當我導入一個.md文件時，它給了我一個錯誤，說它無法讀取這個特定.md file syntax的，我知道需要某種加載器來解析導入，但是當我在網上查看時，有一個加載器叫做'markdown-loader'它只用于markednpm 包。我正在使用react-markdown包來讀取 md 文件/* eslint-disable react/prefer-stateless-function */import React, { Component } from 'react';import ReactMarkdown from 'react-markdown';import AppMarkdown from './posts/sample.md';// import PropTypes from 'prop-types';class CardDetails extends Component {  constructor() {    super();    this.state = { markdown: '' };  }  componentDidMount() {    // Get the contents from the Markdown file and put them in the React state, so we can reference it in render() below.     fetch(AppMarkdown)      .then(res => res.text())      .then(text => this.setState({ markdown: text }));  }  render() {    const { markdown } = this.state;    return <ReactMarkdown source={markdown} />;  }}CardDetails.propTypes = {};export default CardDetails;這是我的降價內容sample.md# React & Markdown App- Benefits of using React... but...- Write layout in Markdown!我找不到包，我到處找，你知道裝載機嗎？謝謝
