I'm trying to set up eslint on my Next.js project. I followed the guide here https://nextjs.org/docs/basic-features/eslint

When I run yarn lint, I receive the error error - ESLint must be installed.

In my "devDependencies" in package.json, I have the following:

"eslint": "^8.0.1",
"eslint-config-next": "11.1.2"

I tried running yarn add --dev eslint, but I still receive the same error after running the lint command.

Edit: This is an existing project. Was created with yarn create next-app. Versions for next and react below

"next": "^11.1.2",
"react": "^17.0.2"

Node v14.18.1

ESLint v8 introduced breaking changes that impact compatibility with Next. Downgrading to 7.32.0 seems to work for most people.

The Next team is currently working on adding v8 support.
