node_modules/clean-webpack-plugin/dist/clean-webpack-plugin.d.ts:1:33 - error TS7016: Could not find a declaration file for module 'webpack'. '/node_modules/webpack/lib/webpack.js' implicitly has an 'any' type.
  Try `npm install @types/webpack` if it exists or add a new declaration (.d.ts) file containing `declare module 'webpack';`

1 import { Compiler, Stats } from 'webpack';

I'm getting this error even though I'm not using typings on my Webpack configs at all, so it shouldn't be happening. I know I can just install the @types/webpack myself, but since the package is using it for something, it actually should be included as a dependency and installed automatically once I get the package.

From TS docs:

For that reason, we used "dependencies" and not "devDependencies", because otherwise our consumers would have needed to manually install those packages. If we had just written a command line application and not expected our package to be used as a library, we might have used devDependencies.
