在 ng serve 找不到模块“@angular/compiler-cli/ngcc”

Question

出于某种原因，我突然收到此错误。 这可能是angular-cli`的版本问题，但我找不到问题。 谢谢您的帮助！

npm i只显示一些警告，编译器就在那里。 如果我从对等依赖警告安装该特定版本，则下次执行npm i时会弹出另一个不同版本的版本，并且ng serve处的错误未解决。

这是我的package.json ：

删除依赖项版本中的所有^以便它锁定到该依赖项的特定版本（您的工作配置）。 当您执行npm install ，它将安装锁定版本。 ^表示：此版本或更高版本（如果可用）。 这将在未来引起冲突，因为依赖关系会发生很大变化。
