Typescript: Generate build error when enums are used in d.ts files

enum in .d.ts files don't work (amd modules) and we get runtime errors, instead if we define as const enum they work. Is there a compiler option we can use to generate a build error when enum is defined instead of const enum in d.ts files.

// foo.d.ts
enum Foo {
   Option1,
  Optino2
}

does not work and gives runtime error about missing module foo

// foo.d.ts
const enum Foo {
   Option1 = 0,
   Option2 = 1
}

works.

I guess you just miss the export key word:

// foo.d.ts
export enum Foo {
   Option1,
   Optino2
}

You can use the TSLint rule called prefer-const-enum.
