No value accessor for form control with unspecified name attribute Angular 2

You should add the ngDefaultControl attribute to your input like this:
<div>
<button type="button" class="btn btn-primary"
[(ngModel)]="disabledV" btnCheckbox
btnCheckboxTrue="1" btnCheckboxFalse="0" ngDefaultControl>
{{disabled === '1' ? 'Enable' : 'Disable'}}
</button>
</div>

Admin over 5 yearsYour error doesn't seem to come from here. If you think it's library related, consider removing it and installing it again.

Admin over 5 yearsIt doesn't tell you to add it, it tells you what properties you can use on your
ng-select
selector. -
Emad joha over 5 yearsi'm know from error from html binding the html file not undefined to property binding like [allowClear] or [items] <ng-select [allowClear]="true" [items]="items" [disabled]="disabled" (data)="refreshValue($event)" (selected)="selected($event)" (removed)="removed($event)" (typed)="typed($event)" placeholder="No city selected"> </ng-select>
