npm install throws a bunch of errors in react project

I'm currently learning how to work with React and everytime I try to work on a course file and run npm install I get back a million errors and warning. On literally every file I try this on. I've made sure I'm inside the right directory and that there is a json file.

I've already tried to reinstall node, update npm to latest version (i'm on 6.14.4) and run npm cache clean but none of those worked. The only thing that worked once was to run a command that was something along the lines of npm install missing dependencies but that's not it, i can't remember it or find it anywhere online now.

You are having a problem with the C compiler of node. Often, this module (node-gyp) is a dependency of one of your dependencies. The problem usually occurs, if not all settings are correctly set. Follow the official installation guide of node-gyp:
Windows: https://github.com/nodejs/node-gyp#on-windows
Mac OS: https://github.com/nodejs/node-gyp#on-macos

You need to install node-gyp
npm install -g node-gyp

any advise on this is greatly appreciated

This is something related to the latest version of NodeJS which is explained here. I would advise you below two options to get rid of this. Choose the best that suits you.
Please setup python in your machine
Downgrade your Nodejs to version 10.X and try it. I am using 10.18.0 and it works perfectly fine. You can download it from here.
Cheers!

Strange npm error when running npm install brain.js

There is not a word about this problem in the documentation for brain.js. Everything is simple there - run npm install brain.js and that's it.
UPDATE 16.08.2019
This instruction marked option 2 helped me
https://github.com/nodejs/node-gyp#on-windows

Make sure the Path and Env variables are set for the Python installed. Also, I found something similar here.. hope it helps!!

Use the command without dot:
npm install brainjs

Blockstack App Fails on npm install ERR! configure error

Does anyone know what I must do to fix this error?

These types of node-gyp errors can be caused when Python 3 is installed on the system and it is expecting Python2.7. The node-gyp contributors claim Python3 support is not perfect at the moment and recommend Python2.7 if you encounter any problems.
It may not be necessary though to change Python versions in your case just yet, since it looks like you are on a Windows machine and it's failing on the node-gyp rebuild step. It's probably worth trying the following command first (make sure you are either in CMD or Powershell in Administrator mode:
npm install -g windows-build-tools
The windows-build-tools package is required for node-gyp to work properly on Windows, as stated here. After this, try running npm install again.
Still fails?
If the problem persist or another error related to node-gyp occurs, you might have to install Python2.7 and set npm to use Python2.7
npm config set python /path/to/executable/python2.7
You can read more about possible node-gyp issues and how to resolve them on the node-gyp github page.

You don't have the appropriate zeromq library headers installed. The name of the package that provides these headers varies depending on your platform/distro. See the zmq readme for complete installation instructions.
