delete your package-lock.json file and npm install again. Any dependencies they do no have installed simply use npm i npm is a node package manager and manages all of your packages to be able to run code. Check out what it is so you have a better idea of what you are doing. Environment setup can be a pain, sorry usually is a pain...
