Fair warning: I know nothing about nodeJS/npm/nvm so this is the blind leading the blind

I was getting the same error and decided to give up, and uninstalled everything nodejs related (I don't know if this is necessary), and then came back to try again and got it working. Or at least it installs, launches, and appears to be working. Here is what I did:

1. install nvm
   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.1/install.sh | bash

2. reload .bashrc to get nvm recognized by bash
   source ~/.bashrc

3. use nvm to install current version of node, and use it. And have nvm install npm
   nvm install node
nvm use node
nvm install-latest-npm

4. Use npm to install shader-school
   npm install -g shader school

5. move to some directory to run shader-school, becase it will make a bunch of directories

6. run shader-school
   shader-school

Hope this helps

I'm getting the following using the latest version of node.

[2/4] 🚚  Fetching packages...
error pngjs@0.4.0: The engine "node" is incompatible with this module. Expected version "0.8.x". Got "14.3.0"

@robksawyer Same issue just popped to me, were you able to solve it?

The following worked for me when installing it locally on ArchLinux from a clone of the repository. (I am writing this comment to report that this can still work.

Here's what I did:

# clone the repo
$ git clone https://github.com/stackgl/shader-school
$ cd shader-school
# install dependencies
$ npm install
# start the server
$ npm start

And then I could visit http://localhost:12492 for the course.

For reference, I have the following versions of node & npm:

$ node --version
v16.10.0
$ npm --version
7.24.2
