@types/webpack-merge doesn't work with webpack v5

See original GitHub issue

Not sure if this is the correct place, or if I should create this issue in DefinitelyTyped.

I get the following issue:

node_modules/@types/webpack/index.d.ts:32:3 - error TS2305: Module '"../../tapable/tapable"' has no exported member 'Tapable'.

32   Tapable,
     ~~~~~~~

node_modules/@types/webpack/index.d.ts:1062:23 - error TS2707: Generic type 'SyncWaterfallHook<T, AdditionalOptions>' requires between 1 and 2 type arguments.

1062             resolver: SyncWaterfallHook;

I can reproduce it here: https://github.com/nzjony/copy-webpack-plugin-types-typescript-test/blob/types-webpack-merge-issue/test.ts

Simply git clone the https://github.com/nzjony/copy-webpack-plugin-types-typescript-test/tree/types-webpack-merge-issue branch and run npm install && npm run build to reproduce the error.

Can you open this issue at copy-webpack-plugin repository or DefinitelyTyped? webpack-merge doesn’t depend on webpack types directly so we cannot fix the issue here.

1062 resolver: SyncWaterfallHook; It is similar to this issue: DefinitelyTyped/DefinitelyTyped#49528 (comment)

@nzjony Maybe that’s the problem. webpack-merge comes with types and you shouldn’t use @types/webpack-merge as that’s obsolete.
