./node_modules/@angular/core/fesm5/core.js 中的角度警告？

Question

我在部署时不断收到这些警告：

WARNING in ./node_modules/@angular/core/fesm5/core.js
4996:15-36 Critical dependency: the request of a dependency is an expression
 @ ./node_modules/@angular/core/fesm5/core.js

 @ ./src/main.ts
 @ multi (webpack)-dev-server/client?http://localhost:8080 ./src/main.ts

我试过的：

我的项目结构：

我的 webpack.config.js：

当我将 Angular 应用程序从 6 更新到 7 时，出现相同的警告消息。

我通过在 tsconfig.json 的 compilerOptions 中添加路径来删除该消息，"@angular/": ["../node_modules/@angular/"]

但我不确定这是最好的解决方案。
