Rxjs: getting "Types of property 'lift' are incompatible." with typescript 2.4.0

Created on 28 Jun 2017 · 11Comments · Source: ReactiveX/rxjs

RxJS version: 5.1.0

Code to reproduce: linting a code using Subject

Expected behavior: no errors

Actual behavior:

Types of property 'lift' are incompatible.
Type '<R>(operator: Operator<T, R>) => Observable<T>' is not assignable to type '<R>(operator: Operator<T, R>) => Observable<R>'.
Type 'Observable<T>' is not assignable to type 'Observable<R>'.
Type 'T' is not assignable to type 'R'.

Additional information:
The bug popped up after typescript updated to 2.4.0

If kwonoj would list the problem that lists the solution, that would be helpful. Kwonoj's practice of listing umpteen different dupes only confuses the problem.

There is open issue to track this one and it is on discussion. I'm closing all dupues on behalf of opened one - it doesn't have meaning to open issue without searching dupes.

I understand that you only should track the problem on one ticket. How about specifying on which ticket the problem is being tracked instead having the user go through all four tickets to find the issue tracking the problem?

I'd rather suggest people search issue first before filing redundant issue that I have to just close.
