javascript - React : material-ui-pickers date-io Jalaali Utils returns error : TypeError: utils. getDayText 不是函数

Question

这不是 https://github.com/mui-org/material-ui-pickers/issues/1440 的重复因为我对原来的用法没有任何问题。
根据这里的链接https://material-ui-pickers.dev/localization/calendar-systems我使用了 @date-io/jalaali 中的 JalaliUtils。这是我的代码，您可以看到我使用了两个不同的实用程序，其中使用 JalaaliUtils 时出现两个错误:

TypeError: utils.getDayText is not a function

TypeError: utils.getYearText is not a function

相反，如果我使用 @date-io/moment 中的 MomentUtils ，它就可以正常工作，但这不是我想要的。 包本身有什么错误吗？

import React, { useState } from "react";
import moment from "moment";
import jMoment from "moment-jalaali";
import JalaliUtils from "@date-io/jalaali";
import MomentUtils from '@date-io/moment';
import {
  DatePicker,
  MuiPickersUtilsProvider,
} from "@material-ui/pickers";

jMoment.loadPersian({ dialect: "persian-modern", usePersianDigits: true });

function PersianExample() {
  const [selectedDate, handleDateChange] = useState(moment());

  return (
    <React.Fragment>
      <MuiPickersUtilsProvider utils={JalaliUtils} locale="fa">
        <DatePicker
          clearable
          okLabel="ok"
          cancelLabel="cancel"
          clearLabel="clear"
          labelFunc={date => (date ? date.format("jYYYY/jMM/jDD") : "")}
          value={selectedDate}
          onChange={handleDateChange}
        />
      </MuiPickersUtilsProvider>
      <MuiPickersUtilsProvider utils={MomentUtils}>
        <DatePicker value={selectedDate} onChange={handleDateChange} />
      </MuiPickersUtilsProvider>
    </React.Fragment>
  );
}

export default PersianExample;
