迁移到angular 8时的依赖关系问题

我尝试将一个应用程序迁移到angular 8，但现在当我运行我的应用程序时，我的package.json中有一个依赖性问题

更新angular/cli后，启动应用程序时，我收到以下消息：

处理请求时发生未处理的异常。 AggregateException:发生了一个或多个错误。（发生了一个或多个错误>。（NPM脚本“start”退出，但未指示Angular>CLI正在侦听请求。错误输出为：发生未处理的异常>：找不到模块'@Angular/compiler CLI/ngcc'

这是我的package.json文件

我无法解决此问题，也不知道哪些依赖项有问题，以及为什么要更改

 "start": "ng serve",
 "build": "ng build --extract-css",

请参阅

您尚未更新任何其他软件包。请尝试使用

ng update--all

命令更新所有Angular文件。@WillAlexander我收到以下消息：

找到不兼容的对等依赖项。安装依赖项时，对等依赖项警告意味着这些依赖项可能无法正确工作。您可以n使用“--force”选项忽略不兼容的对等依赖项，而代之以稍后解决这些警告。

答案在消息中。很抱歉，我不清楚，当我执行此命令时，我收到此消息消息消息消息说您可以使用

--force

标志，然后解决这些依赖项。因此，请继续执行此操作^^
