Question

从@ babel / polyfill获取有关未找到某些依赖项的错误消息。

为什么没有与@ babel / polyfill一起安装这些依赖关系

These dependencies were not found:

* core-js/fn/array/flat-map in ./node_modules/@babel/polyfill/lib/noConflict.js
* core-js/fn/promise/finally in ./node_modules/@babel/polyfill/lib/noConflict.js

To install them, you can run: npm install --save core-js/fn/array/flat-map core-js/fn/promise/finally core-js/fn/string/pad-end core-js/fn/string/pad-start core-js/fn/string/trim-end core-js/fn/string/trim-start core-js/fn/symbol/async-iterator core-js/library/fn/array/is-array core-js/library/fn/global core-js/library/fn/parse-float core-js/library/fn/parse-int

对我来说，问题是在nodeJs环境中偶然需要lib（core-js）（因为vscode自动导入新功能）。

我正在处理的项目包含2个文件夹：

/lib =>供前端使用的已编译/精简版（必须具有core-js）
/src =>未被编译供后端nodeJ使用（应该不需要core-js）

我希望这会引导您走上正确的道路：）

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