SPFx反应无法读取属性＆＃39;形状＆＃39;未定义的

Question

您好我正在创建一个SPFX天气webpart，我收到此错误：

运行gulp build时没有错误。我不知道如何调试我的问题。这是proptypes.shape（）的片段，我得到了我的问题：

import * as React from 'react';
import PropTypes from 'prop-types';
    export const Day: React.SFC<any> = props => {
      const date = props.day.dt;
      const icon = getIcon(props.day.weather[0].id);
      const animate = true;
      const iconSize = 64;
      const iconColor = 'black';
      return (
        <div className={appClasses.dayContainer} onClick={props.onClick} role="link">
            <h2 className={appClasses.date}>{(new Date(date * 1000)).toDateString()} - {(new Date(date * 1000)).toLocaleTimeString()}</h2>
           <ReactAnimatedWeather
                icon={icon}
                color={iconColor}
                size={iconSize}
                animate={animate}
            />
        </div>
      );
    };

    Day.defaultProps = {
      onClick: () => {},
    };

    Day.propTypes = {
      day: PropTypes.shape({
        dt: PropTypes.number.isRequired,
        weather: PropTypes.array.isRequired,
      }).isRequired,
      onClick: PropTypes.func,
    };

我想注意，我首先使用react创建了webpart，它运行正常，但是当我创建了一个SPFX应用程序，并将我现有的代码转移到它中。我遇到过这些错误。

这是我的package.json

你很可能遇到同样的问题。如果您要发布我的github链接供我克隆，我可以为您确认。

TL; DR

您的工厂之间可能有循环引用。您需要将顶级工厂所需的任何代码移动到所述工厂的底部。
