我是Angular的新手，并在ASP.Net MVC项目中实现了BABY STEP。我从github和最新的打字稿 v 3.2.2.0 为Visual Studio 2015更新3.我从类型中获得以下错误属性提升'的主题，在'中，我在''and typecrip v 3.2.2.0 下载了Angular快速启动3.基本类型可观察'。
other version used:
npm -v is 6.4.1
node -v is 10.15.2
我从github下载的package.json具有对旧版本的引用。附件是我正在使用的package.json文件。
我正在运行npm，并且能够通过Lift-Server托管网站。
错误ts2416：类型为"主题"中的属性"提升"是不可分配的 在基本类型"可观察"中使用相同的属性。输入'（操作员： 运算符）=>可观察到的'无法分配给类型 '（操作员：操作员）=>可观察到'。键入"可观察" 不能分配"可观察到"。类型" T"是不可分配的 键入'r'
请帮助。

}尝试升级：
npm install --save rxjs@^6.4.0此问题应该在RXJS 6中解决。
这里有几件事。
首先，您的打字稿在最新版本上。我不确定Angular 7都支持打字稿3.2.2。我认为当Angular 8很快发布时，它们会。其次，您的角包装已过时。如果可能的话，您应该更新到Angular 7。
第三，Visual Studio有时会对您的TS配置变得挑剔。如果以上两个不起作用，请发布您的TS配置，以便我们查看。我从vs 2017中的Web表单模板构建了角度应用程序。我使用Angular CLI而不是任何VS扩展名。如果您想要更多细节，请告诉我。
这是我最近开始的一个项目的包装：
