Answer 1

看 log 啊，Please try running this command again as root/Administrator.
解决方法楼上给出了，命令前面加 sudo.

另外可以看看 http://stackoverflow.com/questions/16151018/npm-throws-error-without-sudo 这里。

Answer 2

安装过程中没有操作权限，使用管理员身份执行就可以了。
例如 sudo npm install xx

这样安装成功了 sudo npm install -g grunt-cli

Answer 4

我也遇到了一样的坑，用runas administrator账户就行。
cmd 里面输入runas /user:administrator cmd。
win7默认禁用的 administrator 帐号. lusrmgr.msc 开启

Answer 5

用管理员权限打开cmd命令框就可以了。
