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.
People who take stuff for free and compain them are bad people ngl.
Complaining in and of itself isn't bad. Hell, a bug report is a complaint and it's very much useful. As are feature requests. Whining definitely isn't good, but complaints can and often are useful, warranted and lead to a positive outcome
