在heroku部署之后迁移时出现sqlite错误

Question

所以我将我的应用程序部署到Heroku并安装了gem＆＃39; pg＆＃39;并删除了sqlite。 我在本地或Heroku上迁移时出现此错误

Gem::LoadError: Specified 'sqlite3' for database adapter, but the gem is not loaded. Add `gem 'sqlite3'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).

我该如何解决这个问题？感谢

Answer 1

在开发中添加"sqlite3"，在"pg"

中添加production

group :development, :test do
  gem 'sqlite3'
end

group :production do
  gem 'pg'
end
