public/electron.js.我需要不依赖任何软件吗？

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())
}

不确定为什么在生成后显示空白页。尝试了不同的方法，但没有成功

不确定您是否在ReactJS中实现了路由，但我通过使用HashRouter而不是BrowserRouter进行了修复...示例：

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>
  )

以防有人像我一样偶然发现这个问题，我通过改变来解决我的问题

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
  }));

确保你需要路径和url并且也让mainwindow

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();

此问题是由于应用程序的构建文件夹和入口点之间的链接错误所致
请勿以这种方式使用
主窗口.loadURL（是开发人员吗？“http：//localhost：3000”：（x 1m 0n 1x）;
以这种方式使用
主窗口.loadURL（是开发人员吗？“http：//localhost：3000”：x 1m 1n 1x）;
如果您使用React路由器，则必须替换（Router）〉〉（HashRouter）

const { app, BrowserWindow } = require('electron')

       const appURL = app.isPackaged
        ? url.format({
            pathname: path.join(__dirname, "index.html"),
            protocol: "file:",
            slashes: true,
        })
        : "http://localhost:3000";
    mainWindow.loadURL(appURL);

    if (!app.isPackaged) {
        mainWindow.webContents.openDevTools();
    }
