When dependencies are installed with pnpm, ts-loader behaves differently than tsc

See original GitHub issue

Expected Behaviour

ts-loader should not report TS2305

Actual Behaviour

ts-loader report TS2305 error

Steps to Reproduce the Problem

npm i -g pnpm
pnpm install
run npm run tsc and observe that the compilation success
run npm start and observe error

This happens to both Linux and Windows 10 host.

It looks like the type information is not visible to TypeScript when the dependency are symlinked and are compiled via ts-loader. I am willing to look into it but not sure where to start.

Thanks for the insight @zkochan and @pgonzal. The reasoning I have so far is that since tsc works while ts-loader doesn’t. It should be the case that they setup the TypeScript compiler differently, the problem shouldn’t be with the compiler itself, otherwise tsc would fail too.

I compared the compiler setup code in ts-loader and tsc but wasn’t be able to get very far there.
