Answer 1

设法解决了它，尽管它是如何修复的仍然是个谜。

我首先使用了git checkout，然后返回到以前的提交，查看错误是否仍然存在。谢天谢地，错误已经过去了。然后，我返回到最近的提交，错误似乎已经解决。

很抱歉，这个答案再有用不过了。但是，如果有任何建议给遇到这种情况的人，请重新访问您认为错误没有持续存在的早期提交，并查看错误是否仍然出现在控制台中。

如果我找到任何进一步的信息，我会发布更多关于这方面的信息。

Answer 2

你试过这个吗

npm install @babel/compat-data

Answer 3

有同样的错误，只是添加了包：

yarn add babel-plugin-macros
