npm run start在终端中运行时出现以下错误。

尝试导入错误：“重定向”未从“react-router-dom”导出。

我已经重新安装了node_modules，，react-router-dom。react-router还重新启动了终端和我的计算机，但问题仍然存在。

我的代码：

import React from 'react';
import { Switch, Redirect } from 'react-router-dom';

import { RouteWithLayout } from './components';
import { Minimal as MinimalLayout } from './layouts';

import {
  Login as LoginView,
  Dashboard as DashboardView,
  NotFound as NotFoundView
} from './views';

const Routes = () => {
  return (
    <Switch>
      <Redirect
        exact
        from="/"
        to="/dashboard"
      />
      <RouteWithLayout
        component={routeProps => <LoginView {...routeProps} data={data} />}
        exact
        layout={MinimalLayout}
        path="/login"
      />
      <Redirect to="/not-found" /> …

我试图让调光器仅在点击ETH或Select a token按钮点击时显示。我什至无法让状态部分工作，所以我可以连接按钮。

function Main () {
  const [accountAddress, setAccountAddress] = useState(null);
  const [show, setShow] = useState(false);

return (
    <div ref={contextRef}>
      <Dimmer.Dimmable as={Segment} dimmed={show}>
          <Grid style={styles.grid}>
            <Grid.Row>
              <Grid.Column>
                <Card style={styles.card} centered>
                  <Card.Content>
                    <Card.Header style={styles.padding}>Swap / Pool</Card.Header>
                      <Input style={styles.padding} fluid type='text' placeholder='0.0'>
                        <Label basic>From</Label>
                        <input />
                        <Button>ETH <Icon name='angle down' /></Button>
                      </Input>
                      <Input style={styles.padding} fluid type='text' placeholder='0.0'>
                        <Label basic>To</Label>
                        <input />
                        <Button>Select a Token <Icon name='angle down' /></Button>
                      </Input>
                      <Button style={styles.padding} color='teal' fluid size='large'>
                        Connect Wallet
                      </Button> …
