我遵循了文档https://www.npmjs.com/package/react-owl-carousel2，并尝试集成猫头鹰轮播2。它是图像轮播。即使更改了项目选项值，所有图像也都显示为一侧。下面是我的代码。任何人都可以看看为什么它不起作用。

import React from 'react';
import OwlCarousel from 'react-owl-carousel2';  
import 'owl.carousel/dist/assets/owl.carousel.css';  
import 'owl.carousel/dist/assets/owl.theme.default.css';  

export default class CalendarView extends React.Component{
    render(){
        const options = {
            items: 1,nav: true,rewind: true,autoplay: true
        };
        
        return(
            <div>
                <div>This is Calendar View</div>
                <div classname='container-fluid' >            
                
                <OwlCarousel classname="owl-theme" options={options} margin={4}>
                    <div>
                        <img classname="img" src= {'../assets/img/completed_case_1.png'} height="250px"/>
                        <img classname="img" src= {'../assets/img/completed_case_2.png'}  height="250px"/>
                        <img classname="img" src= {'../assets/img/completed_case_3.png'}  height="250px"/>
                        <img classname="img" src= {'../assets/img/gallery_4.png'} height="250px"/>
                        <img classname="img" src= {'../assets/img/gallery_5.png'} height="250px"/>
                    </div>      
                </OwlCarousel>  

             </div>
            </div>
            
        );
    }
}

这是输出正在得到
