npm start 编译失败

Question

这是 npm start 的问题，运行 react-scripts start。请问，谁能帮帮我？

我正在尝试在我的应用程序中使用 Swiper，但我在控制台上收到此错误。

!UPDATED：添加了使用 swiper 的代码。

Failed to compile.
./node_modules/swiper/dist/js/swiper.esm.bundle.js
Module not found: Can't resolve '/home/lemes/Projects/idealnemoloko-react/node_modules/babel-preset-react-app/node_modules/@babel/runtime/helpers/esm/assertThisInitialized' in '/home/lemes/Projects/idealnemoloko-react/node_modules/swiper/dist/js'

Laso 为您提供 package.json

我希望这会有所帮助

package.json

我使用 swiper 的文件： 食谱/index.js

this.swiper = new Swiper('.recipes-swiper-container', {
  direction: 'vertical',
  speed: 1000,
  slidesPerView: 1,
  allowTouchMove: false,
  mousewheel: true,
  pagination: {
    el: '.recipes-swiper-pagination',
    clickable: true,
  },
  on: {
    transitionEnd: this.handleSlideTrans
  }
});

main/index.js

 hasLoaded() {
    if(this.state.isLoading === true) {
      this.setState({isLoading: false})

      this.swiper = new Swiper('.swiper-container', {
        direction: 'vertical',
        preventInteractionOnTransition: true,
        speed: 1000,
        autoplay: {
          delay: 5000,
          disableOnInteraction: false,
        },
        slidesPerView: 1,
        initialSlide: this.props.index,
        allowTouchMove: false,
        mousewheel: {
          eventsTarged: '#main-page'
        },
        pagination: {
          el: '.swiper-pagination',
          type: 'bullets',
          clickable: true
        },
      });

      this.swiperInfo = new Swiper('.swiper-container-info', {
        direction: 'vertical',
        preventInteractionOnTransition: true,
        speed: 1000,
        slidesPerView: 1,
        allowTouchMove: false,
        initialSlide: this.props.index
      });

      this.swiper.on('slideNextTransitionStart', () => {
        this.swiperInfo.slideNext();
      });
      this.swiper.on('slidePrevTransitionStart', () => {
        this.swiperInfo.slidePrev();
      });

      var pag = document.getElementsByClassName('swiper-pagination')[0].clientHeight;
      document.getElementById('info-back').style.top = 'calc(50% - ' + pag/window.innerHeight*100/3.25 + 'vh)';
    }
  }

  swiperStart() {
    this.swiper.autoplay.start();
  }

为什么/index.js

this.swiper = new Swiper('.why-swiper-container', {
      direction: 'vertical',
      speed: 1000,
      slidesPerView: 1,
      allowTouchMove: false,
      mousewheel: true,
      pagination: {
        el: '.why-swiper-pagination',
        clickable: true,
      },
      on: {
        transitionEnd: this.handleSlideTrans
      }
    });

我认为您需要Swiper。

您需要像这样导入Swiper 包：

import Swiper from 'swiper/dist/js/swiper.js'
