【问题描述】：

我在这个问题上浪费了几天，我确信这是一个简单的解决方案，请帮助！当我在笔记本电脑上从我的用户帐户运行$ cap deploy:setup 时，我收到了下面粘贴的错误。 RVM 似乎有问题，但我知道它已安装，并且我已经预安装了我的应用程序所需的所有 gem。有没有其他人遇到过类似的错误？任何帮助将不胜感激！

【问题讨论】：

您使用的是什么版本的 RVM？可能值得更新，因为这个问题似乎相关：github.com/wayneeseguin/rvm/issues/586
您好，感谢您的回复。我正在使用 rvm 1.10.2。
您的配置似乎有问题，请发布 'set's for rvm
这个问题似乎已经意外解决了。不太确定我做了什么......但现在我遇到了另一个错误。我将发布一个包含新错误的帖子的链接。

【解决方案1】：

我刚刚遇到了这个问题，虽然我的安装抱怨：

out :: server]
** [out :: server] $rvm_path (/home/nebula/.rvm/) does not exist.
*** [err :: server] /usr/local/rvm/scripts/rvm: line 185: __rvm_teardown: command not found
*** [err :: server] /usr/local/rvm/bin/rvm: line 52: /home/nebula/.rvm//scripts/rvm: No such file or directory
*** [err :: server] Error sourcing RVM!
*** [err :: server] Error: RVM was unable to use 'ruby-1.9.3-p392'

我正在使用带有系统范围安装的 rvm（标准安装到 /usr/local/rvm）。将以下内容添加到我的 Capfile 解决了这个问题：

set :rvm_type, :system
set :rvm_path, "/usr/local/rvm"

【讨论】：

确实有效！作为一个脚注，我将补充说我首先使用了set :rvm_bin_path, "/usr/local/rvm/bin"，虽然这个信息是正确的（我确实有一个包含可执行文件的 bin 文件夹），但这一直给我同样的错误。当我将线路更改为set :rvm_path, "/usr/local/rvm"时，它工作得非常好。

【解决方案2】：

错误显示：RVM 无法使用“默认”gemset。意味着 RVM 找不到要使用的名为“默认”的 gemset。检查 deploy.rb 中的以下行

set :rvm_ruby_string, 'gemset-name-here'  => put a valid gemset here
