Heroku忽略pg gem

Question

我試圖將我的應用的新版本部署到heroku。部署失敗，因爲heroku說，gem pg不在我的GEMFILE中......我在我的GEMFILE中有這個postgres gem。我也尋找一些答案，但沒有人工作......任何人都有想法？

我使用Ruby 2.0.0p247，Rails的3.2.14煉油廠CMS 2.1.0

這裏是我的Gemfile：

source 'https://rubygems.org' 
ruby '2.0.0' 

gem 'rails' 
gem 'newrelic_rpm' 

group :production do 
    gem 'pg' 
    gem 'fog' 
end 

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

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

    gem 'uglifier', '>= 1.0.3' 
end 

gem 'jquery-rails' 

# To use ActiveModel has_secure_password 
# gem 'bcrypt-ruby' 

# To use Jbuilder templates for JSON 
gem 'jbuilder' 

# Use unicorn as the app server 
gem 'unicorn' 

# Deploy with Capistrano 
gem 'capistrano' 

# To use debugger 
gem 'debugger' 

# The Heroku gem allows you to interface with Heroku's API 
gem 'heroku' 

# Fog allows you to use S3 assets (added for Heroku) 
gem 'fog' 

# Postgres support (added for Heroku) 
#gem 'pg' 

#Connecting to Amazon S3 
gem 'aws-s3' 
#gem 'taps' 

# Refinery CMS 
#gem 'refinerycms', '~> 2.0.0', :git => 'git://github.com/refinery/refinerycms.git', :branch => '2-0-stable' 
gem 'refinerycms' 

# Specify additional Refinery CMS Extensions here (all optional): 
gem 'refinerycms-i18n' 
# gem 'refinerycms-blog', '~> 2.0.0' 
# gem 'refinerycms-inquiries', '~> 2.0.0' 
# gem 'refinerycms-search', '~> 2.0.0' 
gem 'refinerycms-page-images' 

gem 'refinerycms-announcements', :path => 'vendor/extensions' 
gem 'refinerycms-publications', :path => 'vendor/extensions' 
gem 'refinerycms-workers', :path => 'vendor/extensions' 

而且這裏的錯誤消息：

Answer 1

噢不...解決方案是刪除我的git回購並創建一個新的。我不知道爲什麼，但我的回購混亂了（我添加了新的文件等），所以它沒有提交所有數據。在chucknelson的尖端之後，我試圖鎖定某個rails版本，並發現heroku沒有得到這個。

Answer 2

根據gemfile：

# Postgres support (added for Heroku) 
#gem 'pg' 

pg已被註釋掉。取消它的註釋來安裝它

gem 'pg' 

在我的gemfile例如，我在Windows上工作，而且heroku沒有。所以，我有

gem "pg", '~> 0.15.1', :group => :production 
group :development, :test do 
    gem 'pg', "~> 0.15.1", :platform => [:mswin, :mingw] 

，因爲你必須安裝一些分貝，preferbly皮克因爲它的Heroku

也作爲加文在評論中說 - 確保你是在生產，因爲它似乎的Heroku沒有按沒想到O ..

Answer 3

問題是你在生產組中有PG的寶石。因此，當資產在Heroku上預編譯（使用全局組+資產組）時，PG寶石確實無法找到，因爲它位於生產組中。

我會建議在全局組中擁有pg gem並且可以允許資產組。
