完成捆绑安装后,我推送到heroku,当它到达sqlite3安装时出现以下错误.

我的Gemfile看起来像这样：

source 'https://rubygems.org'

gem 'rails','3.2.2'

# Bundle edge Rails instead:
# gem 'rails',:git => 'git://github.com/rails/rails.git'

gem 'json'

group :development,:test do 
  gem 'sqlite3-ruby',:require => 'sqlite3'
  gem 'sqlite3','1.3.5'
end 

# 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' 

  gem 'uglifier','>= 1.0.3'
end

gem 'jquery-rails'

group :production do
  gem 'pg','0.12.2'
end

# 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 'ruby-debug'

看起来我有两个

Using sqlite3 (1.3.5)
Using sqlite3-ruby (1.3.3)

在我的系统上.不确定这是否是一个问题,但解释了为什么我在gemfile中排除了这两个问题.

环境信息：

$ruby -v 
ruby 1.8.7 (2012-02-08 patchlevel 358) [i386-cygwin] 

$rails -v 
Rails 3.2.2
