ruby-on-rails - Heroku 部署问题.. 仍然

Question

昨天我问了一个关于插入 Heroku 的问题。它不工作，然后突然开始工作。我什么都没改变。现在在一个新的应用程序上，我遇到了完全相同的问题。我决定包含我的整个 Gemfile，希望我可以继续没有这种令人难以置信的挫败感

source 'https://rubygems.org'

gem 'rails', '3.2.11'

group :production, :staging do
  gem "pg"
end

group :development, :test do
  gem "sqlite3-ruby", "~> 1.3.0", :require => "sqlite3"
end

group :development do
  gem 'rspec-rails', '2.3'
end

group :test do
  gem 'rspec-rails', '2.3'
end


# 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'

更新 gem 文件后，我运行:

$bundle install
$git add Gemfile
$git add Gemfile.lock
$git git commit -m "message"
$git push heroku master

我仍然收到此错误

An error occurred while installing sqlite3 (1.3.7), and Bundler cannot continue.
       Make sure that `gem install sqlite3 -v '1.3.7'` succeeds before bundling.

 !     Failed to install gems via Bundler.

Answer 1

安装 sqlite3 似乎有问题gem，在您的 Gemfile 中指定要在所有环境中安装，即使 Heroku 不会使用它。

尝试移动gem 'sqlite3'到开发组，这样您的生产环境就不会尝试安装它。
