  const win = new BrowserWindow({
    width: 1200,
    height: 800,
    title: "Universal Actuator Pack",
    webPreferences: {
      // Use pluginOptions.nodeIntegration, leave this alone
      // See nklayman.github.io/vue-cli-plugin-electron-builder/guide/security.html#node-integration for more info
      nodeIntegration: process.env.ELECTRON_NODE_INTEGRATION,
      contextIsolation: !process.env.ELECTRON_NODE_INTEGRATION
    }
  })

  if (process.env.WEBPACK_DEV_SERVER_URL) {
    // Load the url of the dev server if in development mode
    await win.loadURL(process.env.WEBPACK_DEV_SERVER_URL)
    if (!process.env.IS_TEST) win.webContents.openDevTools()
  } else {
    createProtocol('app')
    // Load the index.html when not in development
    win.loadURL(
      url.format({
        pathname: path.join(__dirname, `/dist/index.html`),
        protocol: "file:",
        slashes: true
      })
    );
  }
}

// Quit when all windows are closed.
app.on('window-all-closed', () => {
  // On macOS it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('activate', () => {
  // On macOS it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (BrowserWindow.getAllWindows().length === 0) createWindow()
})

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', async () => {
  if (isDevelopment && !process.env.IS_TEST) {
    // Install Vue Devtools
    try {
      await installExtension(VUEJS_DEVTOOLS)
    } catch (e) {
      console.error('Vue Devtools failed to install:', e.toString())
    }
  }
  createWindow()
})

// Exit cleanly on request from parent process in development mode.
if (isDevelopment) {
  if (process.platform === 'win32') {
    process.on('message', (data) => {
      if (data === 'graceful-exit') {
        app.quit()
      }
    })
  } else {
    process.on('SIGTERM', () => {
      app.quit()
    })
  }
}

如果你正在使用vue-router，就像我在你的电子应用程序中一样，你需要添加一个创建的钩子到你的应用程序和路由器puch，如下所示

new Vue({
  router,
  store,
  render: h => h(App),
  created() {
    // Prevent blank screen in Electron builds
    console.log('Electron loaded')
    this.$router.push('/')
  }
}).$mount('#app')

这解决了我的问题
