Some packages run just fine when using bun directly, but when trying to use bun build it gives this error TypeError: The superclass is not a constructor.
I created a small example repo:
First install the package, for example @solana/web3.js
bun install @solana/web3.js
create file index.js that uses the package:
import * as web3 from '@solana/web3.js';
console.log(web3);
Running this file directly with bun index.js works fine, but when trying to build first and then run it (or when using --compile flag to put it into one executable), it fails:
bun build ./index.js --outdir ./build --target=bun && bun build/index.js

Seen this behaviour in multiple packages now..
