Answer 1

你沒依照官網給的去安啊。 registry 。 應該是npm install -g cnpm --registry=https://registry.npm.taobao.org

Answer 2

錯誤原因是這個：
unable to verify the first certificate
字面意思是跟證書有關係的
幫你百度了下：

Answer 3

Windows 下裝 cnpm 本來就比較慘，推薦使用 nrm 換 registry 方式使用 cnpm 來源。

Answer 4

推薦使用nrm，簡單無痛

$ npm i nrm -g
$ nrm ls
$ nrm use <你中意的源>
