安装vue遇到的镜像问题

今天遇到个郁闷的问题，安装 npm install –global vue-cli 时，总是报如下错误(以前是可以的)，于是乎，删了装，装了删，用管理员登录，啥方法都试过了，就是没好使；连vue也报“不是内部或外部命令，也不是可运行的程序或批处理文件”，执行不了创建命令！

我有点儿怀疑是不是前两天翻墙闹的~~~

解决方法：

用了淘宝的npm镜像，所有安装用cnpm，问题解决

npm install -g cnpm –registry=https://registry.npm.taobao.org

cnpm install –global vue-cli

vue init webpack test

成功创建项目。(汗~~~~)
