在redux-form中，显示字段级验证中的所有验证错误

<Field name="username" component="input" type="text" validate={[required, minLength(6)]} />

const validate = (values, allValues) => {
  const errors = {};
  if (!values.username) {
    errors.username = '用户名不能为空';
  }
  if (values.username && values.username.length < 6) {
    errors.username = '用户名长度不能少于6个字符';
  }
  // 其他字段的验证规则
  return errors;
};

import { reduxForm } from 'redux-form';

const MyForm = (props) => {
  // 表单组件的实现
};

export default reduxForm({
  form: 'myForm',
  validate,
})(MyForm);

const MyForm = (props) => {
  const { handleSubmit, meta: { error } } = props;
  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label>用户名</label>
        <Field name="username" component="input" type="text" />
        {error && <span>{error.username}</span>}
      </div>
      {/* 其他表单字段 */}
      <button type="submit">提交</button>
    </form>
  );
};
