按照npm安装cnpm 的命令：
npm install -g cnpm --registry=https://registry.npm.taobao.org报错如果下：
npm WARN deprecated [email protected]: request has been deprecated, see https://github.com/request/request/issues/3142
npm WARN deprecated [email protected]: this library is no longer supported
npm ERR! path C:\Users\Administrator\AppData\Roaming\npm\node_modules\cnpm\node_modules\.bin\npm.cmd

npm ERR! File exists: C:\Users\Administrator\AppData\Roaming\npm\node_modules\cnpm\node_modules\.bin\npm.cmd

后查询了几篇博客，尝试如下：
npm config set registry https://registry.npm.taobao.org
npm config get registry
npm install nrm -g依旧毫无作用，继续报错：
无果，下午将电脑重启之后，在找到项目并打开了CMD，继续输入安装命令：
npm install cnpm -g --registry=https://registry.npm.taobao.org竟然自己好了，真难啊
最后还是强烈建议大家做vue项目能用cnpm install就不用npm install,毕竟是比较快捷方便，npm install 安装下来可能一个小时有时候还不一定，加油搬砖人！
