如何停止 zone.js 吞下你的错误 invoke@node_modules/zone.js

Question

我正在运行进行单元测试，但因 zone.js gumpf 而失败。

我怎样才能得到真正的错误？

错误是...

Answer 1

发生这个错误是因为我在做...

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

因此我在注入的服务准备就绪之前使用它。

正在将其更改为...

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

已修复。错误消息会有所帮助。浪费了3个小时。

加油 Zone.JS 和 ng2，整理一下！

从zone.js 0.8.1（最新版本）开始，error.stack将删除大部分与区域相关的堆栈帧，请尝试。 https://github.com/angular/zone.js/commit/76fa891b88f85bb975ac69c23e620c915e71bf84
