I've found a bunch of somewhat related answers but can't seem to fix so far...

Bit new to React (and I'm tirrred) so have no clue - I've created a new React app with create-react-app, then added the Github Pages bits in package.json per here.

On npm run build it's failing to compile. Error below. things I've tried:

• Removing and reinstalling node_modules
• clearing npm cache
• destroying and rebuilding proj from scratch

> react-scripts build

Creating an optimized production build...
