如何从发条的 ruby 脚本初始化 rails 5.1 环境
How to initialize rails 5.1 environment from ruby script for clockwork
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。
他们建议这样初始化：
# rails-root-directory/my-file.rb
require 'clockwork'
require_relative './config/boot'
require_relative './config/environment'
遗憾的是 require_relative './config/environment' 似乎包含了 openssl 两次左右，导致了一大堆警告，最后是一个错误（下图）
我是 运行 rails 5.1，ruby 4.2.1 在 MacOS High Sierra 上使用 rbenv。
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说的）或者这是否只是我的设置问题。请帮忙！

恢复到默认版本解决了问题：
gem uninstall openssl -v 2.0.5
gem install openssl -v 2.0.3

问题是我试图同时加载 openssl gem 的两个版本。
执行 gem list 显示：openssl (2.0.5, default: 2.0.3)
恢复到默认版本解决了问题：
gem uninstall openssl -v 2.0.5
gem install openssl -v 2.0.3
