Sorry, I should have mentioned that I tried that too. My original command was:
yarn create next-app beer-shop
It threw the same error though.
I got around it by simply using npx create-next-app beer-shop instead, then yarn install once inside the project to start using yarn.
I’m just curious as to what I might have done to make yarn throw Strapi errors when I’m not even using Strapi. It’s likely my fault, something to do with moving my web project folders into a new directory or something but can’t put my finger on it.
