设计 + Omniauth 无法在生产中工作

Question

我已经在我的应用程序中设置了设计。我想添加omniauth-facebook gem（用于facebook身份验证）。该设置在开发和暂存环境中运行良好，但在我的生产环境中出现以下错误：

Could not load 'omniauth'. Please ensure you have the omniauth gem >= 1.0.0 installed and listed in your Gemfile.
/home/slaxman/apps/itextbook/shared/bundle/ruby/1.9.1/gems/activesupport-3.2.11/lib/active_support/dependencies.rb:251:in `require': cannot load such file -- omniauth (LoadError)

这个警告似乎来自这个devise file。

我的Gemfile

source 'https://rubygems.org'

gem 'rails', '3.2.11'

group :production do
    gem 'pg', '0.14.1'
    gem 'therubyracer','0.11.4'
    gem 'execjs', '1.4.0'
end

group :assets do
    gem 'sass-rails',   '~> 3.2.6'
    gem 'jquery-rails', '~> 2.2.1'
    gem 'coffee-rails', '~> 3.2.2'
    gem 'uglifier', '~> 1.3.0'
    gem 'bootstrap-sass', '~> 2.3.1.2'
    gem 'bootswatch-rails', '~> 0.5.0'
end

gem 'unicorn', '~> 4.6.2'
gem 'capistrano', '~> 2.14.2'
gem "multi_json", "~> 1.2.0"
gem 'devise' , '~> 2.2.4'
gem 'omniauth-facebook', '1.4.0'
gem 'cancan', '~> 1.6.8'
gem 'omniauth', '>= 1.0.0'

user.rb

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable, :omniauthable,
         :recoverable, :rememberable, :trackable, :validatable
end

在devise.rb

中

config.omniauth :facebook, OMNIAUTH_VAR['FACEBOOK_APP_ID'], OMNIAUTH_VAR['FACEBOOK_APP_SECRET'], scope: 'email'

将以下内容添加到 devise.rb 也不起作用

require 'omniauth-facebook'
require 'omniauth'

任何帮助将不胜感激。谢谢！

Answer 1

解决了！显然，这是一个独角兽问题。重启独角兽没有帮助。需要使用以下命令手动停止和重启 unicorn：

/etc/init.d/unicorn_appname stop
/etc/init.d/unicorn_appname start

你也可以这样做：

sudo service unicorn_appname stop
sudo service unicorn_appname start

将“appname”替换为您的应用名称。

它的顺序可能不正确，这是我的 Gemfile 的一个示例。希望这会有所帮助。
