Angular-CLI ng new:"错误:EPERM:不允许操作......"

Question

我正在尝试使用Angular-CLI安装新的Angular2应用程序,但仍然遇到以下问题:

ng new payment-calc-app

在"通过npm安装工具包"之后,我得到以下错误代码:

Package install failed, see above.

我尝试npm clean cache并以管理员身份运行命令提示符(我在Windows上)无济于事.

奇怪的是,当我尝试删除安装失败的文件夹时,Windows阻止我删除它们,说我需要成为管理员来删除它们,即使我是管理员.我需要进入每个单独的文件夹并一次删除一个单独的文件.

Answer 1

在我的情况下,问题是我有另一个'ng serve'运行的命令提示符,我停止了进程并且创建成功完成

Answer 2

• 使用命令: npm install -g @angular/cli --no-optional
• 关闭当前角度项目文件夹(在这种情况下payment-calc-app)
• 授予父文件夹读写权限和存档权限(右键单击父文件夹并授予文件夹和子
  文件夹权限)
  • NodeJs以管理员模式打开命令提示符
  • 运行命令 ng new payment-calc-app

亲爱的 Angular 2 程序员，为了生存，这个错误很痛苦，无法通过 npm 缓存清理、重新启动或其他我已知的方法解决...只需卸载以前的节点版本并安装新的当前版本@ https://nodejs。 org/en/download/current/ - 这解决了我机器上的错误..祝你好运！
