Ruby on rails ubuntu用户&；ssh登录权限被拒绝的消息

我使用ubuntu 14.04设置我的应用程序环境。安装rbenv-ruby+rails，nginx+passenger，全部完成

但是当我想创建一个depoly用户 出什么事了！当我注销并与john一起登录（我成功登录）时，我收到以下消息，我是否更改了某些设置？我只是登录，而不是创建文件夹，所以这些消息很混乱，我现在没有权限（比如rails-v、ruby-v…等等）， 但是我仍然可以使用sudo做一些事情，比如sudovisudo

您的rbenv安装已损坏。完全卸载它：

rm -rf `rbenv root`

然后使用本地安装重新安装rbenv（使用deployer user），查看rbenv站点以获取说明：

生成的文件夹应该是/home/deployer/.rbenv，而不是/usr/local/rbenv
