我刚刚在我的角度项目中更新了很多包 .

旧的package.json：

}

新的package.json：

{
  "name": "data-jitsu",
  "version": "0.0.0",

    "ts-node": "~5.0.1",
    "tslint": "~5.9.1",
    "typescript": "~2.7.2"
  }
}

当我使用新的package.json更新然后 ng serve 运行 npm install 时，我收到许多编译错误：

src / app / all-matches / all-matches.component.ts（35,39）中的错误：错误TS2339：属性'takeUntil'在类型'Observable'上不存在 . src / app / app.component.ts（28,39）：错误TS2339：属性'takeUntil'在类型'Observable'上不存在 . src / app / authorization.service.ts（19,41）：错误TS2339：属性'of'在类型'typeof Observable'上不存在 . src / app / authorization.service.ts（29,37）：错误TS2339：属性'of'在类型'typeof Observable'上不存在 . src / app / authorization.service.ts（42,39）：错误TS2339：属性'of'在类型'typeof Observable'上不存在 . src / app / authorization.service.ts（66,39）：错误TS2339：属性'of'在类型'typeof Observable'上不存在 . src / app / authorization.service.ts（74,37）：错误TS2339：属性'of'在类型'typeof Observable'上不存在 . src / app / authorization.service.ts（82,39）：错误TS2339：属性'of'在类型'typeof Observable'上不存在 . src / app / database.service.ts（7,31）：错误TS2305：模块'“/ Users / mf / Desktop / dataJitsu / node_modules / angularfire2 / database / index”'没有导出成员'FirebaseListObservable' . src / app / database.service.ts（7,55）：错误TS2305：模块'“/ Users / mf / Desktop / dataJitsu / node_modules / angularfire2 / database / index”'没有导出的成员'FirebaseObjectObservable' . src / app / match-display / match-display.component.ts（27,49）：error TS2339：类型'AngularFireObject <{}>'上的属性'takeUntil'不存在 . src / app / new-match / new-match.component.ts（10,30）：错误TS2305：模块'“/ Users / mf / Desktop / dataJitsu / node_modules / angularfire2 / database / index”'没有导出的成员' FirebaseListObservable” . src / app / new-match / new-match.component.ts（10,54）：错误TS2305：模块'“/ Users / mf / Desktop / dataJitsu / node_modules / angularfire2 / database / index”'没有导出的成员' FirebaseObjectObservable” . src / app / new-match / new-match.component.ts（130,37）：错误TS2339：属性'switchMap'在'Observable'类型上不存在 . src / app / protection.guard.ts（14,34）：错误TS2339：属性'map'在类型'Observable'上不存在 . src / app / test-db / test-db.component.ts（7,30）：错误TS2305：模块'“/ Users / mf / Desktop / dataJitsu / node_modules / angularfire2 / database / index”'没有导出的成员' FirebaseListObservable” . src / app / test-db / test-db.component.ts（7,54）：错误TS2305：模块'“/ Users / mf / Desktop / dataJitsu / node_modules / angularfire2 / database / index”'没有导出的成员' FirebaseObjectObservable” . src / app / user-status-report / user-status-report.component.ts（28,39）：error TS2339：属性'takeUntil'在类型'Observable'上不存在 . src / app / user-status-report / user-status-report.component.ts（33,45）：error TS2339：类型'AngularFireObject <{}>'上的属性'subscribe'不存在 . src / app / user-status-report / user-status-report.component.ts（35,56）：error TS2339：属性'takeUntil'在类型'AngularFireObject <{}>'上不存在 . src / app / user-status-report / user-status-report.component.ts（43,26）：error TS2339：类型'AngularFireObject <{}>'上的属性'takeUntil'不存在 .

大多数这些错误似乎与rxjs有关，我认为是正确的，因为我在更新中使用rxjs v.6，而我的理解是v.5和v.6之间的许多事情都被打破了 .

我玩了安装rxjs-compat npm install rxjs@6 rxjs-compat@6 --save ，我可以确认这个包除了是一个重要的补充之外，还没有解决我看到的任何错误 .

我还根据建议here和here运行ts-lint来自动更新一些更新：

npm i -g rxjs-tslint
rxjs-5-to-6-migrate -p [path/to/tsconfig.json]

我收到以下消息：

没有为JavaScript文件指定有效规则

我猜这意味着我在使用rxjs时没有使用正确的ts约定？

当谈到rxjs时，我仍然非常无能，所以我不清楚究竟还有什么需要重构 .

但我认为我的问题实际上发生在重构蠕虫之前：

我看了第一个错误（

错误TS2339：属性'takeUntil'在类型'Observable'上不存在

一） . 该错误来自我的身份验证服务中的方法 . 在这个服务顶部的import语句（以及大多数其他.ts文件）中，我的IDE是突出显示了很多"cannot find module foo"错误（例如，导入语句的"cannot find module, 'rxjs'"， import { Observable } from 'rxjs'; ） .

同一文件中的类似错误：

import { Injectable, EventEmitter } from '@angular/core'; （"Cannot find module, " @ angular / core“）

import * as firebase from 'firebase/app'; （"Cannot find module, " firebase / app）

import { Router } from '@angular/router'; （"Cannot find module, " @ angular / router“）

这是我的app.module.ts文件，以防有用：

    看起来您的运营商仍然以rxjs 5.x方式链接 .

    那么回顾一下rxjs6中的变化：

    • 进口不同 . 现在，您应该以不同方式导入“rxjs / add / observable”中的Observable，Subject，BehaviorSubject等AND方法 . 所以这些都必须从'rxjs'导入 . 例如 ：

    import {Observable, Subject, of, from} from 'rxjs' ;

    或者，所有运算符，如map，concat，do（现在称为tap）等都将从 rxjs/operators 导入 . 像这样的东西：

    import { map, tap, takeUntil} from 'rxjs/operators';

    I think your imports are pretty sane.

    • 您必须使用管道而不是链接操作员 . 例如，在你的all-matches.components.ts第33行，如果你替换： this.authService.getCurrentUser().takeUntil(this.ngUnsubscribe).subscribe(user=>{

    通过

    this.authService.getCurrentUser().pipe(takeUntil(this.ngUnsubscribe)).subscribe(user=>{

    你的takeUntil错误将消失 .

    以相同的方式，而不是 Observable.of(true) ，您应该导入运算符并使用 of(true) .

    您可以在authorization.service.ts文件中尝试此操作 . 所有“错误”都将得到修复 .

    maybe you should inspect this

    • 关于自定义文件的导入错误，请检查实际存在的文件 . 例如 ：

    ERROR in src/app/app.module.ts(6,38): error TS2307: Cannot find module './api-keys'

    相关

    import { masterFirebaseConfig } from './api-keys'

    是正常的，因为此文件'./api-keys'不存在 . PS：如果密钥没有存储在git中，你可能没有这些错误，如果是这样，请忽略它 .

    • 最后，关于AngularFire5.0，你应该使用其中一个运算符：

    Db.list('items').subscribe(console.log)

    变为（使用valueChanges方法）：

    Db.list<Item>('items').valueChanges().subscribe(console.log)

    祝好运！
