我目前正在将现有的 Angular 项目从版本 11 更新到版本 16。我已成功过渡到版本 15，但在达到版本 16 时遇到了挑战。
我面临的问题是我的大多数模块都遇到以下错误消息：
“此导入包含错误，可能会影响依赖于此 NgModule 的组件。”
我的节点版本：16.16.0

我渴望学习和理解这个错误背后的潜在原因。有人可以解释一下为什么会发生这种情况吗？我们将非常感谢您的见解和指导。
从 v9 开始，Angular 由 Ivy 编译。当您使用旧版 Angular 编译器（View Engine）创建的库来编译应用程序时，会引发此错误。在 v16 之前，这还不是问题，因为 Angular 使用名为 ngcc 的工具为这些库提供了与 Ivy 的兼容性。
随着 ngcc 在 v16 中被正式删除https://github.com/angular/angular-cli/releases/tag/16.0.0，您要么必须为这些库找到更新的版本（与 Angular 兼容） Ivy）或更换它们。
仔细查看控制台，它可能会给您提供要查看的库。
