[antoinerousseau]

Description

I get the warning when running gatsby develop

Steps to reproduce

I'm using the default starter. I run:

gatsby develop

Expected result

No warning

Actual result

Warning: React version not specified in eslint-plugin-react settings.
See https://github.com/yannickcr/eslint-plugin-react#configuration

Note that it's nothing critical, it works anyway.

Thank you for opening this @antoinerousseau

We use eslint-config-react-app under the hood and this was fixed in it in https://github.com/facebook/create-react-app/pull/6132

We'll update once they publish a new version 🙂

After I added the gatsby-browser.js file, I also encountered the same warning.

This is resolved now since eslint-config-react-app was published 4 days ago. Updating gatsby should get rid of the warning.
