default export of index.d.ts potential problem?

[sawmurai]

Hi!

Since this line was introduced a new typescript error popped up in our build process:

../../node_modules/vue-component-type-helpers/index.d.ts:1:16 - error TS2693: 'string' only refers to a type, but is being used as a value here.

1 export default string;
                 ~~~~~~


Found 1 error in ../../node_modules/vue-component-type-helpers/index.d.ts:1

error Command failed with exit code 1.

We typecheck via vue-tsc, our typescript config looks like that:
