Heroku：推送被拒絕，未能編譯Ruby應用程序

Question

我被困一個星期試圖弄清楚這一點。我目前一直在關注在線講座，但是我完全遵循了一切，講師並沒有任何幫助。每當我嘗試推送到heroku我收到以下內容：

初始化存儲庫，完成。計數對象：85，完成。 增量壓縮使用多達2個線程。 壓縮對象：100％（76/76），完成。 寫作對象：100％（85/85），27.36 KiB，完成。 共有85（三角洲6），再用0（0增量）

我試圖重建寶石文件，刪除Gemfile.lock的運行包安裝，下面從前面的問題的解決方案，但我仍然得到這個錯誤。

這裏是我當前的Gemfile：

source 'https://rubygems.org' 

gem 'rails', '3.2.13' 

# 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' 

    # 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', '~> 3.0.0' 

# 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' 

group :development do 
    gem 'sqlite3' 
    gem 'rspec-rails', '2.6.1', :require => 'rspec-rails' 
    gem 'faker', '0.3.1' 
end 

group :test do 
    gem 'sqlite3' 
    gem 'rspec-rails', '2.6.1', :require => 'rpec-rails' 
    gem 'webrat', '0.7.1' 
    gem 'factory_girl_rails', '1.0' 
    gem 'turn', :require => false 
end 

group :production do 
    gem 'pg' 
end 

任何幫助？

Answer 1

我推薦幾件事情：

1）按照說明here到處理部署在Windows上生成的Ruby項目時出現的Gemfile問題。

2）執行以下步驟，您的Gemfile

group :test, :production do 
    gem 'pg' 
end 

group :development do 
    gem 'sqlite3' 
end 

這會從您的生產部署擺脫sqlite3。使用它進行單元和集成測試，但使用PostgreSQL進行驗收/功能測試，因爲這是Heroku所選擇的RDBMS。此外，每個參考寶石只有一次。

3）在Heroku的部署環境中設置Hobby Dev version of the PostgreSQL add-on。

Answer 2

You can't use SQLite on Heroku，你必須使用PostgreSQL。

您可以將它設置爲在Heroku上使用PostgreSQL，但在開發中使用SQLite時，在開發和生產環境中使用相同的數據庫是一種很好的做法。

請注意，您多次列出gem 'sqlite3'，包括開發組之外的一個。這會導致Heroku嘗試安裝它。

我的建議是完全刪除sqlite gem並將所有切換到PostgreSQL。

Answer 3

卸下頂部gem sqlite3，並在您的Gemfile的頂部添加ruby '2.0.0'

也是該集團生產下添加gem 'rails_12factor'
