Angular 2-4 SETUP无法在Windows上运行

Question

我是Angular 2/4的新手，在我跟随https://github.com/angular/angular-cli的命令之前它工作正常。我在我的机器上运行Angular 2-4。但是在一些Windows更新之后，我再也无法运行Angular了。它一直在说

我运行了以下命令并在github anugular CLI安装中执行了其他命令

>npm install -g @angular/cli or sometimes I ran npm install -g @angular/cli@latest
npm install
ng serve

当我运行npm install -g @ angular / cli时。这个消息得到了。

之后我跑了：

npm install 服务

我也按照https://github.com/angular/angular-cli

中的步骤进行操作

似乎无法正常工作

错误我在运行ng serve

时遇到错误

C:\Temp\angular\dynamicformjan72017>ng serve
'ng' is not recognized as an internal or external command,
operable program or batch file.

我已经包含了节点模块权限的屏幕抓取功能。 有人可以帮忙吗？我正在运行Windows 7专业人员

您的全局安装的@angular/cli软件包似乎无法正常运行。

您应该尝试卸载/重新安装或更改文件夹选项（只读）。通常，由于Windows上的读/写权限而导致EPERM错误。

此链接可帮助您正确执行此操作：https://github.com/angular/angular-cli#updating-angular-cli

npm uninstall -g @angular/cli 
npm cache clean
npm install -g @angular/cli
