Angular version: 8.2.14
ng2-tooltip-directive version: 2.10.3

Do I need to upgrade Angular to use to use the latest ng2-tooltip-directive library? Any suggestion?

I'm having the same issues with version 11.2.11

I have the same issue with ɵɵFactoryDeclaration:

static ɵfac: i0.ɵɵFactoryDeclaration<TooltipComponent, never>;
static ɵcmp: i0.ɵɵComponentDeclaration<TooltipComponent, "tooltip", never, { "data": "data"; "show": "show"; }, {}, never, never>;

Install an earlier version. [2.9.22] fixes this.
