解決辦法：

設置npm代理地址，命令以下：

npm config set registry http://registry.cnpmjs.org

以前一直用的淘寶npm代理

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

切換回來，就不報錯。詳細原由不明白。

補充：把npm版本降級，實測能夠解決，可能5.0以上版本有微妙的問題

node v9.2.0
npm  v5.5.1

上面是我本機當前的環境信息，能夠把npm降級後試試，命令以下

npm i -g npm@4

再補充

使用 yarn 安裝
npm i -g yarn
