如何从Ruby脚本初始化Rails 5.1环境进行发条工作

Question

我需要从任意脚本中初始化Rails，以便可以使用Clockwork访问一些ActiveRecord对象

更新：仅当同时require 'clockwork'和require_relative './config/environment'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'似乎两次包含了openssl或类似的东西，导致了一堆警告，最后是一个错误（如下）

我在MacOS High Sierra上使用rbenv运行rails 5.1，ruby 4.2.1。

不知道这是否是初始化rails的正确方法（似乎正在搜索谷歌），或者这仅仅是我的设置问题。 请帮忙！

Answer 1

问题是我有两个版本的openssl gem试图同时加载。

做一个gem list显示： openssl (2.0.5, default: 2.0.3)

恢复为默认版本可解决此问题：

gem uninstall openssl -v 2.0.5
gem install openssl -v 2.0.3
