A combination of the 2 answers given here worked for me.
//errorInfoHandler.d.ts
declare module "lib/errorInfoHandler" {
var noTypeInfoYet: any; // any var name here really
export = noTypeInfoYet;
}
I’m still new to TypeScript but it looks as if this is just a way to tell TypeScript to leave off by exporting a dummy variable with no type information on it.
EDIT
It has been noted in the comments for this answer that you can achieve the same result by simply declaring:
//errorInfoHandler.d.ts
declare module "*";
See the github comment here.
