@babel/polyfill:在./node_modules/@babel/polyfill/lib/noConflict.js中找不到这些依赖项:core-js/fn/array/polyfill

Question

从@babel/polyfill获取有关一些没有找到的依赖项的错误消息。

为什么这些依赖项没有与@babel/polyfill一起安装？

对我来说，问题在于nodeJs环境中意外地需要库(core-js) (因为vscode自动导入新特性)。

我正在处理的项目包含两个文件夹：

• /lib =>编译/早期版本供前端使用(需要core-js )
• /src =>未编译以供后端nodeJs使用(如果而不是需要core-js )

我希望这将引导你走上正确的道路:)
