ngx-bootstrap: Class 'MiniStore' incorrectly extends base class 'Observable

I just update to version 1.8.0 from 1.7.1 and when I compile my app I got a compilation error:

ERROR in /mnt/c/Users/f.dehopre/devs/Portal/node_modules/ngx-bootstrap/mini-ngrx/store.class.d.ts (8,22): Class 'MiniStore<T>' incorrectly extends base class 'Observable<T>'.

Thank you for reply. Even after changing the version I am getting the same error but this time it has introduced other errors related with ngrx/store and some other plugin. Please find the log below regarding ngx-bootstrap

skipLibCheck: true, in tsconfig should help in the meantime

tried to implement different solutions, incl. “skipLibCheck”: true, --noStrictGenericChecks, Module Augmentation, but no results still only editing ngx-bootstrap/mini-ngrx/store.class.d.ts caused successful compilation, but there must be a better solution I guess

import { SelectSignature } from '@ngrx/core';

select: SelectSignature<T>;
lift<R>(operator: Operator<T, R>): Observable<R>;

same error for me “typescript”: “2.3.4”

I’m already on the latest version of rxjs (5.4.2). I tried the latest version of ngx-bootstrap (1.8.1) and I still have the same issue when compiling. Any idea of how I can fix this issue?
