Angular2 - 没有TemplateRef的提供者(ng2-bootstrap)

Question

我一直在尝试这个错误的几个解决方案,但没有找到任何成功的方法来克服这个:没有提供TemplateRef!

错误日志:

EXCEPTION:未捕获(在承诺中):错误:./FooterComponent类中的错误FooterComponent - 内联模板:15:20导致:没有TemplateRef的提供者!错误:./FooterComponent类中的错误FooterComponent - 内联模板:15:20导致:没有TemplateRef的提供程序!

未处理的Promise拒绝:./FooterComponent类中的错误FooterComponent - 内联模板:15:20导致:没有TemplateRef的提供者!; 区域:角; 任务:Promise.then; 值:

                </div>
            </div>
        </div>
    </div>
</div>

我试着做以下事情:

1. 研究:但是,只有发现实际包含一些指令喜欢的模板答案/解决方案ngIf,ngSwitch等等.(忘记了*,例如)

2. 添加TemplateRef到providers.这就是我得到的:

类型'{selector:string; templateUrl:string; 提供者:typeof TemplateRef []; }'不能分配给'Component'类型的参数.属性"提供者"的类型是不兼容的.类型'typeof TemplateRef []'不能分配给'Provider []'类型.类型'typeof TemplateRef'不能分配给'Provider'类型.类型'typeof TemplateRef'不能分配给'FactoryProvider'类型.'typeof TemplateRef'类型中缺少属性'provide'.

我将尝试看看如何以某种方式添加TemplateRef到应用程序的模块providers.但我不知道这是否是解决方案.我希望有人在我继续研究的同时提出解决方案.

谢谢!:d

*在这里失踪:

<ul class="dropdown-menu pull-right text-left" dropdownMenu>

应该

<ul class="dropdown-menu pull-right text-left" *dropdownMenu>

来自ng2-bootstrap:

<div class="btn-group" dropdown>
  <button dropdownToggle type="button" class="btn btn-primary dropdown-toggle">
    Button dropdown <span class="caret"></span>
  </button>
  <ul *dropdownMenu class="dropdown-menu" role="menu">
    <li role="menuitem"><a class="dropdown-item" href="#">Action</a></li>
    <li role="menuitem"><a class="dropdown-item" href="#">Another action</a></li>
    <li role="menuitem"><a class="dropdown-item" href="#">Something else here</a></li>
    <li class="divider dropdown-divider"></li>
    <li role="menuitem"><a class="dropdown-item" href="#">Separated link</a>
    </li>
  </ul>
</div>
