我正在尝试使用capifony进行部署，但是当我运行时
$ cap deploy
它返回错误

我还有另外一个问题，在部署失败后，有没有办法在下面做这行？
executing "rm -rf /home/yamaken/som.info/releases/20131204024539; true"
如果我可以保留服务器上的文件。我可以通过手动操作检查原因。
答案 0 :(得分：2)
调试Capistrano部署：
我想出一个简化调试的小技巧是使用环境变量来打开和关闭详细输出和一些额外信息。
您可以向deploy.rb添加类似内容（如果您愿意，可以延长或缩短）...
unless ENV['_DEBUG'].nil?
puts "Ruby Version => #{RUBY_VERSION}-p#{RUBY_PATCHLEVEL}"
puts "OpenSSL::Version => #{OpenSSL::OPENSSL_VERSION}"
puts "Net::SSH::Version::CURRENT => #{Net::SSH::Version::CURRENT}"
puts "Net::SSH -> Local platform => #{Net::SSH::Authentication::PLATFORM}"
puts "Remote Whoami => #{capture 'whoami'}"
puts "umask on Server => #{capture 'umask'}"
puts "$SHELL => #{capture 'echo $SHELL'}"
puts "$BASH_VERSION => #{capture 'echo $BASH_VERSION'}"
puts "Interactive Shell - Test: $PS1 => #{capture 'if [ -z "$PS1" ]; then echo no; else echo yes; fi'}"
logger.level = Logger::MAX_LEVEL
ssh_options[:verbose] = :debug
end
现在执行：
_DEBUG=1 cap deploy
