Cannot use enum from project A from project B even if the function used in B is imported from A

[kenotron]

Error message says:

error TS2345: Argument of type 'Foo' is not assignable to parameter of type 'Foo'.

Given the exact same exported type, Typescript isn't able to deal with enums from multiple source locations. Here's an example with a Core project and a Bar project:

Core/
  foo.ts
  convertFooToString.ts
  dist/
    foo.js
    foo.d.ts
    convertFooToString.ts
    convertFooToString.d.ts

Bar/
  SomeComponent.tsx
  dist/
    SomeComponent.js
    SomeComponent.d.ts

SomeComponent.tsx:

// some other imports
import {convertFooToString}
export default class SomeComponent extends React.Component<any, any> {
  render() {
    // Note, this.props.foo IS a Foo type
    return (<div>{convertFooToString(this.props.foo)}</div>);
  }
}

foo.ts:

enum Foo {
  Yay = 0,
  Nay = 1
};

export default Foo;

convertFooToString:

export function convertFooToString(foo: Foo): string {
    switch (foo) {
        case Foo.Yay:
            return "YAYAYAYAYA";
        default:
            return "NANANANANA";
    }
}

it is not clear what is going on from your description, i do not know where the error is reported, and where hte import is coming from etc.. but this looks like a duplicate of #4800..

This issue was long ago marked as a duplicate. Shouldn't it be closed (especially since the issue it is supposedly a duplicate of, #4800, is actually closed)?
