数字的Formik输入值即使在作为数字通过Formik验证之后也会变成字符串

import { Formik, Field, ErrorMessage } from 'formik';
import * as Yup from 'yup';

const validationSchema = Yup.object().shape({
  number: Yup.number().required('Number is required'),
});

const MyForm = () => (
  <Formik
    initialValues={{ number: '' }}
    validationSchema={validationSchema}
    onSubmit={(values) => {
      // 处理表单提交
    }}
  >
    <form>
      <Field type="text" name="number" />
      <ErrorMessage name="number" component="div" />
      <button type="submit">Submit</button>
    </form>
  </Formik>
);
