Vue CLI插件Electron Builder在构建时显示完整的空白屏幕

标签: javascript node.js vue.js electron electron-builder

当我使用this plugin构建电子应用程序时,安装该软件包时得到的只是一个空白的白色屏幕。我已将窗口配置为以内置版本打开开发工具,但是当我查看检查菜单时,页面上唯一的内容是<html><head><body>标签,并且没有错误;控制台完全是空的:

blank screen

元素: elements

控制台: console

我在网上几乎到处都看过,但是那里的解决方案都没有。

我曾尝试将路由器模式从历史记录更改为哈希,并且还运行vue invoke electron-builder,但它们无济于事。

据我所知,这是失败的:

win.loadURL('app://index.html')

因为路径不正确。但是我不知道是这种情况还是其他原因,因为没有错误报告。

这是我的background.js文件:

'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'

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let win

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

function createWindow() {
  // Create the browser window.
  win = new BrowserWindow({
    width: 1500,
    height: 845,
    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: true,
      enableRemoteModule: true
    }
  })


  win.removeMenu()
  win.webContents.openDevTools();
  if (process.env.WEBPACK_DEV_SERVER_URL) {
    // Load the url of the dev server if in development mode
    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('app://index.html')
  }
  win.once('ready-to-show', () => {
    win.show();
  })

  win.on('closed', () => {
    win = null
  })
}

// 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 (win === null) {
    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()
    })
  }
}

如何解决此问题?

因此,经过更多的Google搜索之后,我偶然发现了建议这样做的this site

替换默认的win.loadURL()(看起来像这样:

win.loadURL(formatUrl({
      pathname: path.join(__dirname, 'index.html');,
      protocol: 'file',
      slashes: true
    }))

或者可能有所不同;没关系),与此:

win.loadURL(path.join(__dirname, 'index.html'));

基本上,区别在于这只是删除了formatUrl,这似乎使事情搞砸了。

我替换了我的,这是:

win.loadURL("app://./index.html");

与此有关,现在可以正常工作。

还要确保您也不要删除createProtocol('app')(在win.loadUrl()上方几行),因为您可能会破坏应用程序:)。

我发现解决方案是将路由器模式从“历史记录”更改为“哈希”。因此,在路由器配置中设置:

模式:process.env.IS_ELECTRON? 'hash':'history',
