Attempted import error: 'SomeObject' is not exported from file

问题

I've upgraded to Webpack 4 from 3. Since then, I get a lot of warnings regarding imports that were not exported from certain files.

./packages/utils/logging/index.ts
Attempted import error: ‘Options' is not exported from './loggers/log'.
 @ ./packages/utils/index.ts
 @ ./src/App.tsx
 @ multi whatwg-fetch @babel/polyfill ./src/App.tsx

I use ts-loader along with ForkTsCheckerWebpackPlugin. I've examined the exports from the warnings and they look good. The code does work, however I still get those warnings.

tsconfig.json for reference:
