[英]After upgrade Angular to 11 from 10. I get Argument of type 'Subject<void>' is not assignable to parameter of type 'ObservableInput<any>'
I have this line of code in almost every component file where I have subscribe to an observable returning from singleton service file.我在订阅了从 singleton 服务文件返回的 observable 的几乎每个组件文件中都有这行代码。
destroy$: Subject<void> = new Subject<void>()
this._sessionService.toggleMeetingBar.pipe(takeUntil(this.destroy$)).subscribe(result => {
this.barType = "meetingBar";
this._sideNav.toggle();
})
ngOnDestroy(): void {
this.destroy$.next();
this.destroy$.complete();
}
schedule-session.service.ts调度-session.service.ts
public toggleMeetingBar = new Subject<any>();
this._session.upsertSession(sessionData).subscribe(result => {
this.toggleMeetingBar.next(false);
});
Now after upgrading to Angular 11. I get below error flooded in my terminal.现在升级到 Angular 11 后。我的终端中出现以下错误。 There are many other issue regarding Firestore. Firestore 还有很多其他问题。 But I am more concern with this one.但我更关心这个。 I did this to clear the memory when the component is destroyed.我这样做是为了在组件被销毁时清除 memory。
Error: src/app/shared/components/auto-complete/auto-complete.component.ts:77:34 - error TS2345: Argument of type 'Subject<void>' is not assignable to parameter of type 'ObservableInput<any>'.
Type 'Subject<void>' is not assignable to type 'Observable<any>'.
77 .pipe(take(1), takeUntil(this._onDestroy))
How can I fixed this error?我该如何解决这个错误?

I want to confess my sins.我要承认我的罪。
I had used ncu -u
to update my package.json
.我曾使用ncu -u
更新我的package.json
。 So this command when run in your application it will update version of each packages to latest available version.因此,当在您的应用程序中运行此命令时,它会将每个包的版本更新为最新的可用版本。
As suggested by @kvetis and @Chellappan I downgrade rxjs
version from 7 to 6.5.5 (stable) and it worked fine.正如@kvetis 和@Chellappan 所建议的,我将rxjs
版本从 7 降级到 6.5.5(稳定),并且运行良好。 Also I had to downgrade typescript to 4.1.5我还不得不将 typescript 降级到 4.1.5
Everything worked fine after this.在此之后一切正常。
Thanks to everybody who commented.感谢所有评论的人。
EDITED:编辑:
Below RXJS version 7 RXJS以下版本7
destroy$ : Subject<void> = new Subject<void>()
ngOnDestroy(): void {
this.destroy$.next();
this.destroy$.complete();
}
RXJS version 7.1.0 RXJS 版本 7.1.0
destroy$ : Subject<boolean> = new Subject<boolean>()
ngOnDestroy(): void {
this.destroy$.next(true);
this.destroy$.complete();
}
To avoid error.为了避免错误。
try to use a boolean, so onDestroy you cast this.destroy$.next(true).尝试使用 boolean,所以 onDestroy 你施放 this.destroy$.next(true)。 i'm following this guide我正在关注本指南
