我目前正在構建一個應用程式，并且在 Route 組件中遇到了這個奇怪的 react-router-dom 錯誤。
我不確定為什么在 webpack 中啟用“devtool：'inline-source-map'”時會收到生產錯誤訊息，但基本上我不確定是什么引發了錯誤。這是我當前的前端設定
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')
);
并通過注釋掉<Route path="/" element={<HomePage />} /> 應用程式的作業原理，但我當然需要 Route 才能為這個應用程式作業......
這是我的 package.json 依賴項。

有沒有人遇到過類似的問題？如果是這樣，它是如何解決的？
uj5u.com熱心網友回復：
正如評論中所指出的，該應用程式是一個生產版本，因此除錯資訊被洗掉。但是在錯誤日志中，這些是鏈接，因此您實際上可以單擊它并查看某種形式的代碼并查看問題出在哪里，代碼拋出錯誤。
根據您的代碼，盡管我假設錯誤是您沒有將組件呈現Route為Routes組件。該Routes組件用于處理路由路徑匹配，并且在react-router-dom@6.
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')
);
