我尝试将我的应用程序从rails 3.1.3升级到rails 3.2.1,我遇到资产问题.
ActionController::RoutingError (No route matches [GET] "/assets/logos/opera_logo.png"): actionpack (3.2.1) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/show_exceptions.rb:56:in `call' railties (3.2.1) lib/rails/rack/logger.rb:26:in `call_app' railties (3.2.1) lib/rails/rack/logger.rb:16:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/request_id.rb:22:in `call' rack (1.4.1) lib/rack/methodoverride.rb:21:in `call' rack (1.4.1) lib/rack/runtime.rb:17:in `call' activesupport (3.2.1) lib/active_support/cache/strategy/local_cache.rb:72:in `call' rack (1.4.1) lib/rack/lock.rb:15:in `call' actionpack (3.2.1) lib/action_dispatch/middleware/static.rb:53:in `call' railties (3.2.1) lib/rails/engine.rb:479:in `call' railties (3.2.1) lib/rails/application.rb:220:in `call' rack (1.4.1) lib/rack/content_length.rb:14:in `call' railties (3.2.1) lib/rails/rack/log_tailer.rb:14:in `call' rack (1.4.1) lib/rack/handler/webrick.rb:59:in `service' /usr/lib/ruby/1.9.1/webrick/httpserver.rb:111:in `service' /usr/lib/ruby/1.9.1/webrick/httpserver.rb:70:in `run' /usr/lib/ruby/1.9.1/webrick/server.rb:183:in `block in start_thread'
Rails没有找到我的所有资产,但我认为它们位于正确的文件夹中(例如app / assets / images / logos /).
我按照本指南升级了我的系统：http://railscasts.com/episodes/318-upgrading-to-rails-3-2?view=asciicast.使用rails 3.1运行得非常好.我没有找到任何其他改变.我能做什么？
这是我的Gemfile：
source 'http://rubygems.org' gem 'rails','3.2.1' # Bundle edge Rails instead: # gem 'rails',:git => 'git://github.com/rails/rails.git' gem 'sqlite3' # 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' gem 'uglifier','>= 1.0.3' end gem 'jquery-rails' # To use ActiveModel has_secure_password # gem 'bcrypt-ruby','~> 3.0.0' # Use unicorn as the web server # gem 'unicorn' # Deploy with Capistrano # gem 'capistrano' # To use debugger gem 'ruby-debug19',:require => 'ruby-debug' group :test do gem 'capybara','1.1.2' gem 'rspec-rails','2.8.1' gem 'autotest-rails','4.1.1' gem 'spork','0.8.5' gem 'factory_girl_rails','1.4.0' gem 'email_spec','1.2.1' gem 'cucumber-rails','1.2.1' gem 'launchy','2.0.5' gem 'pickle','0.4.10' gem 'database_cleaner','0.7.0' gem 'simplecov','0.5.4' gem 'simplecov-rcov','0.2.3' gem "mocha",'0.10.0' gem 'capybara-firebug','0.0.10' gem "prawn",'0.8.4' end group :development do gem "nifty-generators",'0.4.6' end gem 'active_reload','0.6.1' gem "galetahub-simple_captcha",'0.1.3',:require => "simple_captcha" gem 'authlogic','3.1.0' gem 'Meta_search','1.1.3' gem 'naive_bayes',:git => 'git://github.com/reddavis/Naive-Bayes.git'
这是我的开发.rb：
Onopia::Application.configure do # Settings specified here will take precedence over those in config/application.rb # In the development environment your application's code is reloaded on # every request. This slows down response time but is perfect for development # since you don't have to restart the web server when you make code changes. config.cache_classes = false # Log error messages when you accidentally call methods on nil. config.whiny_nils = true # Show full error reports and disable caching config.consider_all_requests_local = true config.action_controller.perform_caching = false # Don't care if the mailer can't send config.action_mailer.raise_delivery_errors = false # Print deprecation notices to the Rails logger config.active_support.deprecation = :log # Only use best-standards-support built into browsers config.action_dispatch.best_standards_support = :builtin # Do not compress assets config.assets.compress = false # Expands the lines which load the assets config.assets.debug = true # Raise exception on mass assignment protection for Active Record models config.active_record.mass_assignment_sanitizer = :strict # Log the query plan for queries taking more than this (works # with sqlite,MysqL,and Postgresql) config.active_record.auto_explain_threshold_in_seconds = 0.5 end
这是我的application.rb：
require File.expand_path('../boot',__FILE__)
# Pick the frameworks you want:
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "sprockets/railtie"
# require "rails/test_unit/railtie"
if defined?(Bundler)
# If you precompile assets before deploying to production,use this line
Bundler.require(*Rails.groups(:assets => %w(development test)))
# If you want your assets lazily compiled in production,use this line
# Bundler.require(:default,:assets,Rails.env)
end
module Onopia
class Application < Rails::Application
# Settings in config/environments/* take precedence over those specified here.
# Application configuration should go into files in config/initializers
# -- all .rb files in that directory are automatically loaded.
# Custom directories with classes and modules you want to be autoloadable.
# config.autoload_paths += %W(#{config.root}/extras)
# Only load the plugins named here,in the order given (default is alphabetical).
# :all can be used as a placeholder for all plugins not explicitly named.
# config.plugins = [ :exception_notification,:ssl_requirement,:all ]
# Activate observers that should always be running.
# config.active_record.observers = :cacher,:garbage_collector,:forum_observer
# Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
# Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
# config.time_zone = 'Central Time (US & Canada)'
# The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
# config.i18n.load_path += Dir[Rails.root.join('my','locales','*.{rb,yml}').to_s]
config.i18n.default_locale = :fr
# Configure the default encoding used in templates for Ruby 1.9.
config.encoding = "utf-8"
# Configure sensitive parameters which will be filtered from the log file.
config.filter_parameters += [:password]
# Enable the asset pipeline
config.assets.enabled = true
# Version of your assets,change this if you want to expire all your assets
config.assets.version = '1.0'
# Configure generators values. Many other options are available,# be sure to check the documentation.
#config.generators do |g|
# g.test_framework :rspec,:fixture => false
#end
config.action_mailer.default_url_options = { :host => 'localhost:3000' }
end
end
编辑：一个更好的例子.
我想查看此文件：

非常感谢,祝你有个愉快的一天.
解决方法
显然有些gem依赖被打破了,而bundle exec rails服务器应该解决这个问题.这应该在没有sudo的情况下运行…除非您通常使用root权限使用您的应用程序(这不是很好).检查rails根目录中的文件/文件夹权限,这些权限可能因先前误用sudo命令而被破坏.在开发过程中,您几乎不需要任何root权限.
除此之外,similar issues之前也出现过,答案是更新整个宝石集,主要是链轮和导轨.您的配置文件对我来说没问题,我无法重现错误.
如果这没有帮助,我会创建一个新的rails应用程序,检查在那里使用相同的gemset工作的资产管道,并手动交叉检查所有配置文件.
还有各种用于路由的调试工具,但首先尝试以上方法.
