TypeError: source.on is not a function. (In 'source.on("error", emit)', 'source.on' is undefined)

What version of Bun is running?

0.5.9

What platform is your computer?

Darwin 20.6.0 x86_64 i386

What steps can reproduce the bug?

Install a zip-a-folder package:

bun i zip-a-folder

Use it in a script to zip a folder:

import { zip } from 'zip-a-folder'
[...]
await zip(SOURCE_FOLDER, OUTPUT_FILE_PATH)

Same issue with archiver package.

What is the expected behavior?

Everything works (like it does with regular node.js)

What do you see instead?

This error:

we should investigate forcing readable-stream to use bun's internal version of this package

Newest error using Bun v1.0.7. is:

❯ cat zip.js
import { zip } from 'zip-a-folder'
await zip("./demo", "./demo.zip");

❯ mkdir demo
❯ bun zip.js 
SyntaxError: Indirectly exported binding name 'unescape' is not found.

I just ran into this same error with the package form-data. I'm trying to use a ReadableStream with a multipart form (which Bun's FormData doesn't support)

bun 1.0.29
