可以通过将minZoom prop设置为0.1来解决这个问题，如下所示：

import React, { useState } from 'react';
import ImgCrop from 'antd-img-crop';
import { Upload } from 'antd';

const Demo = () => {
  const [fileList, setFileList] = useState([]);

  const onChange = ({ fileList: newFileList, file }) => {
    setFileList(newFileList);
  };

  const onPreview = async file => {
    let src = file.url;
    if (!src) {
      src = await new Promise(resolve => {
        const reader = new FileReader();
        reader.readAsDataURL(file.originFileObj);
        reader.onload = () => resolve(reader.result);
      });
    }
    const image = new Image();
    image.src = src;
    const imgWindow = window.open(src);
    imgWindow.document.write(image.outerHTML);
  };

  return (
    <>
      
        
          {fileList.length < 5 && '+ Upload'}
        
      
    
  );
};

export default Demo;
