在电子生成器对电子应用程序做出react后，在 Windows 中出现空白屏幕。

这是 package.json。在电子生成器对电子应用程序做出react后，在 Windows 中出现空白屏幕。

公共/电子.js。我需要安装任何依赖吗？

const { app, BrowserWindow,Menu } = require('electron')
require('../src/messgaeController/main');
const path = require("path");
const isDev = require("electron-is-dev");

let addItem ;
let win;
function createWindow () {
   win = new BrowserWindow({
    width: 800,
    height: 600,
    icon:"build/icon.ico",
    webPreferences: {
      nodeIntegration: true,
      // webSecurity: false
    }
  })

  win.loadURL(isDev? "http://localhost:3000": `file://${__dirname}/../build/index.html`);
    win.on("closed", () => (mainWindow = null));

  const mainMenu = Menu.buildFromTemplate(menuTemplate);
  Menu.setApplicationMenu(mainMenu);
  // win.webContents.openDevTools()

  win.on("close",()=>app.quit())
}

不知道为什么它在构建后显示空白页。尝试了不同的方法，没有用

如果有人像我一样偶然发现了这个，我通过改变解决了我的问题

win.loadURL(isDev? "http://localhost:3000": `file://${__dirname}/../build/index.html`);

到

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

确保您需要路径和网址，并让主窗口

const path = require("path");
const url = require('url');

let mainWindow;

我也改变了

win.on("closed", () => (mainWindow = null));

到

mainWindow.on("closed", () => (mainWindow = null));

我还将路由器历史记录更改为哈希

import { createHashHistory } from 'history';
export default createHashHistory();

不确定你是否在 ReactJS 中实现了路由，但我通过使用 HashRouter 而不是 BrowserRouter 来修复......例如：

return (
    <HashRouter>
        <div>
        <Header/>
            <Switch>
             <Route path="/" component={Home} exact/>
             <Route path="/news" component={News} exact/>
             <Route path="/store" component={Store} exact/>
             <Route path="/login" component={Login} exact/>
             <ProtectedRoute path="/profile" component={Profile} exact/>
           </Switch>
        </div> 
      </HashRouter>
  )
