解决方法 #

1. 升级CocoaPods到兼容版本 #

CocoaPods 1.11.3与Ruby 3.2.x存在兼容性问题，升级到1.12.0及以上版本即可修复：

sudo gem install cocoapods

若需指定版本：

sudo gem install cocoapods -v 1.12.1

2. 修复插件的xcconfig配置 #

错误中的PICKER_*配置来自文件选择类插件，插件的xcconfig文件错误地将配置项以嵌套数组形式传递，导致CocoaPods无法解析：

• 找到项目依赖的相关插件，进入其ios目录
• 打开.xcconfig文件，将类似[["PICKER_MEDIA=1"], ["PICKER_AUDIO=1"]]的格式改为单行键值对：

  PICKER_MEDIA=1
  PICKER_AUDIO=1
  PICKER_DOCUMENT=1
  

3. 降级Ruby版本 #

若暂时不想升级CocoaPods，可使用rbenv或rvm将Ruby版本降到3.1.x及以下：

# rbenv示例
rbenv install 3.1.4
rbenv local 3.1.4
