必须从注入上下文中调用inject()

我试图将我的Angular应用程序导出为npm模块以供其他应用程序使用,但遇到了一些困难.我无法在互联网上的任何其他地方找到此错误,而且我的智慧结束了.

我按照本教程:https://medium.com/@nikolasleblanc/building-an-angular-4-component-library-with-the-angular-cli-and-ng-packagr-53b2ade0701e

我使用ng-packagr将我的应用程序导出为npm模块.我可以从准系统测试应用程序上的本地文件夹成功安装它,但无法让它显示我的应用程序.

错误:
