亲测有效！！!

在npm install项目(vue+nodejs)的时候，突然报了以下错误

$ npm install
npm WARN tarball tarball data for typescript@3.0.3 (sha1-SFOz4nXs2qJ/eP2kbcJzp+t
/wcg=) seems to be corrupted. Trying one more time.

npm ERR! If you believe this might be a permissions issue, please double-check t

npm ERR! permissions of the file and its containing directories, or try running
npm ERR! the command again as root/Administrator (though this is not recommended
).

解决方案如下
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。
