今天安装cnpm失败，报这个错误：
npm WARN deprecated socks@1.1.10: If using 2.x branch, please upgrade to at least 2.1.6 to avoid a serious bug with socket data flow and an import issue introduced in 2.1.0
npm ERR! Unexpected end of JSON input while parsing near '..."},"directories":{},"'

解决办法：
npm set registry https://registry.npm.taobao.org // 注册模块镜像
npm set disturl https://npm.taobao.org/dist // node-gyp 编译依赖的 node 源码镜像
npm cache clean --force // 清空缓存
npm install -g cnpm --registry=https://registry.npm.taobao.org
