The problem

Hello, I was trying to transfer my lib from using Rollup to Tsup, but it fails silently, both for ESM and CJS, with no any errors in stderr.

Command:

tsup src/index.ts --format cjs,esm --dts

Result:

Reproduction repository: https://github.com/talentlessguy/parsec

note that it builds fine with rollup + rollup-plugin-typescript2

Solution

Catch all errors and output them in the stderr
