Hook problems when using #fluentui/react - reactjs

Question

I'm trying to use the Link component in #fluentui/react, but I get an error about invalid hook calls. I tried using Link in office-ui-fabric-react, but got same hook error.
Background:
Component A calls the code with the Link component.
Component A is in a different folder than Link component.
Error:
"react-dom.development.js:3198 Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
You might have mismatching versions of React and the renderer (such as React DOM)
You might be breaking the Rules of Hooks
You might have more than one copy of React in the same app"
Link code:
import * as React from "react";
import { Link } from "#fluentui/react";
//import { Link } from "office-ui-fabric-react";
export interface ITestProps {
what: string;
click: () => void;
}
export default class TestComponent extends React.PureComponent<ITestProps, {}> {
constructor(props: ITestProps) {
super(props);
}
render() {
return (
<div>
Test {this.props.what}
<button onClick={this.props.click}>Click</button>
<Link onClick={this.props.click}>Click link</Link> <-- this is what is causing hook problems
</div>
);
}
}
Then I tried using a functional component rather than extending from React.PureComponent, but same hook error:
export default function TestComponent(props: ITestProps) {
return (
<div>
Test2 {props.what}
<button onClick={props.click}>Click</button>
<Link onClick={props.click}>Click link</Link> <-- also produces hook error
</div>
);
}
The only way that I solved this problem is my Link code inside the same folder as the Component that uses the Link code.
I want to be able to put my Link code in a separate folder, not in the same folder as Component A.
I also made sure that the react and react-dom version of both folders are the same, but I still got hook errors.
Please any suggestions?
