我需要从任意脚本初始化 rails，以便我可以使用Clockwork访问一些 ActiveRecord 对象
更新：该问题仅在require 'clockwork'两者require_relative './config/environment'都需要时发生。
他们建议像这样初始化它：
# rails-root-directory/my-file.rb
require 'clockwork'
require_relative './config/boot'
require_relative './config/environment'
可悲的是require_relative './config/environment'似乎包含openssl两次或其他内容，导致一大堆警告，最后出现错误（下）
我rbenv在 MacOS High Sierra 上运行 rails 5.1, ruby 4.2.1。
不确定这是否是初始化 rails 的正确方法（谷歌搜索似乎是这样），或者这只是我的设置问题。请帮忙！
