【已解决】Error: Invariant failed: You should not use ＜withRouter(RouterView) /＞ outside a ＜Router＞

Error: Invariant failed: You should not use <withRouter(RouterView) /> outside a <Router>

问题代码：

import React, {Component} from 'react';
import {BrowserRouter as Router, Route, Switch, withRouter} from 'react-router-dom';
import * as A from '../a';
import * as B from '../b';

class RouterView extends Component{
    render() {
        return (
            <Router>
                <Switch>
                    <Route path="/" component={A}/>
                    <Route path="/b" component={B}/>
                </Switch>
            </Router>
        );
    }
}

export default withRouter(RouterView)

解决：将BrowserRouter摘出来即可

over。。。
