@Blueprint dateInput不工作

Question

我正在尝试使用blueprint DateInput组件，并且我已经完全遵循了文档，但是我就是不能让它工作。如果您有时间，我将非常感谢您的帮助！

下面是我的代码：

import React from 'react';
import * as moment from 'moment';
import { DateInput } from '@blueprintjs/datetime';

class SupplierPage extends React.Component { // eslint-disable-line react/prefer-stateless-function
  constructor(props) {
    super(props);
    this.state = {
      closeOnSelection: true,
      date: null,
      disabled: false,
      format: FORMATS[0],
      reverseMonthAndYearMenus: false,
      timePrecision: undefined,
    };
  }

  render() {
    const { date, format, ...spreadProps } = this.state;
    return (
      <div>
        <DateInput
          {...spreadProps}
          {...format}
          defaultValue={new Date()}
          className="foofoofoo"
          popoverProps={{ popoverClassName: 'barbarbar', content: 'hi' }}
          inputProps={{ className: 'bazbazbaz' }}
        />
      </div>

);
  }
}

export const FORMATS = [
  {
    formatDate: (date) => (date == null ? '' : date.toLocaleDateString()),
    placeholder: 'JS Date',
    parseDate: (str) => new Date(Date.parse(str)),
  },
  momentFormatter('MM/DD/YYYY'),
  momentFormatter('YYYY-MM-DD'),
  momentFormatter('YYYY-MM-DD HH:mm:ss'),
];

function momentFormatter(format) {
  return {
    formatDate: (date) => moment(date).format(format),
    placeholder: `${format} (moment)`,
    parseDate: (str) => moment(str, format).toDate(),
  };
}

下面是错误：

我是不是漏掉了什么明显的东西？我已经搜索了网络上所有可用的资源，但没有运气：

伙计们，你需要react 16+才能让它工作。
