当我开始运行我的应用程序时，我收到此错误：

我有这些版本： Angular CLI: 8.3.19 ， Node: 12.14.0 。

任何想法是什么导致了这个问题？

Answer 1

@angular-devkit/build-angular 似乎有问题。

尝试通过运行更新它

npm i @angular-devkit/build-angular

或者通过指定以前的版本来降级它，例如

npm i @angular-devkit/build-angular@0.803.24

在 npm audit 发现我正在使用的 @angular-devkit/build-angular 版本中存在漏洞之后，我遇到了这个错误。我运行了 npm audit fix 将其更新为 0.900.2 ，但是当我运行 ng serve 时，它给出了问题中引用的错误。

我通过降级到版本 0.803.25 解决了这个问题。这是我能找到的最高版本，它在运行时不会导致任何错误 ng serve 。 npm audit 发现的漏洞在此版本中得到解决。

这是我运行的命令：

 npm i @angular-devkit/build-angular@0.803.25
