Can't install sass if react-stonecutter is installed

[Tridib Roy Arjo]

I have a Next app with react-stonecutter installed. But when I try to install sass, react-motion gets deleted. Or, if I install react-motion, sass gets deleted.
I got:

    "react-motion": "^0.5.2",
    "react-scripts": "^5.0.1",
    "react-stonecutter": "^0.3.10"
