angular - "You seem to not be depending on "@ Angular/核心 "."

Question

当我尝试构建我的项目时运行以下命令:

ng build --environment=prod --aot=false  --output-path="..." --base-href="..."

你似乎不依赖于 @angular/core。

这是一个错误，但是，我不明白为什么，因为之前它运行良好。

我试过这样做:

npm install @angular/core 

但是我得到这个错误:

error at Error (native) error { Error: EACCES: permission denied, chown '' error at Error (native) error errno: -13, error code: 'EACCES', error syscall: 'chown', error Please try running this command again as root/Administrator. verbose exit [ -13, true ]

我也尝试摆脱 node_modules，然后安装 npm: 但我得到了同样的错误。

当我运行以下命令时:

ng serve

我有另一个错误:

The "@angular/compiler-cli" package was not properly installed. Error: Error: Cannot find module '@angular/compiler-cli'

这是我的package.json:

不确定以下方法是否能解决您的问题，请尝试一次。

我在执行以下命令时也遇到了同样的问题。

D:\My_Project>ng serve

然后我按照以下步骤操作，它对我有用。

D:\My_Project>npm link
D:\My_Project>ng serve

如果这不起作用，请告诉我，我会尝试重现您遇到的错误并尽快为您提供解决方案。
