为数据库适配器指定了“sqlite3”，但运行 searchkick reindex 时未加载 gem？

Question

首先我根据环境分离了数据库

group :production do 
  gem 'pg'
end


group :development, :test do
  gem 'byebug'
  gem 'sqlite3'
  gem 'rspec-rails'
end

添加几条记录后。我在生产环境中运行了以下重新索引命令。

bundle exec rake searchkick:reindex CLASS=Book

但它给出了以下错误

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

Caused by:

尽管 pg 已设置为生产环境，但我感谢任何关于它为何搜索 sql 的帮助？

更新：

好的，我通过在 Rails 控制台生产中执行 Book.reindex 解决了这个问题，但我仍然想知道为什么

bundle exec rake searchkick:reindex CLASS=Book

因上述错误而失败？它在一开始就起作用了。在进行了一些升级（例如添加 aws-sdk）之后，它开始显示错误。 aws-sdk 会破坏它吗？

Answer 1

您可以尝试在生产组添加gem 'rails_12factor'

宝石文件

 group :production do 
    gem 'pg'
    gem 'rails_12factor'
 end

然后

bundle install
bundle update 

然后推送到生产环境并测试它

希望能帮到你
