【问题描述】：
我已经使用 React 构建了我的博客，它在开发模式下运行良好，但是如果我将它上传到 Netlify，它在生产构建中显示为空白页面并出现错误。
Uncaught TypeError: Cannot convert undefined or null to object
at Function.getPrototypeOf (<anonymous>)
at Object.<anonymous> (utils.js:48)
at f (index.html:1)
at Object.<anonymous> (URL.js:4)
at f (index.html:1)
at Object.<anonymous> (webidl2js-wrapper.js:3)
at f (index.html:1)
at Object.<anonymous> (index.js:3)
at f (index.html:1)
at Object.<anonymous> (api.js:7)
一开始我删除了整个 src 和 public 文件夹，这是因为我使用相同的方法上传我的其他 react 项目并且它按预期工作。
