Cannot add lint-staged: only eslint, stylelint, prettier or custom rules are supported. Continuation of discussion.

I attempted to continue the discussion on #147 but the owner gently just shot down the issue and blocked all comments. What a way to treat your community. Feel free to do the same here but I just wanted to add:

I was able to identify the problem. The error message suggests that only some libraries are supported, but the error in my case was that eslint wasn't installed as devDependencies but instead globally. This is stated is the docs, but the error message could be made more helpful with an addition such as "Are you sure that you installed all dependencies locally"?

Same issue happens on the CRA with pretty simple package.json, I am confused!

I also had this issue setting it up on a monorepo, which has multiple different languages and will have all custom scripts. I think it should warn and then install a minimal setup instead of just failing.

To be 100% clear for future readers, eslint and prettier specifically have to be in devDependencies. Regular dependencies does not work, having them installed as sub-dependencies, peer dependencies, or globally does not work.

The task tries to determine what tools you're using not just based on your npm scripts as implied by the documentation. You can find the code here.

It is definitely confusing that the task has pretty specific requirements for what it's looking for, especially if you're coming from the lint-staged readme (like i'm sure many people are) that doesn't indicate anything besides "make sure you have your other tools set up". The error message is very unclear and at the very least updating that to indicate to the user what configuration it's looking for would be helpful

before running npx mrm@2 lint-staged
make sure you have eslint and prettier in you devDependencies of package.json

{
  "eslint": "^some.version.number",
    "prettier": "^some.version.number"
}

Could dprint be supported directly?
