错误当生产服务器

我试图部署与Capistrano的我的Rails应用程序在编译的资产，并得到了以下错误：错误当生产服务器

NoMethodError: undefined method `to_h' for nil:NilClass

这里是堆栈跟踪，它看起来像它可能是一个链轮的问题，但我想不通为什么：

这是我的本地环境：

OSX 10.11.3 
Ruby 2.1.3p242 
Rails 4.1.0 
Rake 10.3.2 
Sprockets-Rails 2.3.3 
Capistrano 3.4.0

这为m Ÿ生产环境：

Centos 5 
ruby 2.1.3p242 (managed by rbenv)

我当前安装的宝石：

bigdecimal (1.2.4) 
bundler (1.11.2) 
io-console (0.4.2) 
json (1.8.1) 
minitest (4.7.5) 
psych (2.0.5) 
rake (10.1.0) 
rdoc (4.1.0) 
test-unit (2.1.3.0)

我已经能够运行：

gem install bundler

但是，如果我运行：

gem install rails

我收到：

ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError) 
    bad response Service Unavailable 503 (https://api.rubygems.org/api/v1/dependencies?gems=rack)

这是否与我最初的问题有关？

您确定这不是Rubygems网站的简短故障吗？ – tadman

“对于nil：NilClass”未定义的方法'to_h'“并没有说明什么。它也应该告诉你行号和它发生的文件。你有一个未初始化的值，但我们不知道它会是什么。 –

您发布了无用的部分日志，并且这部分是在ruby 1.9.1下运行的。也许这是抓住？ –

对于任何遇到此问题的人来说，由于@ DavidK-J发布的链接指出我的方向正确，问题得到解决。我需要更新与rbenv设置的上限文件内容如下：

Capfile

require 'capistrano/rbenv'

deploy.rb

set :rbenv_type, :system 
set :rbenv_path, '~/.rbenv' 
set :rbenv_ruby, "2.1.3" 
set :rbenv_prefix, "RBENV_ROOT=#{fetch(:rbenv_path)} RBENV_VERSION=#{fetch(:rbenv_ruby)} #{fetch(:rbenv_path)}/bin/rbenv exec" 
set :rbenv_map_bins, %w{rake gem bundle ruby rails} 
set :rbenv_roles, :all

我只好再更新乘客的配置与路径rbenv哪些在我的情况是：

~/.rbenv

HTH别人。
