StaticInjectorError(AppModule)[MatDialogTitle - > MatDialogRef]

Question

我很熟悉这个错误,但我在更新到Angular Material 6.4.7之后才开始看到这个.

我的所有模块都引用了我自己的MaterialModule,它导出了MatDialogModule.我没有MatDialogRef的任何提供程序设置 - 以前不需要.

和[MatDialogTitle - > MatDialogRef]的交易是什么？那是什么意思？

在dev和prod版本中,一切似乎都运行良好.我无法弄清楚造成这种情况的原因.

有没有办法追溯到某事？

谢谢

更新:所以对于我的问题,我能够使用此Bug问题的提供程序解决它[ https://github.com/angular/material2/issues/8419].我在我的app.module提供者列表中添加了以下两行:

{ provide: MatDialogRef, useValue: {} },
{ provide: MAT_DIALOG_DATA, useValue: [] },

该bug指的是测试问题,但对我来说,我有一个MatDialog工作,但另一个会抛出错误.

希望这有帮助,adym
