无法读取未定义的属性"ngMetadataName"

Question

我正在使用Angular 6和Angular Material.更新到最新版本后,控制台在开发中抛出此错误.在生产上它正在发挥作用

Cannot read property 'ngMetadataName' of undefined

它发生在我试图通过服务打开材料对话框时(没有服务他们工作正常).我认为它与注射剂有关,但我不确定.

版本:cli:6.1.5,核心:6.1.4,材料:6.4.6

这是日志堆栈:

CustomDialogComponent_Host.ngfactory.js? [sm]:1 ERROR TypeError: Cannot read property 'ngMetadataName' of undefined
at injectArgs (core.js:1418)
at core.js:1491

at resolveDep (core.js:9419)
at createClass (core.js:9309)
at createDirectiveInstance (core.js:9186)

任何帮助将不胜感激.

服务中的对话框,其中抛出错误:

 @Injectable({
  providedIn: 'root'
})
export class customService {
  constructor(private store: Store<RootState>, private dialog: MatDialog) {}

const dialogRef = this.dialog.open(customDialogComponent, {
  width: '300px',
  data: {
    loading: false,
    customId,
  }
});

相同的消息但与Material无关,我也有这个错误.我意识到,有一个关于循环依赖的警告.删除依赖项后,此错误消失.

可能是编译过程中的其他警告消息将有助于解决此问题.

使用CLI版本8.0.4升级Angular时遇到此错误。我必须降级到@angular-devkit/build-angular 0.800.3Angular CLI到version 8.0.3。

npm i --save-dev @angular-devkit/build-angular@0.800.3 @angular/cli@8.0.3
