Steps to reproduce:

• git clone https://github.com/eslint/eslint.git
• npm install

[mdjermanovic]

Some dependencies/devDependencies have ESLint as a peer dependency.

Assuming that you're using Node 16, you'll have to use --force or --legacy-peer-deps flag when installing a beta version, because "8.0.0-beta.1" doesn't satisfy requirements such as "eslint": ">=5".

We set npm install --force in our CI (ref #14933).

@mdjermanovic thanks !
