运行 cap deploy 时的资产管道问题：Rails 3.1.3 上的更新

Question

首次使用 Capistrano 部署应用，但在 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。据我所知，不应该是权限问题。一段时间以来一直在为此努力，感谢任何指示。

Answer 1

这是开发盒和服务器上不同版本的 RVM 的问题，我没有 set up deploy.rb properly 使用 RVM。挖了好几个小时，以为是某种bug。哦，好吧。

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

它找不到 rake 二进制文件。 如果您使用的是 RVM，请确保您部署的用户在 rvm 组中。

或者，很可能（或与上述情况相结合），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 (/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。
