       FAILED: http://devcenter.heroku.com/articles/bundler  !     Heroku push rejected, failed to install gems via Bundler

所以，当然看起来像 this我把gemfile里面的db改成了pg+bundle install，bundler之后就没有错误了。但我又看到了。这是我的 gemfile

source 'http://rubygems.org'

gem 'rails', '3.1.1'

# 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',   '~> 3.1.4'
  gem 'coffee-rails', '~> 3.1.1'
  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

group :production, :staging do
  #gem "mysql2"
  #gem 'sqlite3-ruby', :require => 'sqlite3'
  gem "pg"
end

group :development, :test do
  gem "pg"
  #gem "sqlite3-ruby", :require => "sqlite3"
end

#gem 'ruby-xslt'

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'ruby-debug19', :require => 'ruby-debug'

group :test do
  # Pretty printed test output
  gem 'turn', :require => false
end

为什么？

Answer 1

你可以更改为 pg 并添加以下行吗

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

然后执行，如果遇到任何问题请告诉我？
