Cannot find type definition file for 'webpack-dev-server' @5.1.0

[byuji]

After upgrading from 5.0.8 to 5.1.0 I got the following error:

$ tsc --noEmit
node_modules/webpack-merge/dist/index.d.ts:1:23 - error TS2688: Cannot find type definition file for 'webpack-dev-server'.

1 /// <reference types="webpack-dev-server" />
                        ~~~~~~~~~~~~~~~~~~


Found 1 error.

I reverted and it works fine. Running yarn add @types/webpack-dev-server --dev also fixes it.

Node version is v10.19.0, using macOS v10.15.6

Thanks for the heads up. It should work without now. I'm not exactly sure how the build picked up the reference since there's no dependency on the type.

I made sure the development dependencies are up to date and now the result seems to be what's expected.
