npm ERR! publish Failed PUT 403

使用命令 npm publish 发布一个包时，或有如下报错：

...
npm ERR! publish Failed PUT 403
npm ERR! code E403
npm ERR! no_perms Private mode enable, only admin can publish this module:...
...

解决过程如下：

1. 检查仓库是否被设成了淘宝镜像库

npm config get registry

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

2. 如是，则设回原仓库

npm config set registry=http://registry.npmjs.org

3. 登录账号（如未登录）

npm login

Username: username
Password:  *
Email: (this IS public)
foo@bar.com Logged in as username on  http://registry.npmjs.org/.

4. 再次发布

npm publish

5. 如发布成功，则再次将仓库地址设为淘宝镜像地址

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