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

I have made the below two changes in package.json file.

1) changed the rxjs version to 5.4.1 in dependencies section.

"dependencies": {
"rxjs": "5.4.1" }

2) changed the typescript version to 2.4.0 in devDependencies section.

"devDependencies": { "typescript": "2.4.0" }

I ran 'npm install' command after making the two changes and it worked.
