Answer 1

发生此错误是因为我正在做...

public this.getDocuments$ = this.streamCreatorService.etc
constructor(private streamCreatorService: StreamCreatorService) {
}

因此我在准备好之前使用了注入的服务。

将其更改为...

public this.getDocuments$;
constructor(private streamCreatorService: StreamCreatorService) {
}
ngOnInit() {
    this.getDocuments$ = this.streamCreatorService.etc
}

修正了它。错误消息会有所帮助。浪费了3个小时。

Comeon Zone.JS和ng2，整理出来！

来自zone.js 0.8.1（最新版本）的

，error.stack将删除大多数与区域相关的堆栈帧，请尝试一下。 https://github.com/angular/zone.js/commit/76fa891b88f85bb975ac69c23e620c915e71bf84
