Angular 2 到 4 - Rxjs 中的错误 Subject.d.ts

Question

当我们启动多个项目时，在 ng2 中有 3 个，在 ng4 中有 1 个，它们都独立工作。一个项目也使用 datatables.net。当尝试集成并全部升级到 ng4 时，出现此错误。

登录是 1 个应用程序中的一个组件，其他人使用 login.html - 什么是更好的方法？
编译错误

Class 'Subject' incorrectly extends base class 'Observable'. Types of property 'lift' are incompatible. Type '(operator: Operator) => Observable' is not assignable to type '(operator: Operator) => Observable'. Type 'Observable' is not assignable to type 'Observable'. Type 'T' is not assignable to type 'R'.

Answer 1

TypeScript 升级时出现此错误。

您应该升级所有软件包。但是有可能有些包没有采用最后的 TypeScript 修改。

然后你可以为这些项目做出贡献，使它们兼容，或者你应该降级到支持 TypeScript 4.1 的最后一个 Angular 4 版本。
