【问题描述】：
当我在 CLI 中运行“yarn run electron-dev”时，在浏览器中打开http://localhost:3000 显示主页，但电子应用显示空白。
与其他人在生产中遇到问题但在开发中工作的类似问题不同，我遇到了相反的问题。
查看开发工具，浏览器控制台中没有错误，即使我执行 console.log()，控制台中也没有出现任何错误。
electron.js
const electron = require('electron');
const app = electron.app;
const BrowserWindow = electron.BrowserWindow;
const edge = require('electron-edge-js');
const path = require('path');
const isDev = require('electron-is-dev');
require('electron-reload')
let mainWindow;
function createWindow() {
mainWindow = new BrowserWindow({
width: 900,
height: 680,
webPreferences: {
nodeIntegration: true,
},
});
console.log('isDev', isDev);
mainWindow.loadURL(isDev ? 'http://localhost:3000' : `file://${path.join(__dirname, '../build/index.html')}`);
if (isDev) {
// Open the DevTools.
//BrowserWindow.addDevToolsExtension('<location to your react chrome extension>');
mainWindow.webContents.openDevTools();
}
mainWindow.on('closed', () => mainWindow = null);
}
app.on('ready', createWindow);
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') {
app.quit();
}
});
app.on('activate', () => {
if (mainWindow === null) {
createWindow();
console.log('entering func123');
func123();
}
});

It will be replaced with the URL of the `public` folder during the build.
Only files inside the `public` folder can be referenced from the HTML.
Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
work correctly both with client-side routing and a non-root public URL.
Learn how to configure a non-root public URL by running `npm run build`.

【问题讨论】：
-
介意分享您的
index.html文件。在基本 href 之前可能缺少.？ -
当我从 electron.js 中删除电子重载时，它对我有用。 electron-reload 未列在您的 package.json 中。我也遇到了电子边缘 js 的问题。如果我删除这两个依赖项，我可以在 localhost:3000 上加载一个空白 index.html 文件。
-
@PrameshBajracharya 我为这个应用程序使用了 create-react-app 并且没有更改这些文件，所以我认为这不是问题，但我现在已经将它包含在问题中.
-
@narmageddon 我尝试删除两个依赖项 electron-reload 和 electron-edge-js 但我仍然得到空白的电子应用程序
