javascript - 在 Vercel 上部署 React 应用程序后出现空白屏幕

问题描述

我的 package.json 文件，我还尝试在其中包含以前的解决方案“主页”...

我在这里错误地添加了任何语法错误或引用？我的构建成功，但我只能在部署的站点中看到空白页

我的 App.js 文件，我在其中导入了所有 React 和 Redux 路由器。

import "./App.css";
import Sidebar from "./Components/Sidebar";
import { BrowserRouter, Route, Switch } from "react-router-dom";
import FoodCatalog from "./Components/Pages/FoodCatalog";
import 'bootstrap/dist/css/bootstrap.min.css';
import Promotions from "./Components/Pages/Promotions";
import UserManagement from "./Components/Pages/UserManagement";
import axios from 'axios';
import { Provider } from "react-redux";
import thunk from "redux-thunk";
import { createStore, applyMiddleware, compose } from "redux";
import reducer from './redux/reducers'
import Tickets from "./Components/Pages/Tickets";



function App() {
  return (
    <Provider store={store}>
    <BrowserRouter>
      <div className="App">
        <div>
          <Sidebar />
        </div>

        <div style={{width: '100%',overflow: 'hidden'}}>
          <Switch>
            <Route path="/foodcatalog" component={FoodCatalog } />
            <Route path="/promotions" component={Promotions } />
            <Route path="/usermanagement" component={UserManagement } />
            <Route path="/tickets" component={Tickets } />
          </Switch>
          
        </div>
      </div>
    </BrowserRouter>
    </Provider>
  );
}

export default App;

解决方案

指定“主页”</p>

如果您使用 create-react-app，则不必处理 Webpack 配置。（这很好）相反——无论是否弹出——我们只需要在 package.json 中指定“主页”：

例子

create-react-app 设置 webpack 配置的方式，这会将 publicPath 替换为您的应用程序的正确基本 URL。（如果您想了解有关 publicPath 设置的更多信息，请查看 Webpack 文档）
