推荐答案
如果您不想使用数据包管理器，您可以将 React 与 CDN 结合.
If you don't want to use packet managers you can include React with CDNs.
用于开发:
<script src="https://unpkg.com/react@15/dist/react.js"></script>
<script src="https://unpkg.com/react-dom@15/dist/react-dom.js"></script>
用于生产(缩小):
<script src="https://unpkg.com/react@15/dist/react.min.js"></script>
<script src="https://unpkg.com/react-dom@15/dist/react-dom.min.js"></script>
