When you’re talking to an open source dev, just remember that they are literally giving you their time for free, and they are people who don’t like to be treated poorly.
Edit: Just to be clear, I don’t mean any ill will toward the guy. He’s frustrated and he’s just taking it out in the wrong venue at the wrong people, but that doesn’t mean he’s a bad person.
Edit 2: The reinstalling he’s talking about is NPM. So just running npm install. It’s because he tried removing the node_modules directory, which is a reasonable thing to do, but it means you need to reinstall the modules with that command.
That’s absolutely a ridiculous stance. Yes, you can personally go through everything, but there’s also searching around to find out what other people say about it, actually look through the issues people have raised. Some of it applies to proprietary software as well, find out what other people say about the software. You don’t need to do everything yourself, but you do have to take responsibility for trying to make sure it will work as you hope it will.
Whoosh
