ruby-on-rails - ubuntu 用户和 ssh 登录权限被拒绝消息

Question

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

但是当我想创建一个 depoly 用户时
有事吗!当我注销并使用 john 登录时(我登录成功)，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，所以这个消息很困惑，我现在没有权限(比如 rails -v，ruby -v ......等)，
但我仍然可以使用 sudo 来执行 之类的操作须藤 visudo

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(使用部署者用户)，查看 rbenv 站点以获取说明:

https://github.com/sstephenson/rbenv#installation

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