简报：上周我一直在尝试将我的博客部署到 heroku，但没有成功。我已经联系了 Heroku 支持，他们几乎告诉我在 stackoverflow 上发布日志。所以我在这里。

看起来好像有某种数据库配置错误，但我不得不指出它。无论如何，这是代码库：www.github.com/apane/blogit_blog。

Heroku 日志如下。

Gemfile 提供了很好的衡量标准：

source 'https://rubygems.org'

gem 'rails', '3.2.13'

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

gem 'blogit', '0.8.0'

gem "will_paginate", "~> 3.0.4"

gem 'devise'

# Gems used only for assets and not required
# in production environments by default.

group :production do
  gem 'pg'
  gem "unicorn", "~> 4.6.2"

end
group :development, :test do
  gem 'pg'
  gem "unicorn", "~> 4.6.2"

end

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

我会检查你的database.yml文件，因为目前你已经为 sqlite 设置了它，而在你的 gemfile 中你已经确定 postgresql 是你的数据库。还有一个事实是您的生产部分有一个额外的缩进。

development:
  adapter: postgresql
  encoding: unicode
  database: blog_dev
  pool: 5
  host: localhost
  username: u

test:
  adapter: postgresql
  encoding: unicode
  database: blog_test
  pool: 5
  host: localhost
  username: u

production:
  adapter: postgresql
  encoding: unicode
  database: blog_production
  pool: 5
  username: u

请注意，您还应该创建一个blog_dev和blog_test数据库。我也会替换

group :production do
  gem 'pg'
  gem "unicorn", "~> 4.6.2"
end

group :development, :test do
  gem 'pg'
  gem "unicorn", "~> 4.6.2"
end

有了这个

gem 'pg'
gem "unicorn", "~> 4.6.2"

在你的gemfile.

看起来您还没有创建数据库或者您没有打开 Postgresql。不确定您是否已为 postgresql 设置，但如果您有 Mac OS XI，则发现Postgres应用程序就足够了。

看起来，在您的 database.yml 文件中，第 22 行有一个缩进不匹配，这个词production应该与其他标题平行development，test.

这是因为 YAML 文件对空间敏感；在此处阅读有关 YAML 的更多信息。
