I just started working with vscode and npm/git. Someone on my team added a package and I did a pull to get his latest changes which put that package in my package.json file. When I ran the project I got errors for a module not being found. Obviously I need to install that package locally. Do I simply use npm install w/no arguments to get it? Or do I install it manually myself with npm install and version info? I ask because I don't know if npm install w/no args will create a new package.json or cause any issues.

What is the correct way to get a new package installed that someone added in the repo?

npm install can be run as many times as you like, and is what you should be doing here :)

npm install's purpose is to get your node_modules folder up-to-date with whatever is written in package.json

So, if your colleague has changed package.json (by installing something new and pushing the change to git), you can just run the command again to get up-to-date.

Provided you haven't directly fiddled with any files in node_modules (this folder should be left alone), it is always safe to run npm install as many times as you like, even if nothing has changed.
