How do I get around this “Subject incorrectly extends Observable” error in TypeScript 2.4 and RxJS 5.x?

Question

When I compile, I get the following compiler error in the RxJS declaration files:

node_modules/rxjs/Subject.d.ts(16,22): error TS2415: Class \'Subject

        

Answer 1

This is a mismatch issue between rxjs and typscript, using "rxjs": "5.4.2" and "typescript": "~2.3.4" works for me
