问题

CocoaPods执行更新指令pod --version的时候遇到如下错误

/usr/local/lib/ruby/gems/3.2.0/gems/activesupport-7.1.1/lib/active_support/core_ext/array/conversions.rb:108:in `<class:Array>': undefined method `deprecator' for ActiveSupport:Module (NoMethodError)

  deprecate to_default_s: :to_s, deprecator: ActiveSupport.deprecator

解决

从错误上看Cocoapods 使用activesupport 中方法找不到对应的方法。
解决方案要先下载个老版本的activesupport，替换掉7.1.1。

1、下载旧版本activesupport

sudo gem install activesupport -v 7.0.8

2、查看是否下载完成

gem list
