What steps will reproduce the bug?

Repo case: https://codedamn.com/playground/--6R64znbeUkhqixLdUX_

If that doesn't work:

Make a file with just this one line:

require('child_process');

Save it as child.js.

bun run child.js

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

Just need to import child_process.

What is the expected behavior?

Child process loads.

What do you see instead?

Result:

error: Cannot find package "child_process" from "/Users/dylang/example/child.js"

Additional information

Note this is not the same error as when a module has not been installed or is an internal module not yet supported. That would look like this:

error: Could not resolve: "child_____process". Maybe you need to "bun install"?

I don't believe bun supports child_process yet. See #159

[dylang]

Thanks @boehs, I missed that in my searching!

Maybe we can provide more friendly error messages for unimplemented node packages, such as

Bun has not yet implemented node's child_process package. You will need to disable code that uses this for now. Follow #595 for progress on this feature.

I landed upon this by running a Node.js script that uses Commander, and the Commander package prints this same error.

Commander is a very popular package for CLI tools.

This seems to be an issue using jsdom also.

import * as jsdom from 'jsdom'

console.log(jsdom)

error: Cannot find package "child_process" from "/Users/thee/git-repo/bun-migrate/scraper/node_modules/jsdom/lib/jsdom/living/xhr/XMLHttpRequest-impl.js"

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

Just need to import child_process.

If you need child_process now, you can use 3rd package like bun-utilities and after implementation you can use native module child_process

I got this issue while using commander.js (Cannot use bun with commander..)

I am working on this.

I am working on this.

How's your progress? 🙏

[tomByrer]

@xhyrom might have to assign someone else to this please. Not having child_process is holding up MANY people from using Bun as they wish.

[sno2]

How's your progress? 🙏

I already talked to Jarred about switching my progress to someone else because I have school now. Although, he has not replied yet. Now, there should be people getting paid to do this stuff, so you'll most likely see child_process soon.

@Jarred-Sumner Any update on child_process?
