錯誤當生產服務器

我試圖部署與Capistrano的我的Rails應用程序在編譯的資產，並得到了以下錯誤：錯誤當生產服務器

NoMethodError: undefined method `to_h' for nil:NilClass

這裏是堆棧跟蹤，它看起來像它可能是一個鏈輪的問題，但我想不通爲什麼：

這是我的本地環境：

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

這爲m Ÿ生產環境：

Centos 5 
ruby 2.1.3p242 (managed by rbenv)

我當前安裝的寶石：

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)

我已經能夠運行：

gem install bundler

但是，如果我運行：

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)

這是否與我最初的問題有關？

您確定這不是Rubygems網站的簡短故障嗎？ – tadman

「對於nil：NilClass」未定義的方法'to_h'「並沒有說明什麼。它也應該告訴你行號和它發生的文件。你有一個未初始化的值，但我們不知道它會是什麼。 –

您發佈了無用的部分日誌，並且這部分是在ruby 1.9.1下運行的。也許這是抓住？ –

對於任何遇到此問題的人來說，由於@ DavidK-J發佈的鏈接指出我的方向正確，問題得到解決。我需要更新與rbenv設置的上限文件內容如下：

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與路徑rbenv哪些在我的情況是：

~/.rbenv

HTH別人。
