如何判断不同的 rails 版本应该用哪个版本的 gem

我用的 rails 版本是 6.0.5.1，gem 引用了 gem 'database_cleaner', '~> 1.5.3'，gem 'rspec-rails', '~> 5.0.0'，用 rspec 命令进行单元测试出现一个错误

DEPRECATION WARNING: Initialization autoloaded the constants ActionText::ContentHelper and ActionText::TagHelper.

Being able to do this is deprecated. Autoloading during initialization is going
to be an error condition in future versions of Rails.

Reloading does not reboot the application, and therefore code executed during
initialization does not run again. So, if you reload ActionText::ContentHelper, for example,
the expected changes won't be reflected in that stale Module object.

These autoloaded constants have been unloaded.

Please, check the "Autoloading and Reloading Constants" guide for solutions.

查了一下，好像是 database_cleaner 的版本不对。那么我如何判断某个版本的 rails 该用哪个版本的 gem 呢？

关于自动加载：require_dependencies 的问题

我有一个 rails 应用 api，里面的 model 中的某个.rb 文件中用到了一个方法 DatabaseName：：TableName.find_sth，find_sth 这个方法并没有定义在 api 这个包里，而是定义在另一个包——common 里，但是 api 中并没有 require/include 这个包。api 中有两处与 common 包相关的地方，一个是 gem“common”，但经过测试，并不是 gem 了这个包 api 就能认识 common 中的方法 (以及数据库名或表名)；另一个是在 api\config\initializers\中的一个文件里有一句——Common：：Projects.require_dependencies(:api) 我感觉这里是能说明为什么 api 能认识 common 中的方法，但是我还是不懂是怎么实现的，而且 require_dependencies 这个方法也定义在 common 中，这不是一个官方的方法吗？Common：：Projects.require_dependencies(:api) 看起来也是直接用了 Common 这个包...... 求大神解惑
