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

In tsconfig.json, put it in "compilerOptions" and set it to true.

{
    "compilerOptions": true,
    "compilerOptions": {
        "noStrictGenericChecks": true
    }
}
