安装材料设计后，由于 ngcc ，我无法编译角度代码。我附上了我的错误跟踪

Answer 1

@Iolabs，是的，这就是答案。并为我工作，并进行了一些调整。

好吧，我npm install @ng-bootstrap/ng-bootstrap 在 CLI上采用了类似的方法，但遇到了同样的问题。然后我尝试通过 npm 安装，仍然得到了类似的结果。

但是，我注意到当我再次使用 ng add 时，出现了一个新错误：

您尝试添加的包不支持原理图。您可以尝试使用不同版本的软件包或联系软件包作者以添加 ng-add 支持。

然后我： npm uninstall @ng-bootstrap/ng-bootstrap

并跑了： ng add @ng-bootstrap/ng-bootstrap

并且包像魅力一样工作仍然不确定包是如何破坏的。

另一件事：确保删除NgbModule.forRoot()，如果您正在使用angular9.x.x
