我创建了一个包含项目中服务的Angular库 我已经在项目中导入了库，并且没有任何问题进行测试。
但是当我试图为我的角度项目进行AOT构建时 出现此错误

这是解决问题的脚本 ＆＃34;建立：AOT：PROD：基地＆＃34;
当我删除此标记＆＃34; cross-env BUILD_AOT = 1＆＃34;从脚本开始工作，但是在生产中运行app时我需要这个。

我会搜索您的代码以获取对SimpleAuthService的引用。
感谢Igor关于循环依赖关系的问题，例如：小心如何使用桶，例如fileA导入SimpleAuthService，它还导入一个index.ts，它导入SimpleAuthService或其他循环关系。在这种情况下，一种方法可能是明确导入某些项目而不是通过桶。
注意：在AOT期间，您通常会遇到更多编译问题，这是一件好事！即在开发周期中使用AOT编译时的良好做法，以确保它已准备好进行PROD构建。 AOT抓住了合法的问题。
