title: Cannot resolve symbol useParams
body: <p>I'm creating an app with react in using WebStorm. I am attempting to use react-router-dom useParams. I have react-router-dom 5.1.2 as a dependency, but useParams is grayed out in import statement. When I hover over useParams it says "Cannot resolve symbol useParams". I am also trying to import Switch and i'm receiving a similar message "Cannot resolve symbol Switch". What's even more unusual is Link is being imported from react-router-dom. </p>
