嗨，我正在创建一个 SPFX 天气 webpart，但出现了此错误：

当我运行 gulp build 时没有出现任何错误。我不确定如何调试我的问题。这是我遇到问题的 proptypes.shape() 代码片段：

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,
    };

我想指出的是，我首先使用 react 创建了 webpart，它运行良好，但是当我创建一个 SPFX 应用程序并将我现有的代码转移到其中时，我遇到了这些错误。

这是我的 package.json
