淘宝镜像配置

2.1 配置淘宝镜像

npm config set registry https://registry.npm.taobao.org

2.2 安装cnpm

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

通过cnpm -v检测

MacOs配置cnpm时报错

code EACCES

npm ERR! syscall access

npm ERR! path /usr/local/lib/node_modules

解决

1 permissions of the file and its containing directories, or try running
npm ERR! the command again as root/Administrator. 
2 文件及其包含的目录的权限，或尝试运行npm犯错!再次以root/管理员的身份执行该命令。

会报错是因为执行命令没有获取管理员权限，只需要在原有的命令前面加上sudo获取权限，然后回车时候需要输入管理员密码即可。

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

检验一下 cnpm -v

完成
