Angular 2-4 SETUP 无法在 Windows 上运行

Question

我是 Angular 2/4 的新手，在我遵循 https://github.com/angular/angular-cli 的命令之前它运行良好。我在我的机器上运行 Angular 2-4。但是在一些 Windows 更新之后，我不再能够运行 Angular。它一直在说

我在 github anugular CLI 安装中运行了以下命令并执行了其他命令

>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。这是下面的消息。

之后我跑了：

npm 安装 服务

我也按照这里的步骤https://github.com/angular/angular-cli

似乎没有任何效果

错误我在运行ng serve时遇到错误

C:\Temp\angular\dynamicformjan72017>ng serve

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

您的全局安装的@angular/cli 包似乎无法正常工作。

您应该尝试卸载/重新安装它或更改文件夹选项（只读）。通常EPERM错误是由于windows的读/写权限引起的。

此链接将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
