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.
The nightmare just crawls out to our reality when paid software is less developed on and more buggy than free Open Source software.
That’s because the people making it are doing it for a job rather than for the love of it. (Except me. Surely I don’t do that.)
