在Mac上安装淘宝镜像时遇到无权限问题，需使用sudo命令。输入安装命令并提供开机密码后，通过特定命令检查安装是否成功。成功标志是查看输出的最后几行代码显示正确。

安装淘宝镜像错误代码如下：

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

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

直接安装无权限，需要使用sudo命令来安装
安装命令如下：

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

回车！
接下来会提示Password，输入电脑开机密码即可，输入之后不显示任何符号直接输入完开机密码之后点击回车即可；

查看是否安装成功

查看最后几行代码

...
npm verb exit [ 0, true ]
npm timing npm Completed in 18992ms
npm info ok

使用命令查看

cnpm -v

输出如下即安装成功
