All declarations of 'observable' must have identical modifiers.

Hi,

When i tried to reference ng2-signalr in my angular 6 app.

I get this error when doing ng serve.

ERROR in ../../node_modules/rxjs/internal/symbol/observable.d.ts(4,18): error TS2687: All declarations of 'observable' must have identical modifiers.

I am sure it is the reference to ng2-signalr that causes this.

the version of rxjs i have is
+-- rxjs@6.3.3
+-- rxjs-compat@6.3.3

Thanks,

Bobby
