Question

首次使用Capistrano部署应用程序，但在运行cap deploy：在Rails 3.1.3，Capistrano 2.9.0，RVM 1.8.6和Ubuntu服务器10.10上运行更新任务时出现问题。就我所见，不应该是权限问题。现在已经对我的头撞了一会儿，感谢任何指示。

Answer 1

在开发盒和服务器上使用不同版本的RVM是一个问题，我没有set up deploy.rb properly与RVM一起工作。一直在挖掘几个小时，以为它是某种bug。哦，好吧。

让它在deploy.rb中使用它：

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

Answer 2

找不到rake二进制文件。如果您使用的是RVM，请确保您正在部署的用户位于rvm组中。

或者，很可能（或与上述相结合），您对非交互式shell禁用.bashrc / bashrc / profile环境。因此它不会加载所有配置（设置PATH等）。

请参阅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。最后一行是问题所在。它退出处理非交互式shell的bashrc。在你的系统上寻找类似的东西。
