當在Rails應用程序中將Rails應用程序部署到Dreamhost時出現'意外的文件結束'

Question

我對Rails應用程序比較陌生，但我有一個本地工作的Rails應用程序，我試圖部署到共享在DreamHost上託管服務器。我已經關注了所有wiki和stackoverflow的問題，但是對此的回答仍然無法解決。

我使用Capistrano進行部署，並且已經制定出所有問題以便成功部署工作。然而，當我去訪問任何不是網站上的靜態資源，我招呼着一個「內部服務器錯誤」，並從客運此錯誤：

Internal server error 
Passenger encountered the following error: 
The application spawner server exited unexpectedly: Unexpected end-of-file detected. 

Exception class: 
PhusionPassenger::Rack::ApplicationSpawner::Error 
Backtrace: 
# File Line Location

11 /dh/passenger/lib/phusion_passenger/abstract_server.rb 206 in `start_synchronously' 
12 /dh/passenger/helper-scripts/passenger-spawn-server 99 

我可以SSH到服務器和手動運行'rails s'來獲得運行在3000端口上的服務器，並且所有工作都很好。

這裏是我的environment.rb：

# Load the rails application 
require File.expand_path('../application', __FILE__) 

# Initialize the rails application 
LoLItemDb::Application.initialize! 

# potential fix for Dreamhost shared resources

require 'rubygems/gem_runner' 
ENV['GEM_PATH'] = '/home/gravitydev/ruby/gems:/usr/lib/ruby/gems/1.8' 
Gem.clear_paths 

deploy.rb：

user = "XXXXXXXXX" 
domain = "XXXXXXXXX.com" 
database = "mysql.XXXXXXXXX.com" 

set :application, "XXXXXXXXX" 
set :rails_env, "production" 
set :use_sudo, false 

# set rake to be verbose for capistrano 
# http://stackoverflow.com/questions/7071126/how-can-i-run-rake-with-trace-within-capistrano 
set :rake, "#{rake} --trace" 

# here we set a custom paths to commands since on Dreamhost 
# servers the user path is a bit different 
set :bundle_cmd, "/home/#{user}/.gems/bin/bundle" 
require 'bundler/capistrano' 

# redirect path for whenever, and use bundler to execute it 
set :whenever_command, "/home/#{user}/.gems/bin/bundle exec whenever" 
require 'whenever/capistrano' 

# configure credentials

set :deploy_to, "/home/#{user}/#{domain}" 
set :scm, "git" 
set :scm_passphrase, "XXXXXXXXX"     # The deploy user's password 
set :scm_verbose, true 
set :git_shallow_clone, 1 

# configure deploy location 
set :deploy_to, "/home/#{user}/#{domain}" 

# setup web server 
server domain, :app, :web, :db, :primary => true 
#server domain, :app, :web 
#role :db, database, :primary => true 

# for SSH 
# see: http://wiki.dreamhost.com/Capistrano 
set :chmod755, "app config db lib public vendor script script/* public/disp*" 

# if you want to clean up old releases on each deploy uncomment this: 
after "deploy:restart", "deploy:cleanup" 

# run the all "LoL" tasks to refresh the database 
#after "deploy:restart", "lol:all" 

# if you're still using the script/reaper helper you will need 
# these http://github.com/rails/irs_process_scripts 

# for Passenger 
namespace :deploy do 
    task :restart do 
    run "touch #{current_path}/tmp/restart.txt" 
    end 
end 

和Gemfile中： 源 'https://rubygems.org'

gem 'rails', '3.2.6' 
gem 'bundler' 
gem 'rake' 
gem 'sqlite3' 
gem 'haml' 
gem 'nokogiri' 
gem 'json' 
gem 'whenever' 
gem 'execjs' 
gem 'therubyracer', :platforms => :ruby 
gem 'mysql2' 
gem 'rack' 
gem 'RedCloth', '4.2.9' 
gem 'jquery-rails' 
gem 'capistrano' 

# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'coffee-rails', '~> 3.2.1' 

    # See https://github.com/sstephenson/execjs#readme for more supported runtimes 
    # gem 'therubyracer', :platforms => :ruby 

    gem 'uglifier', '>= 1.0.3' 
end 

最帖子似乎表明寶石的路徑是不正確的，但我已經通過搜索找到了我可以找到的每個配置更改Google和來自Dreamhost的文檔。任何幫助是極大的讚賞！

Answer 1

與此亂搞相當長的一段時間後，有兩件事情使我的解決方案。首先，部署到Dreamhost的，當你需要重寫你的GEM_HOME路徑在config.ru像這樣：

# taken from https://discussion.dreamhost.com/thread-128599.html 
ENV['GEM_HOME'] = '/home/USERNAME/.gems' 
require 'rubygems' 
Gem.clear_paths 

此外，我從我開始思考我的Gemfile是需要的寶石，我並不需要abhas閱讀評論指定。基本上，我之前添加了它們來模擬我當地的寶石安裝，但發現我並不需要它們。我最後Gemfile看起來是這樣的：

source 'https://rubygems.org' 

gem 'rails', '3.2.6' 
gem 'bundler' 
gem 'rake' 
gem 'sqlite3' 
gem 'haml' 
gem 'nokogiri' 
gem 'whenever' 
gem 'mysql' 
gem 'mysql2' 
gem 'jquery-rails' 
gem 'capistrano' 

# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'coffee-rails', '~> 3.2.1' 

    # See https://github.com/sstephenson/execjs#readme for more supported runtimes 
    # gem 'therubyracer', :platforms => :ruby 

    gem 'uglifier', '>= 1.0.3' 
end 

完成這些修改後，乘客很高興，發現所有的寶石需要！感謝abhas讓我思考在正確的領域改變事物。

編輯：我會接受這個答案時的StackOverflow讓我:)

Answer 2

在你的Gemfile變化

這

gem 'RedCloth', :require => 'redcloth' 

它可能工作
