从'react-dates'库中添加SingleDatePicker时,我收到了此错误.尝试了一切,但找不到错误.代码只是显示日历并显示用户选择的日期.请帮忙!这是代码:

import React from 'react';
import moment from 'moment';
import { SingleDatePicker } from 'react-dates';
import 'react-dates/lib/css/_datepicker.css';

export default class ExpenseForm extends React.Component {
  state = {
    createdAt: moment(),
    calenderFocused: false
  };
  onDateChange = (createdAt) => {
    this.setState(() => ({ createdAt }));
  };

  onFocusChange = ({ focused }) => {
    this.setState(() => ({ calenderFocused: focused }));
  };

  render() {
    return (
      <div>
        <form>
          <SingleDatePicker
            date={this.state.createdAt}
            onDateChange={this.onDateChange}
            focused={this.state.calendcalenderFocused}
            onFocusChange={this.onFocusChange}
          />
        </form>
      </div>
    );
  }
};
