TypeScript errors with noImplicitAny: true

[GuskiS]

Hello. I'm having these errors when using noImplicitAny: true in tsconfig.json. Basicly it needs return type to defined, just not sure which one and how to do it. Is timeago.d.ts file created automatically?

ERROR in [at-loader] ./node_modules/timeago.js/timeago.d.ts:4:5 
    TS7013: Construct signature, which lacks return-type annotation, implicitly has an 'any' return type.
