未捕获的引用错误：React 项目中未定义全局

Question

我正在使用 React 库构建一个项目。当我尝试在本地主机上运行我的项目时，我遇到了下一个问题。

2GlobalStyles.js:13 Uncaught ReferenceError: Global is not defined

react-dom.development.js:18687 The above error occurred in the <GlobalStyles> component:

我已经研究过，这可能是全局 this 重命名为 globalThis 的问题：https://github.com/react-simple-code-editor/react-simple-code-editor/issues/86#issuecomment-860205926 我尝试包含 const global = globalThis;到“公共文件夹”中的index.html文件，但这没有帮助。我之前在 React 中没有遇到过这个问题。

您能提供建议吗？ 谢谢你。
