Commander Package does not work with Bun.

[eli-rich]

What version of Bun is running?

0.2.1 (canary)

What platform is your computer?

Darwin 21.6.0 Darwin Kernel Version 21.6.0: Sat Jun 18 17:07:25 PDT 2022; root:xnu-8020.140.41~1/RELEASE_X86_64 x86_64 i386

What steps can reproduce the bug?

1. Create a new directory.
2. Run bun init
3. Run bun add commander
4. Open index.ts
5. Set contents to the example from the commander github This example has been change to the ESM import syntax. I get the same result with both.

import { program } from 'commander';

program.option('--first').option('-s, --separator <char>');

program.parse();

const options = program.opts();
const limit = options.first ? 1 : undefined;
console.log(program.args[0].split(options.separator, limit));

6. Run bun index.ts

How often does it reproduce? Is there a required condition?

Every time. There seems to be no required condition.

What is the expected behavior?

The program executes without error.

What do you see instead?

error: Cannot find package "child_process" from "/Users/elirichardson/bun/node_modules/commander/lib/command.js"

This should be resolved once we support child_process, #595

It looks like commander should work as of Bun v0.3.0 🎉

If you're still having issue, please feel free to open another issue.
