mysql - Heroku 部署失败 MySQL rake 中止同一文件

Question

最近将此heroku应用程序更改为mysql，现在我在 Assets 管道中遇到此错误

这是heroku 的完整输出，我按照heroku 推荐的所有步骤执行此操作，但没有任何效果。

我的 application.rb 上有这个设置

config.assets.initialize_on_precompile = false

我还通过heroku配置使用新的mysql连接字符串设置了DATABASE_URL。

这基本上是我在部署到heroku时遇到的错误，我几乎确定这一定是非常简单的事情，但我只是无法弄清楚。

Compiled application.css  (2781ms)  (pid 1424)
       rake aborted!
       same file: /tmp/build_0aa9e509-f693-452f-885c-d32e2be60991/public/assets/+ and /tmp/build_0aa9e509-f693-452f-885c-d32e2be60991/public/assets/+

任何帮助将不胜感激。

Answer 1

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 Gemfile 中将 'mysql2' gem 更改为

group :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gems
