使用Capistrano部署Ruby on Rails应用程序 - cap deploy:setup失败

Question

我在这个问题上浪费了几天时间，我相信这是一个简单的解决方案，请帮忙！ 当我从我的笔记本电脑用户账户运行$ cap deploy:setup时，我会得到下面粘贴的错误。看来RVM有问题，但我知道已安装，也预先安装了我的应用程序将需要的所有宝石。是否有其他人遇到类似的错误？任何帮助都将不胜感激！

你使用的RVM版本是什么？由于这个问题似乎与此相关，因此更新可能是值得的：https://github.com/wayneeseguin/rvm/issues/586 - Christopher Manning

嗨，感谢您的回复。我正在使用rvm 1.10.2。 - J K

看起来是您配置的问题，请发布rvm的“set”设置。 - mpapis

这个问题似乎已经意外解决了。不太确定我做了什么...但现在我又出现了另一个错误。我将发布包含新错误的帖子链接。 - J K

虽然我的安装提示错误，但我遇到了这个问题：

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进行系统范围内的安装（标准安装至/usr/local/rvm）。在我的Capfile文件中添加以下内容解决了这个问题：

require 'capistrano/rvm'

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

确实有效！作为附注，我要补充一下，我最初使用了 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），但它仍然给了我相同的错误。当我将该行更改为 set :rvm_path, "/usr/local/rvm" 时，它完美地运行了。 - SylvainB

错误提示：RVM 无法使用 'default' gemset。这意味着 RVM 找不到要使用的名为 'default' 的 gemset。请检查您的 deploy.rb 文件中以下行：

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