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 funny thing is that since it’s an actual word the spell checker might not be of any use to see that it might not be the word you’re actually wanting to use. And with the amount of people using “payed” instead of “paid” the dictionaries will probably include “payed” as an alternative way to conjugate “to pay” in the currency sense.
