react-router-dom 中的路由器在控制台中抛出错误，没有任何消息

Question

我目前正在构建一个应用程序，并且运行正在处理来自 Route 组件的这个奇怪的 react-router-dom 错误。

我不确定为什么当我在 webpack 中启用“devtool: 'inline-source-map'”时会收到生产错误消息，但基本上我不确定是什么引发了错误。这是我当前的前端设置

import React from 'react';
import { render } from 'react-dom';
import { BrowserRouter as Router, Route } from 'react-router-dom';
import HomePage from './components/Homepage';

render(
  <Router>
    <div> Hello from react </div>
    <Route path="/" element={<HomePage />} /> 
  </Router>,
  document.getElementById('app-portal')
);

并通过注释掉 <Route path="/" element={<HomePage />} /> 该应用程序可以正常工作，但我当然需要 Route 才能为该应用程序工作...

这是我的 package.json 依赖项。

    "axios": "^0.26.1",
    "express": "^4.17.3",
    "html-webpack-plugin": "^5.5.0",

    "style-loader": "^3.3.1",

有人运行遇到过类似的问题吗？如果有，是如何解决的？

正如评论中所指出的，该应用是生产版本，因此删除了调试信息。不过在错误日志中，这些是链接，因此您实际上可以单击它并查看一些形式的代码，看看问题出在哪里，代码抛出错误。

根据您的代码，我假设错误是您没有将 Route 组件渲染到 Routes 组件中。 Routes 组件是处理路由路径匹配的组件，在 react-router-dom@6.

中是必需的

import React from 'react';
import { render } from 'react-dom';
import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';
import HomePage from './components/Homepage';

render(
  <Router>
    <div>Hello from react</div>
    <Routes>
      <Route path="/" element={<HomePage />} /> 
    </Routes>
  </Router>,
  document.getElementById('app-portal')
);

react-router-dom 中的路由器在控制台中抛出错误，没有任何消息
