"你似乎不依赖于"@ angular/core"."

Question

当我尝试构建运行以下命令的项目时:

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

你似乎不依赖@angular/core.

这是一个错误,但是,我不明白为什么因为它之前运作良好.

我试着这样做:

npm install @angular/core 

但我得到这个错误:

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 ]

我也试图摆脱node_modules,然后安装npm:但我得到同样的错误.

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:

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

如果这不能正常工作,请告诉我,我将尝试重现您所获得的错误,并尽快给您解决方案.

Answer 2

如何使用

在此项目文件夹中运行"npm install"以安装所有依赖项.

确保使用最新版本的CLI(下面的升级指南)

运行"ng serve"以查看应用程序的运行情况(如果"ng serve"失败,请尝试"npm start").

如何升级CLI

运行以下命令 - 仅在Mac/Linux上使用"sudo".

sudo npm卸载-g angular-cli @ angular/cli

npm cache clean --force

sudo npm install -g @ angular/cli

如果它失败了

从项目目录中删除'node_modules'文件夹和'package-lock.json'文件按给定顺序运行以下命令 -

npm安装

npm install --save-dev @ angular-devkit/build-angular

npm链接

Answer 3

我按照终端中的提示在安装各种依赖项的列表中找到了。我在 Windows 上运行，所以我还安装了 Windows 构建工具。

我运行 ng serve 并得到“你似乎不依赖于“@angular/core”和/或“rxjs”。这是一个错误。

然后跑了

npm link

其次是

ng serve

现在一切都在运行。不确定我所做的有多少是必要的/多余的，但我现在可以构建 Angular 项目。
