我想这是因为你已经有formGroupName包裹你的邮编两次，你的HTML应该是这样的： -

<div class="container"> 
    <h3>Add user:</h3> 
    <form [formGroup]="myForm" novalidate (ngSubmit)="Create(myForm.value, myForm.valid)"> 
     <ul> 
      <div class="form-group"> 
       <label for="name">name:</label> <input type="text" class="form-control" formControlName="name"><br/> 
       <small [hidden]="myForm.controls.name.valid || (myForm.controls.name.pristine && !submitted)" 
         class="text-danger"> 
        name is required. 
       </small> 
      </div> 

      <div class="form-group" formGroupName="adress"> 
       <label for="">adress</label> 
       <input type="text" class="form-control" formControlName="street"> 
       <small [hidden]="myForm.controls.adress.controls.street.valid || (myForm.controls.adress.controls.street.pristine && !submitted)" 
         class="text-danger"> 
        street required 
       </small> 

       <label for="">postcode</label> 
       <input type="text" class="form-control" formControlName="postcode"> 

       <button class="btn btn-default" (click)="CreateVersion()">create</button> 
      </div> 

     </ul> 
    </form> 
</div>
