Question

我已尽可能多地查看现有答案，但我无法弄清楚为什么heroku仍在尝试安装sqlite3。下面是我的gemfile，我甚至没有sqlite3，因为我在开发，测试和生产中使用mysql。我错过了什么？我也没有看到任何依赖？

我在尝试推送时收到错误Detected sqlite3 gem which is not supported on Heroku。

的Gemfile

source 'https://rubygems.org'

gem 'thin'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.1'

#mysql
gem 'mysql2'


# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.0'

# 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

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder

#backup db with yaml_db
gem 'yaml_db', github: 'jetthoughts/yaml_db', ref: 'fb4b6bd7e12de3cffa93e0a298a1e5253d7e92ba'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end

如评论中所述，您可能无法重建Gemfile.lock。执行此操作的方法是在开发系统上运行bundle install（重建Gemfile.lock），然后再次推送到Heroku：

$ bundle install
$ git add .
$ git commit -a -m "SQLite3"
$ git push heroku master

Rails 4 - 删除了sqlite3 gem - “检测到Heroku不支持的sqlite3 gem”
