最近将这个heroku应用程序更改为mysql，现在我正在使用资产管道获取此错误
这是heroku的完整输出，我按照heroku推荐的所有步骤来执行此操作，但没有任何效果。
我在我的application.rb
上设置了这个config.assets.initialize_on_precompile = false
我也通过heroku config将新的mysql连接字符串设置为DATABASE_URL。
这基本上是我在部署到heroku时遇到的错误，我几乎可以肯定这一定是非常简单的事情，但我还是没能弄明白。

Heroku使用PostgreSQL数据库，因此您需要在生产环境中使用'pg'gem。您可以在开发模式下使用MySql
在你的Gemfile中使用
更改'mysql2'gemgroup :development do
gem 'mysql2', '~> 0.3.15'
end
group :production do
gem 'pg', '0.15.1'
gem 'rails_12factor', '0.0.2'
end
现在运行 bundle install --without production 来安装宝石
