我目前正在为React Native开发设置一台新的笔记本电脑（Intel MacBook Pro），并使用brew安装了ruby 3.1.2和Cocoapods。但是，当在我的项目上运行pod install时，我得到了这个错误：

/usr/local/lib/ruby/gems/3.1.0/gems/activesupport-7.0.0.rc3/lib/active_support/xml_mini.rb:184:in `current_thread_backend': uninitialized constant ActiveSupport::XmlMini::IsolatedExecutionState (NameError)

    IsolatedExecutionState[:xml_mini_backend]

我在网上能找到的只有几个月前的这个未回答的问题：pod init got uninitialized constant ActiveSupport::XmlMini::IsolatedExecutionState (NameError)
有什么想法吗？我的Ruby知识是零！
