Without --minify i get this error:

Can you provide a minimal example of the cli.ts file?

[malezjaa]

Sure https://github.com/maripose-js/maripose/blob/main/src/cli.ts

[seofernando25]

@malezjaa might not be the answer you are looking but taking a look at that project I think the command you are looking for is bun run build would it be not?

[malezjaa]

No I was trying to build project using bun build because it's faster than tsup.

No I was trying to build project using bun build because it's faster than tsup.

oh my bad, I had just skimmed over it.

[seofernando25]

I was able to mostly isolate the error.

It seems its happens with the @rsbuild/core pkg which uses enhanced-resolve

import { createRsbuild } from "@rsbuild/core";

const rsbuild = await createRsbuild();

Running bun build ./index.ts --target bun gives me

                       ^

Minimal reproduction example with v1.1.2

Only the minify issue might be windows specific, ~~it seems it has to do with how bun tries to bundle pnpapi which doesn't actually exists but its definitelly a bun bug.~~

I'm not a core developer so I wouldn't know how much I could help :sweat_smile:

[seofernando25]

My solution

@malezjaa I was able to build your project by marking pnpapi and /dist/loader.js as external (resolved at runtime)

$: bun build ./src/cli.ts --minify --target bun --external pnpapi --external "./dist/loader.js" --outdir dist

does it builds for you (with and without minify)? I'm on linux so there is a chance we might have different results

This looks like its fixed now 🎉 (at least from my tests, and my issue linked above also is fixed at least on canary)

[cworld1]

I'm not canary user and use scoop for pm. Looking forward to author's next update, which can include this feat/fix.
