react-slick

Question

我正在尝试创建一个简单的滑块，但当我 map 数据而不是简单地将 html 添加到滑块时，我收到以下错误：

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

import React from 'react';
import Slider from 'react-slick';
import 'slick-carousel/slick/slick.css';
import 'slick-carousel/slick/slick-theme.css';

const WishAddImage = () => {
    const imgArray = [
        {
            src: 'https://www.reiss.com/media/product/653/024/20-1.jpg?format=jpeg&auto=webp&quality=85&width=250&height=287&fit=bounds'
        },
        {
            src: 'https://www.reiss.com/media/product/993/016/76-1.jpg?format=jpeg&auto=webp&quality=85&width=250&height=287&fit=bounds'
        }
    ];

    const sliderSettings = {
        dots: true,
        infinite: true,
        speed: 500,
        slidesToShow: 1,
        slidesToScroll: 1
    };
    const wishImage = <Slider {...sliderSettings}>{imgArray.map(img => `<div><img src='${img.src}' /></div>`)}</Slider>;

    // const wishImage = ( /* <-- this works as it should when html used */
    //     <Slider {...sliderSettings}>
    //         <div>
    //             <h1>1</h1>
    //         </div>
    //         <div>
    //             <h1>2</h1>
    //         </div>
    //     </Slider>
    // );
    return <div>{wishImage}</div>;
};

export default WishAddImage;

我看过这些类似的问题，但不适用于我：

Uncaught Error: Element type is invalid: expected a string (for built-in components)
Element type is invalid: expected a string (for built-in components) or a class/function

有什么明显的我遗漏的吗？

我正在使用 React & React-dom v 16.6.3

删除引号中的字符：

 const wishImage = <Slider {...sliderSettings}>{imgArray.map(img => <div><img src={img.src} /></div>)}</Slider>;

react-slick - 元素类型无效：需要一个字符串
