Question

我正在尝试测试旋转木马但是当我加载页面时它是空白的。

我用npm安装了反应引导程序。

诉讼代码来自https://react-bootstrap.github.io/components.html#media-content。我查看了我的网络控制台，我也没有任何警告或错误。

carousal.js

import React, { Component } from 'react';
import {Carousel} from 'react-bootstrap';
class carousel extends Component {
    render() {
        return (
            <Carousel>
                <Carousel.Item>
                    <img width={900} height={500} alt="900x500" src={require('./images/cs_logo.png')}/>
                    <Carousel.Caption>
                        <h3>First slide label</h3>
                        <p>Nulla vitae elit libero, a pharetra augue mollis interdum.</p>
                    </Carousel.Caption>
                </Carousel.Item>
                <Carousel.Item>
                    <img width={900} height={500} alt="900x500" src={require('./images/cs_logo.png')}/>
                    <Carousel.Caption>
                        <h3>Second slide label</h3>
                        <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
                    </Carousel.Caption>
                </Carousel.Item>
                <Carousel.Item>
                    <img width={900} height={500} alt="900x500" src={require('./images/cs_logo.png')}/>
                    <Carousel.Caption>
                        <h3>Third slide label</h3>
                        <p>Praesent commodo cursus magna, vel scelerisque nisl consectetur.</p>
                    </Carousel.Caption>
                </Carousel.Item>
            </Carousel>
        );
    }
}

export default carousel;

如此处所述，组件需要大写。 Simple React component not rendering

React Bootstrap组件未显示
