Angular 新建组件初级问题！

Question

node.js，Angular CLI 已经安装。

cnpm install

应该是环境不对吧，各位帮忙指点一下！谢谢（搜不到）
ng g component product1

已经设置了：ng set --global warnings.versionMismatch=false

报错如下：
Your global Angular CLI version (1.4.9) is greater than your local
version (1.4.7). The local Angular CLI version is used.

To disable this warning use "ng set --global warnings.versionMismatch=false".

Answer 1

两个问题。

一是Angular Cli全局版本低于项目版本，这个警告可以忽略它，或者升级。

二是，关于 ELOOP: too many symbolic links encountered 的错误，我想应该是 cnpm 引起的，建立使用：

cnpm install --by=npm

或，直接：

npm install

Answer 2

删除node-modules下文件，并清空缓存，然后再使用npm安装
