npm ERR! Error: EPERM: operation not permitted

在根据angular4官网的例子做时,安装完node.js和angular/cli后,进行新建项目 采用命令ng new my-app时,报如下错误

看错误貌似是权限问题,网上也有很多说权限问题,切换到管理员窗口即可,自己本身就是管理员权限,因而无用,,

最后症结是缓存问题导致:

解决办法如下

需要删除npmrc文件。

强调:不是nodejs安装目录npm模块下的那个npmrc文件

而是在C:\Users\{账户}\下的.npmrc文件..

当然也有说用命令清除缓存的,我自己试了下没成功,上面删除文件来的更加直接彻底,关键是见效,记录于此。
