角度材质日期选择器为空

I am currently building a web application with Angular and I am using Angular Material for some UI components. Currently, I have an issue that I can't resolve. When I use the datepicker like described on https://material.angularjs.org/latest/demo/datepicker https://material.angularjs.org/latest/demo/datepicker, the window opens but it stays empty.

这是日期选择器的代码片段。

<md-datepicker ng-model="vm.registrationData.birthDate"
                                   md-placeholder="{{'start_register_birth_date' | translate}}"
                                   required></md-datepicker>
                    <div class="error-message"
                         ng-messages="registerForm.birthDate.$error"
                         ng-if="registerForm.birthDate.$touched && registerForm.birthDate.$invalid">
                        <div class="arrow-right"></div>
                        <p ng-message="required">{{'start_register_error_birthDate_required' | translate}}</p>
                    </div>

我的进口可能有问题吗？

使用旧版本的 Angular，例如 1.5.9。 Angular 1.6 禁用控制器的预绑定。

See 问题#10168 https://github.com/angular/material/issues/10168更多细节。你可以加

angular.module('myApp', [])
  .config(function($compileProvider) {
    $compileProvider.preAssignBindingsEnabled(true);
  });

如果你坚持使用 Angular 1.6。
