推荐答案

从 React 15.5.0 开始，PropTypes 已作为单独的依赖项从 React 核心包中删除.要解决此问题，请将 prop-types 添加到您的代码中:

As of React 15.5.0, PropTypes have been removed from the core React package as a separate dependency. To fix this, add prop-types into your code:

如果您通过脚本标签加载:

If you're loading via script tags:

<script src="https://unpkg.com/prop-types/prop-types.min.js"></script>

或者通过 NPM:

npm install --save prop-types
