Ruby on rails rails控制台与使用Mechanize包装器的irb中的统一化常量错误

基本层面的第一个问题——Ruby中未初始化常量错误的含义是什么？我来自objective-c背景，如果这有助于提供一些上下文的话

其次，我正在rails中运行一个rake任务，该任务抛出了前面提到的错误。具体来说，错误发生在我使用“tor privoxy”gem时，这是一个允许通过tor代理自动浏览的机械化包装器

我正在使用github上提供的以下示例代码：

---

另一方面，如果我在irb中运行相同的代码，它不会抛出单位化常量错误。我已确保我的gemfile中包含“tor privoxy”，并运行了“bundle install”命令。

如果您想在mac上使用ruby，我建议您使用rvm或rbenv等工具来管理ruby的安装

您正在经历的错误似乎已经为人所知。看看这个github问题：

我已经安装了包含此更新的NetHTTPPersistence2.7。Mechanize需要此宝石@2.5或更高。这不应该缓解这个问题吗？请删除所有旧版本以确保安全。

agent ||= TorPrivoxy::Agent.new '127.0.0.1', '', {8118 => 9050} do |agent|
    sleep 10
    puts "New IP is #{agent.ip}"
    page = agent.get('https://www.example.com/')
end
>> New IP is 72.141.125.115
>> NameError: uninitialized constant Net::HTTP::Persistent::SSLReuse::HTTPResponse
