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

大多数这些错误似乎都与rxjs有关，我认为这是正确的，因为我在更新中使用的是rxjs V.6，我的理解是在V.5和V.6之间有许多东西被破坏了。

我尝试安装rxjs-compatnpm install rxjs@6rxjs-compat@6--save，我可以确认这个包除了是一个很大的增加之外，并不能解决我看到的任何错误。

根据这里和这里的建议，我还通过运行ts-lint自动化了一些更新：

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

没有为JavaScript文件指定有效的规则

我猜这意味着我在使用RXJS时没有使用正确的ts约定？

当谈到rxjs时，我仍然相当不称职，所以我不清楚还需要重构什么。

从“@Angulation/Core”导入{Injectable,EventEmitter}；（“找不到模块，”@Angulation/Core“）

从“firebase/app”导入*作为firebase；（“找不到模块”，“firebase/app”）

从“@Angulation/Router”导入{Router}；（“找不到模块，”@Angulation/Router“）

看起来您的操作符仍然以RXJS5.x的方式链接。

因此，回顾一下rxjs6中的变化：

>

导入不同。现在，您应该导入Observable、Subject、BehaviorSubject等，以及在'rxjs/add/Observable'中不同的方法。所以所有这些都必须从'rxjs'导入。例如：

必须使用管道而不是链接运算符。例如，在all-matches.components.ts的第33行中，如果替换:this.authservice.getcurrentuser().takeIte(this.ngunsubscribe).subscribe(user=>{

由

this.authservice.getCurrentUser（）.pipe(TakeToil(this.ngunsubscribe)).subscribe(user=>{

您可以在authorization.service.ts文件中尝试此操作。所有的“错误”都将被修复。

也许你应该检查一下这个

关于自定义文件的导入错误，请检查文件是否存在。例如：

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

变为（使用valueChanges方法）：

db.list ('items').valueChanges().subscribe(console.log)
