首次使用Capistrano部署应用程序，但是在Rails 3.1.3，Capistrano 2.9.0，RVM 1.8.6和Ubuntu服务器10.10上运行cap deploy：update任务时遇到问题。 就我所知，这不应是权限问题。 现在，我一直对此感到震惊，感谢任何指示。

这是开发箱和服务器上不同版本的RVM的问题，并且我没有正确设置deploy.rb以使其与RVM一起使用。 经过数小时的挖掘，认为这是一种错误 。 那好吧。

在deploy.rb中使用以下命令使其正常工作： 

$:.unshift(File.expand_path('./lib', ENV['rvm_path']))
require "rvm/capistrano"
set :rvm_ruby_string, 'ruby-1.9.2-p290'
set :rvm_type, :user

它找不到rake二进制文件。 如果使用的是RVM，请确保要部署的用户保持在rvm组中。

或者，很可能（或与上述结合使用），您为非交互式外壳禁用了.bashrc / bashrc / profile环境。 因此，它不会加载所有配置（设置PATH等）。

参见http://lists.apple.com/archives/macos-x-server/2008/Jun/msg00251.html

Debian（/ etc / bashrc）： 

# System-wide .bashrc file for interactive bash(1) shells.

# To enable the settings / commands in this file for login shells as well,
# this file has to be sourced in /etc/profile.

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

...等等。 最后一行是问题。 退出非交互式shell的处理bashrc。 在您的系统上寻找类似的东西。
