</div>并运行react-router-dom时，浏览器中断了
这是我的npm start：
package.json在我的"dependencies": {
"react": "16.8.3",
"react-dom": "16.8.3",
"react-router-dom": "4.3.1",
"react-scripts": "2.1.5"
},
"eslintConfig": {
"extends": "react-app"
},
"browserslist": [
">0.2%",
"not dead",
"not ie <= 11",
"not op_mini all"
]
}
中：
index.js在我的 import React from 'react';
import App from './components/App';
import 'bootstrap/dist/css/bootstrap.css';
import './global.css';
const container = document.getElementById('app');
ReactDOM.render(<App/>, container);
App.js:我做错什么了吗？
