BrowserRouter v4 - 'BrowserRouter' is not defined react/jsx-no-undef
提问by Thomas Hennes
I want to use BrowserRouter in my react app. I have nested my top most component in the BrowserRouter tags as shown:
我想在我的 React 应用程序中使用 BrowserRouter。我在 BrowserRouter 标签中嵌套了最顶层的组件，如下所示：
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router, Route, Link } from 'react-router-dom';
import App from './App';
import registerServiceWorker from './registerServiceWorker';
ReactDOM.render((
<BrowserRouter>
<App/>
</BrowserRouter>
), document.getElementById('root'));
registerServiceWorker();
And I am getting the following error:
我收到以下错误：
./src/index.js
Line 9: 'BrowserRouter' is not defined react/jsx-no-undef
I have installed react-router-dom and the dependancy is in my package.json file. So why am I getting this?
我已经安装了 react-router-dom 并且依赖在我的 package.json 文件中。那为什么我会得到这个？

You imported it as Router, so you should call it as <Router>as well.
您将其导入为Router，因此您也应该调用它<Router>。
