未经授权的npm安装操作

Question

我已成功登录我的私人npm存储库。但是，当我尝试从中安装软件包时，npm告诉我："Unauthorized You must log in to perform this action.: npm"。有什么想法吗？

1. npm --registry http://private.registry.com/npm/npm_unstable login - ＆gt; "Logged in as user on http://private.registry.com/npm/npm_unstable."
2. npm --registry http://private.registry.com/npm/npm_unstable install cest

.npmrc的内容：

http://private.registry.com/npm/npm_unstable=
//private.registry.com/npm/:_password="TDVuZRndGwwMD8="
//private.registry.com/npm/:username=user
//private.registry.com/npm/:email=user@private-registry.com
//private.registry.com/npm/:always-auth=false
