当我使用新的package.json更新运行
npm install
,然后运行ng serve
时,我会得到许多编译错误:src/app/all-matches/all-matches.component.ts(35,39):错误 TS2339:类型“Observable”上不存在属性“takeUntil”。 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:类型“typeof Observable”上不存在属性“of”。 src/app/authorization.service.ts(29,37):错误TS2339:类型“typeof Observable”上不存在属性“of”。 src/app/authorization.service.ts(42,39):错误TS2339:类型“typeof Observable”上不存在属性“of”。 src/app/authorization.service.ts(66,39):错误TS2339:类型“typeof Observable”上不存在属性“of”。 src/app/authorization.service.ts(74,37):错误TS2339:类型“typeof Observable”上不存在属性“of”。 src/app/authorization.service.ts(82,39):错误TS2339:类型“typeof Observable”上不存在属性“of”。 src/app/database.service.ts(7,31):错误TS2305:“/Users/mf/Desktop/dataJitsu/node_modules/angularfire2/database/index”模块没有导出“FirebaseListObservable”成员。 src/app/database.service.ts(7,55):错误TS2305:“/Users/mf/Desktop/dataJitsu/node_modules/angularfire2/database/index”模块没有导出“FirebaseObjectObservable”成员。 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:“/Users/mf/Desktop/dataJitsu/node_modules/angularfire2/database/index”模块没有导出“FirebaseListObservable”成员。 src/app/new-match/new-match.component.ts(10,54):错误TS2305:“/Users/mf/Desktop/dataJitsu/node_modules/angularfire2/database/index”模块没有导出“FirebaseObjectObservable”成员。 src/app/new-match/new-match.component.ts(130,37):错误TS2339:类型“Observable”上不存在属性“switchMap”。 src/app/protection.guard.ts(14,34):错误TS2339:类型“Observable”上不存在属性“map”。 src/app/test-db/test-db.component.ts(7,30):错误TS2305:“/Users/mf/Desktop/dataJitsu/node_modules/angularfire2/database/index”模块没有导出“FirebaseListObservable”成员。 src/app/test-db/test-db.component.ts(7,54):错误TS2305:“/Users/mf/Desktop/dataJitsu/node_modules/angularfire2/database/index”模块没有导出“FirebaseObjectObservable”成员。 src/app/user-status-report/user-status-report.component.ts(28,39):错误TS2339:类型“Observable”上不存在属性“takeUntil”。 src/app/user-status-report/user-status-report.component.ts(33,45):错误TS2339:类型“AngularFireObject<{}>”上不存在属性“subscribe”。 src/app/user-status-report/user-status-report.component.ts(35,56):错误TS2339:类型“AngularFireObject<{}>”上不存在属性“takeUntil”。 src/app/user-status-report/user-status-report.component.ts(43,66):错误TS2339:类型“AngularFireObject<{}>”上不存在属性“takeUntil”。
大多数错误似乎与rxjs有关,我认为是正确的,因为我在更新中使用了rxjs v.6,并且我的理解是,在v.5和v.6之间许多事情都被破坏了。
我尝试安装rxjs-compat
npm install rxjs@6 rxjs-compat@6 --save
,但我可以确认这个包除了增加一些负担外,没有解决我看到的任何错误。我还根据这里和这里的建议运行了ts-lint来自动更新。
npm i -g rxjs-tslint
rxjs-5-to-6-migrate -p [path/to/tsconfig.json]
我收到了以下信息:
JavaScript文件没有指定有效的规则
我猜这意味着在使用rxjs时我没有使用正确的ts约定?
当涉及到rxjs时,我还是很无能的,所以我不太清楚需要重构什么。
但我认为我的问题实际上出现在重构之前:
我查看了第一个错误(
错误TS2339:类型“Observable”上不存在属性“takeUntil”
)。 这个错误来自于我的身份验证服务中的一个方法。 在此服务的导入语句中(以及大多数其他.ts文件),我的IDE突出显示了许多“找不到模块foo”的错误(例如,“找不到模块'rxjs'”对于导入语句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“)

这是包含所有这些问题的存储库分支。
git clone https://github.com/Atticus29/dataJitsu.git
cd dataJitsu
git checkout version-hell-SO
npm install
ng serve
