React 应用程序在部署后显示空白页面[重复]

我之前在 GitHub 和 netlify 上创建并部署了单页 React 应用程序，它们都运行良好。问题在于使用react-router的多页面应用程序。为了测试这一点，我尝试了几次不同的应用程序，一旦我实现了反应路由器并链接到不同的页面，它们在部署后就会变成空白。这是一个测试应用程序：

index.js

import React from "react";
import ReactDOM from "react-dom/client";
import { BrowserRouter } from "react-router-dom";
import "./index.css";
import App from "./App";

const root = ReactDOM.createRoot(document.getElementById("root"));
 root.render(
  <React.StrictMode>
    <BrowserRouter>
     <App />
    </BrowserRouter>
  </React.StrictMode>
  );

App.js

import React from "react";
import { Routes, Route } from "react-router-dom";
import Index from "./pages/Index";
import About from "./pages/About";
import Products from "./pages/Products";
import Navbar from "./components/Navbar";

const App = () => {
return (
<>
  <Navbar />
  <Routes>
    <Route exact path="/" element={<Index />} />
    <Route path="/about" element={<About />} />
    <Route path="/products" element={<Products />} />
  </Routes>
</>
 );
}; 

export default App;

Navbar.js 组件

import React from "react";
import {Link} from "react-router-dom";

const Navbar = () => {
 return (
   <>
   <nav className="navbar">
    <ul>
      <li>
        <Link to="/">home</a>
      </li>
      <li>
        <Link to="/about">about</a>
      </li>
      <li>
        <Link to="/products">products</a>
      </li>
    </ul>
  </nav>
</>
);
};

export default Navbar;

包.json

{
 "name": "test-app",
 "version": "0.1.0",
 "homepage": "https://EricSsSnake/github.io/test-app",
 "private": true,
  "dependencies": {

  "eslintConfig": {

    ]
   },
  "browserslist": {
   "production": [
   ">0.2%",
   "not dead",
   "not op_mini all"
   ],
  "development": [
   "last 1 chrome version",
   "last 1 firefox version",
   "last 1 safari version"
   ] 
  },
 "devDependencies": {
  "gh-pages": "^4.0.0"
 }
}

再加上 3 个要导航的页面。

当我在 GitHub 上部署它时，我得到的只是一个包含这些错误的空白页面。截屏 https://i.stack.imgur.com/gZTzq.png

对于部署，我遵循本教程：反应-gh-页面 https://github.com/gitname/react-gh-pages

我真的很感谢你们的帮助。这个问题阻止了我取得任何进展。我花了三周时间制作我的作品集，但现在它就放在那里了。

update： 将 BrowserRouter 替换为 HashRouter 修复了最初的问题，并且控制台中不再出现任何错误。但是，我现在得到的是一个空白页面，就好像索引页面设置的路由不存在一样。 我认为我现在遇到的问题与此线程类似：将reactjs应用程序部署到github页面后出现空白页面 https://stackoverflow.com/questions/68701401/getting-a-blank-page-after-after-deploying-reactjs-app-to-github-pages

改变 ：

"homepage": "https://EricSsSnake/github.io/test-app",

to :

"homepage": "https://EricSsSnake.github.io/test-app",

and use 哈希路由器代替浏览器路由器。 在你的情况下改变你的index.js像这样 ：

import React from "react";
import ReactDOM from "react-dom/client";
import { HashRouter } from "react-router-dom";
import "./index.css";
import App from "./App";

const root = ReactDOM.createRoot(document.getElementById("root"));
 root.render(
  <React.StrictMode>
    <HashRouter>
     <App />
    </HashRouter>
  </React.StrictMode>
  );

Note :github 页面不支持 React RouterbrowserHistory因为它正在使用HTML5历史API这就是为什么你可以切换到使用哈希值的路由（HashRouter在反应路由器中）检查官方文档创建反应应用程序 https://create-react-app.dev/docs/deployment/#serving-apps-with-client-side-routing
