運行cap部署時的資產管道問題：Rails 3.1.3上的更新

Question

首次部署應用程序與Capistrano，但運行cap部署時出現問題：Rails 3.1.3，Capistrano 2.9.0，RVM 1.8.6上的更新任務和Ubuntu服務器10.10。就我所見，不應該是權限問題。現在一頭撞過我的頭，感謝任何方向。

Answer 1

這是對發展框和服務器的不同版本RVM的一個問題，我有而不是set up deploy.rb properly與RVM協同工作。一直在挖掘幾個小時認爲它是某種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

它找不到耙子二進制。 如果您使用的是RVM，請確保您正在部署的用戶位於rvm組中。

或者，最有可能（或與上述結合），您爲非交互式shell禁用了.bashrc/bashrc/profile環境。因此它不會加載所有配置（設置PATH等）。

見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。 最後一行是問題所在。它退出非交互式shell的處理bashrc。 在您的系統上尋找類似的東西。
