如上错误解决办法如下：
官方的解决方案：[https://docs.npmjs.com/getting-started/fixing-npm-permissions](https://docs.npmjs.com/getting-started/fixing-npm-permissions)
官方提供了两种解决方案：
重新安装一个node version manager。（官方推荐）
参考地址：[https://docs.npmjs.com/getting-started/installing-node](https://docs.npmjs.com/getting-started/installing-node)
注：这个方法比较繁琐，我选择的是第二种方案。
改变npm默认的路径。
步骤如下：
进入终端，依次输入一下命令
（1）创建global安装任务的目录
mkdir ~/.npm-global
（2）配置npm使用新的目录
npm config set prefix '~/.npm-global'
（3）在~/.profile文件中增加配置
export PATH=~/.npm-global/bin:$PATH
（4）配置文件立即生效
source ~/.profile
（5）重新执行命令
npm install -g xxxx
拆卸脚手架 然后安装
