angular - 错误 TS2339 : Property 'takeUntil' does not exist on type 'Observable<Foo>' and other rxjs v. 6 个错误

我最近刚刚在我的 Angular 项目中更新了很多包。

旧的 package.json:

当我使用新的 package.json 更新运行 npm install 然后运行 ng serve 时，出现许多编译错误:

ERROR in src/app/all-matches/all-matches.component.ts(35,39): error TS2339: Property 'takeUntil' does not exist on type 'Observable'. src/app/app.component.ts(28,39): error TS2339: Property 'takeUntil' does not exist on type 'Observable'. src/app/authorization.service.ts(19,41): error TS2339: Property 'of' does not exist on type 'typeof Observable'. src/app/authorization.service.ts(29,37): error TS2339: Property 'of' does not exist on type 'typeof Observable'. src/app/authorization.service.ts(42,39): error TS2339: Property 'of' does not exist on type 'typeof Observable'. src/app/authorization.service.ts(66,39): error TS2339: Property 'of' does not exist on type 'typeof Observable'. src/app/authorization.service.ts(74,37): error TS2339: Property 'of' does not exist on type 'typeof Observable'. src/app/authorization.service.ts(82,39): error TS2339: Property 'of' does not exist on type 'typeof Observable'. src/app/database.service.ts(7,31): error TS2305: Module '"/Users/mf/Desktop/dataJitsu/node_modules/angularfire2/database/index"' has no exported member 'FirebaseListObservable'. src/app/database.service.ts(7,55): error TS2305: Module '"/Users/mf/Desktop/dataJitsu/node_modules/angularfire2/database/index"' has no exported member 'FirebaseObjectObservable'. src/app/match-display/match-display.component.ts(27,49): error TS2339: Property 'takeUntil' does not exist on type 'AngularFireObject<{}>'. src/app/new-match/new-match.component.ts(10,30): error TS2305: Module '"/Users/mf/Desktop/dataJitsu/node_modules/angularfire2/database/index"' has no exported member 'FirebaseListObservable'. src/app/new-match/new-match.component.ts(10,54): error TS2305: Module '"/Users/mf/Desktop/dataJitsu/node_modules/angularfire2/database/index"' has no exported member 'FirebaseObjectObservable'. src/app/new-match/new-match.component.ts(130,37): error TS2339: Property 'switchMap' does not exist on type 'Observable'. src/app/protection.guard.ts(14,34): error TS2339: Property 'map' does not exist on type 'Observable'. src/app/test-db/test-db.component.ts(7,30): error TS2305: Module '"/Users/mf/Desktop/dataJitsu/node_modules/angularfire2/database/index"' has no exported member 'FirebaseListObservable'. src/app/test-db/test-db.component.ts(7,54): error TS2305: Module '"/Users/mf/Desktop/dataJitsu/node_modules/angularfire2/database/index"' has no exported member 'FirebaseObjectObservable'. src/app/user-status-report/user-status-report.component.ts(28,39): error TS2339: Property 'takeUntil' does not exist on type 'Observable'. src/app/user-status-report/user-status-report.component.ts(33,45): error TS2339: Property 'subscribe' does not exist on type 'AngularFireObject<{}>'. src/app/user-status-report/user-status-report.component.ts(35,56): error TS2339: Property 'takeUntil' does not exist on type 'AngularFireObject<{}>'. src/app/user-status-report/user-status-report.component.ts(43,66): error TS2339: Property 'takeUntil' does not exist on type 'AngularFireObject<{}>'.

大多数这些错误似乎与 rxjs 有关，我认为这是正确的，因为我在更新中使用 rxjs v.6，我的理解是 v.5 和 v.5 之间有很多问题。 6.

我试着安装 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，没有解决我看到的任何错误。

根据建议 here，我还通过运行 ts-lint 自动执行了一些更新和 here :

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

我收到以下消息:

No valid rules have been specified for JavaScript files

我猜这意味着我在使用 rxjs 时没有使用正确的 ts 约定？

我在 rxjs 方面仍然很无能，所以我不清楚还有什么需要重构。

但我认为我的问题实际上发生在蠕虫的重构之前:

我看了一下第一个错误(

error TS2339: Property 'takeUntil' does not exist on type 'Observable'

一个)。错误来 self 的身份验证服务中的一个方法。在此服务顶部的导入语句中(以及大多数其他 .ts 文件，就此而言)，我的 IDE 突出显示了很多“找不到模块 foo”错误(例如，“找不到模块，'rxjs '"对于 import 语句，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”)

这是我的 app.module.ts 文件，以防有用:

最佳答案

看起来您的运算符仍然以 rxjs 5.x 方式链接。

所以回顾一下 rxjs6 中的变化:

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

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

或者，所有运算符，如 map、concat、do(现在称为 tap)等都将从 rxjs/operators 导入.所以像:

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

我认为您的导入非常明智。
您必须使用管道而不是链接您的运算符。例如，在您的 all-matches.components.ts 的第 33 行中，如果您替换: this.authService.getCurrentUser().takeUntil(this.ngUnsubscribe).subscribe(user=>{

由

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

您的 takeUntil 错误将消失。

以同样的方式，而不是Observable.of(true) ，您应该导入运算符并使用 of(true) .

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

也许你应该检查一下
关于自定义文件的导入错误，请检查文件是否确实存在。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，因为这个文件 './api-keys' 不存在。 PS:如果键没有存储在 git 中，也许你不会有这些错误，如果是这样忽略这个。
最后，关于 AngularFire5.0，您应该使用其中一种运算符:

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

变成(使用 valueChanges 方法):

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

祝你好运!
