因此,我正在尝试将在 SQLite3 上本地运行良好的应用程序更改为 Postgresql,以便可以将其部署到 Heroku。我查看了各种帖子和教程,并对我的 Gem 文件和 database.yml 文件进行了调整,但是当我尝试 rake:db migrate 时,我收到错误消息:“请安装 postgresql 适配器。” 我知道大多数用户在他们的 gemfile 中不包含 gem 'pg' 时都会遇到这种情况,但我确实包含了它。
这是我收到的完整错误消息:http: //dpaste.com/hold/972379/
你能帮忙吗?我真的看了几十个帖子,并尝试了每一个配置。
我的 procfile 看起来像这样:
web: bundle exec thin start -p $PORT
我的 database.yml 看起来像这样:
development:
adapter: postgresql
encoding: utf8
database: project_development
pool: 5
username:
password:
test: &TEST
adapter: postgresql
encoding: utf8
database: project_test
pool: 5
username:
password:
production:
adapter: postgresql
encoding: utf8
database: project_production
pool: 5
username:
password:
我的 gemfile 看起来像这样:
source 'https://rubygems.org'
gem 'rails', '3.2.11'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'thin'
group :production do
gem 'pg'
end
group :development, :test do
gem 'sqlite3'
end
# Gems used only for assets and not required
# in production environments by default.
宝石'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'
注意:当我运行 bundle install 时,没有出现“使用 pg”,但我认为这是因为它不在生产中......仅供参考,以防万一它很重要
编辑: gem pg 在使用 heroku 生产时似乎运行良好。不知道发生了什么,因为一旦部署,它就不起作用了。这是我的heroku日志(我已经取出了我的电子邮件):
