npm WARN ERESOLVE overriding peer dependency

Question

I am trying to update react and react-dom from 17.0.2 to 18.0.2 in a component library project.

I get an error npm WARN ERESOLVE overriding peer dependency

The peerDependency is react@">=16.3".

18.0.2 >= 16.3, so why would this be an error?

$> npm install --save-dev --save-exact react@18.0.2 react-dom@18.0.2
