ESLint peer dependencies

[ghost]

node v4.2.1

running npm install:

npm ERR! peerinvalid The package [email protected] does not satisfy its siblings' peerDependencies requirements!
npm ERR! peerinvalid Peer [email protected] wants eslint@>=2.0.0
npm ERR! peerinvalid Peer [email protected] wants eslint@>=3.0.0

If I update package.json to eslint ^3 it seems to build and install but I don't want to do that without knowing it's the right thing to do.
