.d.ts is not a module

[joaomilho]

When generating types for a package, I get 2 files: like_button.d.ts and index.ts.

like_button.d.ts

/// <reference types="react" />
declare module "like_button/LikeButton" {
    type LikeButtonProps = {
        a: 1;
    };
    export default function LikeButton(props: LikeButtonProps): JSX.Element;
}

index

export * from './like_button';

But typescript complains in the index.

Any suggestion?
