无法在 angular 5 项目上解析 rxjs/***

Question

我无法在亚马逊 ec2 上运行我的 angular 应用程序。 当我使用 environment.stage.ts 配置执行ng serve或ng serve -c stage时，我收到错误，如下面的屏幕截图所示。 在我的电脑上本地运行时不会出现该错误，并且项目编译没有错误。

rxjs 的版本是 5.5.5。

Angular、angular-cli 和 node 版本也在下面。

尝试仅导入 rxjs 而没有 observables

使用此命令安装 rxjs compact，它将安装与您正在使用的 Angular 版本兼容的最新版本的 rxjs。

npm install --save rxjs-compat
