Just tried this on a clean CRA install, and the console is throwing an error when I try to start the app.

Steps to reproduce
$ npx create-react-app new project
cd in, then...
$ npx install-peerdeps --dev eslint-config-wesbos
then there's an install using yarn prompt, go past that, successfully installed.
$ yarn start
then, WHAM!

Running through those instructions solves the issue, so you might want to remove eslint from the peerdeps for new installs.
