error on ng serve

[ntodorov]

after cloning and running npm install, when i use ng serve i receive this error:
ERROR in node_modules/@angular/flex-layout/core/typings/observable-media/observable-media.d.ts(1,22): error TS2305: Module '"/Users/nik/Documents/GitHub/angular-file-upload/client/node_modules/rxjs/Rx"' has no exported member 'Subscribable'.

Any idea why?
