问题及解法

登录问题

cnpm login

npm ERR! code E403
npm ERR! 403 403 Forbidden - PUT https://registry.npmmirror.com/-/user/org.couchdb.user:nihilwater - [FORBIDDEN] Public registration is not allowed
npm ERR! 403 In most cases, you or one of your dependencies are requesting
npm ERR! 403 a package version that is forbidden by your security policy.

解决办法: 更换镜像源，再进行修改，在发布包之后再将镜像源修改回去

npm config set registry https://registry.npmjs.org/
npm login 
  ...
npm config set registry http://registry.npm.taobao.org/
