Reproduction for microsoft/TypeScript#52950
First build the producer:
npm install
npx tsc -p packages/producer-with-package-exportsTest the consumer without baseUrl:
npx tsc -p packages/consumer-without-baseurl
# all imports are resolved correctly, works as expected ✅Test the consumer with baseUrl:
npx tsc -p packages/consumer-with-baseurl
# fails to resolve the import using package exports 💥Get the resolution trace:
npx tsc -p packages/consumer-with-baseurl --traceResolution✅ Good (producer-with-package-exports):
