오류: 참조 또는 변수에 할당할 수 없습니다!앵귤러 4
새로운 HTML 코드를 추가한 후에 각도 4에서 오류가 발생합니다. 이전에는 양식이 정상적으로 작동했습니다.새로운 코드에 주석을 달려고 했지만 여전히 작동하지 않습니다. - 어떻게 해야 할지 - 이 오류를 조사하고 해결하려고 했지만 도움이 되지 않았습니다. 문제의 정확한 위치를 알 수 없습니다.
내 코드:
<form role="form" #adminForm="ngForm" (ngSubmit)="logAdmin(adminForm.form)">
<div class="form-group">
<input class="form-control" [(ngModel)]="adminUsername" #adminUsername="ngModel" placeholder="Username" type="text" name="adminUsername"
required>
<div *ngIf="adminUsername.touched && adminUsername.errors">
<div class="alert alert-danger" *ngIf="adminUsername.errors.required">Username is required</div>
</div>
</div>
<div class="form-group">
<input class="form-control" [(ngModel)]="passwordText" #adminPassword="ngModel" id="adminPassword" name="adminPassword" placeholder="Password"
type="password" required>
</div>
<div class="alert alert-danger" *ngIf="adminPassword.touched && adminPassword.errors">Password is required</div>
<div class="col-md-6" style="text-align: right">
<button type="submit" class="btn-yellow" [disabled]="!adminForm.valid">Log In</button>
</div>
</form>
오류가 발생했습니다.

인터넷에서 검색해보니 같은 오류에 대한 질문과 답변이 있었습니다. 하지만 저는 저에게 맞는 해결책을 찾지 못했습니다.그렇기 때문에 이 오류가 반복될 수 있지만 정답은 다른 많은 사람들과 다른 것 같습니다.
문제는 제가 ngModel 변수 이름을 정확히 똑같이 바꿨다는 것입니다.
[(ngModel)]="adminUsername" #adminUsername="ngModel"
나에게 효과적인 솔루션
[(ngModel)]="adminUsernameText" #adminUsername="ngModel"
