So you're a Preact user, but want to use some React libraries with it. You wanted to set up aliases or something, but can't do it for some reason. The solution is simple, though:
yarn add preact preact-compat
yarn add preact-compat/react preact-compat/react-dom
Or if you're not a fan of yarn:
npm i -S preact preact-compat
npm i -S preact-compat/react preact-compat/react-dom
