use providers to initiate your providers in component.使用providers程序在组件中启动您的提供程序。
@Component({
selector: 'yourselector',
styleUrls: [''],
templateUrl: '',
providers: [Angulartics2GoogleAnalytics]
})
Try this.尝试这个。

Your problem should reside in your constructor:您的问题应该存在于您的构造函数中：
constructor(angulartics2GoogleAnalytics: Angulartics2GoogleAnalytics) {}
you should add eg public in front of your provider:你应该在你的提供者前面添加例如public ：
constructor(public angulartics2GoogleAnalytics: Angulartics2GoogleAnalytics) {}
