想要在npm上发布自己的组件库，npm登录login时报错：npm ERR! code E401，npm ERR! Incorrect or missing password.

这是因为之前npm使用了淘宝镜像，淘宝镜像只支持下载，不支持上传发布，需要将配置的registry重新指向npm官方registryhttps://registry.npmjs.org/：

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

登录成功：

Logged in as qianmian on https://registry.npmjs.org/.

但是npm官方下载包很慢，再切换到淘宝镜像：

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