    当我跑步时 npm install 使用新的package.json更新,然后 ng serve ,我得到许多编译错误:

    src/app/all matches/all matches.component.ts(35,39)中出错:错误 TS2339:类型上不存在属性“takeUntil” “可观察”。src/app/app.component.ts(28,39):错误ts2339: 类型“Observable”上不存在属性“TakeUntil”。 src/app/authorization.service.ts(19,41):错误ts2339:属性'of' “typeof observable”类型上不存在。 src/app/authorization.service.ts(29,37):错误ts2339:属性'of' “typeof observable”类型上不存在。 src/app/authorization.service.ts(42,39):错误ts2339:属性'of' “typeof observable”类型上不存在。 src/app/authorization.service.ts(66,39):错误ts2339:属性'of' “typeof observable”类型上不存在。 src/app/authorization.service.ts(74,37):错误ts2339:属性'of' “typeof observable”类型上不存在。 src/app/authorization.service.ts(82,39):错误ts2339:属性'of' “typeof observable”类型上不存在。 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”' 没有导出成员“FireBaseObjectObservable”。 src/app/match display/match display.component.ts(27,49):错误TS2339: 类型“angularFireObject<>”上不存在属性“takeUntil”。 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”' 没有导出成员“FireBaseObjectObservable”。 src/app/new match/new match.component.ts(130,37):错误TS2339: 属性“switchmap”在类型“observable”上不存在。 src/app/protection.guard.ts(14,34):错误ts2339:属性“map”为 “observable”类型上不存在。 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”' 没有导出成员“FireBaseObjectObservable”。 src/app/user status report/user status report.component.ts(28,39): 错误TS2339:类型上不存在属性“takeUntil” “可观察”。 src/app/user status report/user status report.component.ts(33,45): 错误TS2339:类型上不存在属性“subscribe” 'AngularFireObject<>'。 src/app/user status report/user status report.component.ts(35,56): 错误TS2339:类型上不存在属性“takeUntil” 'AngularFireObject<>'。 src/app/用户状态报告/用户状态报告.component.ts(43,66): 错误TS2339:类型上不存在属性“takeUntil” 'AngularFireObject<>'。

    这些错误中的大多数似乎都与RXJS有关,我认为这是正确的,因为我在更新中使用了RXJS V.6,我的理解是许多东西在V.5和V.6之间被破坏了。

    我玩过安装RXJS Compat npm install rxjs@6 rxjs-compat@6 --save 我可以确认这个包,除了作为一个重要的附加,不能解决我看到的任何错误。

    根据建议,我还通过运行ts lint实现了一些更新的自动化。 here 和 here 以下内容: 

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

    我收到以下信息:

    没有为javascript文件指定有效的规则

    我猜这意味着我在使用RXJS时没有使用合适的TS约定?

    在RXJS方面,我仍然相当无能,所以我不清楚还需要重构什么。

    但我认为我的问题实际上发生在蠕虫重构之前:

    我看了一下第一个错误

    错误TS2339:类型“Observable”上不存在属性“TakeUntil”

    一个)。错误来自我的身份验证服务中的一个方法。在该服务顶部的import语句(以及其他大多数.ts文件)中,我的IDE突出显示了许多“找不到模块foo”错误(例如,import语句的“找不到模块”、“rxjs”), import { Observable } from 'rxjs'; )。

    同一文件中的类似错误:

    import { Injectable, EventEmitter } from '@angular/core'; (“找不到模块,”@angular/core“)

    import * as firebase from 'firebase/app'; (“找不到模块”,firebase/app)

    import { Router } from '@angular/router'; (“找不到模块,”@angular/router”)

    以下是我的app.module.ts文件,以防有用:

    看起来您的运营商仍然以RxJS5.x的方式被链接。

    1. 进口是不同的。现在,您应该导入Observable、Subject、BehaviorSubject等,以及不同于“rxjs/add/observable”中的方法。所以所有这些都必须从“rxjs”导入。例如:

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

      或者,所有操作符,如map、concat、do(现在称为tap)等,都将从导入 rxjs/operators

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

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

      通过

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

      Observable.of(true) of(true) .

    3. 关于自定义文件的导入错误,请检查文件是否实际存在。例如:

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

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

      是正常的,因为文件“./api keys”不存在。

    4. 最后,关于angularfire5.0,您应该使用以下运算符之一:

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

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

      https://github.com/angular/angularfire2/blob/master/docs/version-5-upgrade.md

    祝你好运!
