我是角度新手，我遇到了这样的问题：
当我在元素中放入 ngIf 时，
<input type="text" *ngIf="true" id="name" name="name" class="form-control" required [(ngModel)]="name" #name="ngModel" />
aaaaaa {{name.dirty}}
我有
ERROR TypeError: Cannot read property 'dirty' of undefined
at Object.eval [as updateRenderer] (PrepareInvestmentComponent.html:1)
at Object.debugUpdateRenderer [as updateRenderer] (core.es5.js:13105)

但是，当我删除 ngIf 时，它工作正常。我可以知道原因以及解决此问题的任何迹象吗？
