Describe the Bug

When I run next lint I receive an error error - ESLint must be installed: yarn add --dev eslint.
In package.json I have eslint installed "eslint": "^8.0.1".
Also my IDE works with local eslint correctly.

package.json

"scripts": { "dev": "next dev", "build": "next build", "start": "next start", "lint": "next lint", "format": "prettier --write src/**/*.{js,jsx,ts,tsx,css,md,json} --config ./.prettierrc" },
...
"devDependencies": { "@commitlint/cli": "^13.2.1", "@commitlint/config-conventional": "^13.2.0", "autoprefixer": "^10.3.7", "eslint": "^8.0.1", "eslint-config-next": "^11.1.2", "eslint-config-prettier": "^8.3.0", "eslint-plugin-prettier": "^4.0.0", "eslint-plugin-simple-import-sort": "^7.0.0", "husky": "^7.0.2", "postcss": "^8.3.9", "prettier": "^2.4.1" }

eslint.json

{ "extends": ["next/core-web-vitals", "plugin:prettier/recommended"], "plugins": ["simple-import-sort"], "rules": { "prettier/prettier": ["error", {}, { "usePrettierrc": true }], "simple-import-sort/imports": "error", "simple-import-sort/exports": "error" } }

Without simple-import-sort plugin bug is also reproducing

Expected Behavior

ESLint should work

To Reproduce

Install next 11.1.2
Add script "lint": "next lint" to your package.json
Run "yarn lint"

This workaround works for me #29977

Hello.

Eslint 8 is not supported yet.
A pull request is opened here: #29865 to address this issue.

In the meantime, you can downgrade to Eslint 7.

@tooshikii and @thibautsabot are correct, ESLint 8 is not yet supported so please downgrade to v7 for the meantime

• yarn remove eslint && yarn add --dev eslint@"<8.0.0"
• npm uninstall eslint && npm install --save-dev eslint@"<8.0.0"

Closing this since it's a duplicate!
