Does not build with typescript 2.4.1

[AlexViderman]

RxJS version:
5.4.1

Code to reproduce:

Expected behavior:
No issues with typescript 2.3.4

Actual behavior:
Upgraded my Angular 4 to typescript 2.4.1 and getting the following error on build:

[at-loader] Checking finished with 2 errors

Error in bail mode: [at-loader] ./node_modules/rxjs/Subject.d.ts:16:22
    TS2415: Class 'Subject<T>' incorrectly extends base class 'Observable<T>'.
  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:
Using it with Webpack 3 (Tried with 2 as well, same issue)

It's dupe of #2539 and we're working on to bump up compiler version, but probably with next major.

@kwonoj thank you

Try going to tsconfig.json file in your project and add in
"compilerOptions":{

"skipLibCheck": true

}
This worked for me.
