运行cap部署时的资产管道问题：Rails 3.1.3上的更新

Question

首次部署应用程序与Capistrano，但运行cap部署时出现问题：Rails 3.1.3，Capistrano 2.9.0，RVM 1.8.6上的更新任务和Ubuntu服务器10.10。就我所见，不应该是权限问题。现在一头撞过我的头，感谢任何方向。

Answer 1

这是对发展框和服务器的不同版本RVM的一个问题，我有而不是set up deploy.rb properly与RVM协同工作。一直在挖掘几个小时认为它是某种bug。好吧。

得到它的工作在deploy.rb使用此：

$:.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

它找不到耙子二进制。 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，最有可能（或与上述结合），您为非交互式shell禁用了.bashrc/bashrc/profile环境。因此它不会加载所有配置（设置PATH等）。

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

Debian的（在/ etc/bashrc中）：

# 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。它退出非交互式shell的处理bashrc。 在您的系统上寻找类似的东西。
