Fails to `npm i` with Node 16

First off, I'm not familiar with JavaScript so maybe this obvious but it took me a long time to figure this out. Thought I'd open an issue in case someone else sees this. Might be good to add a note to the README.

I had node installed from Homebrew. This currently installs Node 16. One of the dependencies of this project, node-sass, isn't compatible with Node 16.

After awhile, I figured out how to workaround this:

1. Uninstall Homebrew's Node: brew uninstall node
2. Install NVM. I did brew install nvm and then followed the instructions to add it to my shell.
3. Install Node 15: nvm install v15 && nvm use v15
4. After restarting your shell, you can run node -v to confirm you have Node 15 and then run npm i like normal.

Thank you, I'll take a look at Node 16 later today to see if there's any problems. I currently use Node 14
