【问题描述】：
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：仅当 require 'clockwork' 和 require_relative './config/environment' 都需要时才会出现此问题。
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 两次或什么，导致一大堆警告，最后一个错误（下）
我在 MacOS High Sierra 上使用 rbenv 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！
