Typescript: error TS1183: An implementation cannot be declared in ambient contexts.

Using angular 6 Project I am getting below error:

error TS1183: An implementation cannot be declared in ambient contexts.

Below Error I was facing could you someone help me 👍

ERROR in node_modules/rxjs/internal/Observable.d.ts(14,35): error TS1183: An implementation cannot be declared in ambient contexts.

Could you provide the code example that's failing for you? The latest rxjs has a comment on line 14 of internal/Observable.d.ts.

I have the same problem, my Typescript version is 2.7.2 and i'm using Angular 6, does anyone have any solution ?

[andy-ms]

@Samhot could you provide an example project that reproduces the error?

[Samhot]

It's complicate to provide an example it's not a specific code which doesn't works, I just use Observables in many components... It worked well till this afternoon, since the build is impossible

Don't you think this is as odd as suspecting? I did nothing so that it happened.
Actually, you must execute npm install rxjs in order to fix it, if you do rm -rf node_modules && npm install doesn't work...

I have same issue in d.ts file.

error: Initializers are not allowed in ambient contexts.

declare namespace SportDataErrorCode1 {
  var lDEFAULT_PREFETCH_SIZE: number = 100;
}

In my case it happened when I was trying to add implementation to file that was defined as definition file(some-file.d.ts)
