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

Question

当我们启动多个项目时，ng2中的3个和ng4中的1个，独立运行。一个项目也使用datatables.net。当试图整合和升级到ng4时，我得到了这个错误。

1. 登录是1个应用组件，和其他人使用的login.html - 什么是更好的方法？在编译

   类 '主题'

2. 错误错误地延伸的基类 '可观测'。 属性'lift'的类型不兼容。 类型'（operator：Operator）=> Observable'不可分配给类型'（operator：Operator）=> Observable'。 类型'Observable'不可分配为键入'Observable'。 类型'T'不可分配给'R'类型。

   解决版本 [rxjs已升级到5.4.2 - 和降级到5.0.1]

rxjs是版本5.4.2

提具体问题后，应用程序的工作是

Answer 1

此错误^ h伴随着TypeScript的升级。

您应该升级所有软件包。但有可能某些软件包没有进行最后的TypeScript修改。

然后，您可以对这些项目做出贡献以使其兼容，否则应降级到支持TypeScript 4.1的最后一个Angular 4版本。
