ruby-on-rails - 删除了 sqlite gem 但 Heroku 仍然检测到 sqlite gem 并且失败

Question

我正在尝试将 Rails 应用程序部署到 heroku，但出现以下错误。

Detected sqlite3 gem which is not supported on Heroku

我已经从我的项目中删除了对 sqlite3 的任何引用并将其转换为使用“pg”，更新了 Gemfile.lock 并提交了它，但错误仍然存​​在。

这是我的 gemfile

source 'https://rubygems.org'

group :test, :development do
  #testing
  gem 'rspec-rails', '~ 3.0'
  gem 'factory_girl_rails', '~ 4.0'
  gem 'guard-rspec', require: false
  gem 'faker'
  gem 'database_cleaner'
end

# Use postgres as the database for Active Record
gem 'pg'
gem 'rails_12factor'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.4'

# Use SCSS for stylesheets
gem 'sass-rails', '~ 4.0.3'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '= 1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~ 4.0.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer',  platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~ 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~ 0.4.0',          group: :doc

# Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
#gem 'spring',        group: :development

# Use ActiveModel has_secure_password
#gem 'bcrypt', '~ 3.1.7'

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

# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development

# Use debugger
# gem 'debugger', group: [:development, :test]

ruby '2.0.0'

这是我的database.yml

development:
  adapter: postgresql
  encoding: SQL_ASCII
  database: rock_development
  pool: 5


test:
  adapter: postgresql
  encoding: SQL_ASCII
  database: rock_test
  pool: 5

这是我的 heroku 日志

问题解决了。这实际上是我如何使用 git 的问题。我创建了一个新分支来进行从 sqlite 到 ppsql 的更改，并且我试图从该分支推送到 heroku。事实证明，当您说“git push heroku master”时，它不是从您当前的分支推送，而是从 master 分支推送。在我的例子中，它仍然被配置为使用 sqlite。要解决此问题，请在推送到 heroku 之前先与您的 master 分支合并。
