我和我的团队刚刚从Angular 7更新到Angular8。当我在执行“ git pull”更新本地存储库后尝试运行“ ng serve”时，我开始遇到执行问题。我被告知要删除我的node_module文件夹和package-locker.json文件，并在项目中运行npm install。突然问题开始了，由于显然是量角器程序包的依赖性，我不再能够运行我的应用程序。我警告大家，我在Stackoverflow上看到了一些可能的解决方案，但没有一个能够解决我的问题。
我按照建议尝试的解决方案：检查我的项目中是否存在任何量角器导入，例如从'量角器'导入{EventEmitter}。找不到。
以下是我的一些信息：
