使用 capistrano 在 Rails 应用程序上部署 ruby​​ - cap 部署：安装失败

Question

我在这个问题上浪费了几天时间，我确信这是一个简单的解决方案，请帮忙！ 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。还有其他人遇到过类似的错误吗？任何帮助将不胜感激！

我刚刚遇到这个问题，尽管我的安装抱怨：

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 rvm 进行系统范围的安装（标准安装到 /usr/local/rvm）。将以下内容添加到我的 Capfile 中解决了该问题：

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

错误显示：RVM 无法使用“默认”gemset。意味着 RVM 无法找到名为“default”的 gemset 来使用。检查deploy.rb中的以下行

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