Which version is comparable with Angular 7?

[Phalla Doll]

I am using Angular 7 in my project and I found Ng-lightning is looking really professional and standard components to use. So I decide to install it into my Angular 7 project and some angular/cdk that they need. But things aren't right for me, I have an error a lot my console. And I assumed that it might be the version is not comparable with the Ng-lightning version.

These are what I have installed in my project:

• npm install ng-lightning (lastest version)
• npm install @angular/cdk 7.3.7
• npm install @angular/material 7.3.7
• npm install @salesforce-ux/design-system 2.7.5

NOTE: My Angular project version is 7.3.9, Node Js version is 10.16.2
If there something I have missed or because of the version of it? Can anyone help?
