ESLint - चयनकर्ता को एक तत्व के रूप में इस्तेमाल किया जाना चाहिए

मैं ESLint के साथ एंगुलर 12 का उपयोग कर रहा हूं। जब भी मैं ng lint निष्पादित करता हूं, ESLint निम्नलिखित चयनकर्ता पर क्रोधित होता है।

10:13 त्रुटि चयनकर्ता को एक तत्व के रूप में उपयोग किया जाना चाहिए (https://angular.io /guide/styleguide#style-05-03) @angular-eslint/component-selector

उपयोग:

<li app-menu-item *ngFor="let item of model; let i = index" [item]="item" [index]="i" [root]="true"></li>

मैं उस नियम को .eslintrc.json से हटा सकता था, लेकिन मैं इसे ठीक कर दूंगा। मैं इसे कैसे ठीक करूं?
