Cannot find module 'package.json'

[ntrrgc]

This plugin chokes on imports like this one:

import Bag from "typescript-collections/dist/lib/Bag";

🚨   Could not load commonjs-proxy:
<project>/node_modules/typescript-collections/dist/lib/util.js
(imported by <project>/node_modules/typescript-collections/dist/lib/Dictionary.js):
Cannot find module 'package.json'

typescript-collections has a package.json, of course.

Thank you for your report.

That's weird, I just tried to bundle this module (typescript-collections), and I can't reproduce the problem. Can you share your configuration (package.json, rollup.config.js)?

[mjeanroy]

If you can't share your configuration, feel free to look at this repository to reproduce the problem: https://github.com/mjeanroy/test-rollup-plugin-license

FWIW, I'm running into this as well, on commonjs-proxy.

https://github.com/dropbox/dropbox-sdk-js/tree/license. I tried pasting my package.json and rollup.config.js into your test, which just generates an empty dependencies.txt for me.

Same error occurred for me, I resolved it by re-ordering my rollup plugins.

@Havunen it would be nice if you could tell what you did... Move The plugin license up or down ? After which other plugin ?

Cheers

OK, I got it. The bug was caused by the leading NULL 0x00 Unicode character in front of the path of internal modules, typically added by Babel. So, hooking rollup-plugin-license before Babel could avoid the issue, but I strongly believe that those cases should be handled properly, because it's a norm wanted by rollup. See rollup/rollup#2121 for some related issues.

I've locally fixed the issue, and I'll try to find the time to do a proper PR.

Cheers!

Thank you very much @GerkinDev for your report. I'm waiting for your PR, but if you don't have enough time, I can fix it myself.
