@csandman I think you can try to use this solutions emotion-js/emotion#2343 (comment). I can't do anything because react-select packages is installed in your package

[csandman]

Can you share a list of your dependencies (deps, peer deps, dev deps) so I can look into it?

[csandman]

Also, is this actually causing any problems, or are you just getting the warning?

[csandman]

So I implemented a way to avoid this warning in #115. The main idea is just that your project's @emotion/react version needs to be equal or higher than the version required by React Select (in this case ^11.8.1) which will allow NPM to de-dupe the package, preventing this warning/error.

To enforce this, I set a peer dependency requirement of @emotion/react to be the same as what's required by React Select.
