Mac环境Flutter构建CocoaPods与ffmpeg_kit_flutter版本兼容问题求助

错误原因分析 #

从日志可以明确看出，ffmpeg_kit_flutter/https 6.0.3需要更高的最低部署目标版本，当前项目的部署目标不满足该依赖要求，导致CocoaPods无法解析到兼容版本。

解决方案 #

方案1：升级项目最低部署目标（推荐） #

这是适配依赖要求最直接的解决方式：

• 打开Mac项目的Runner.xcworkspace
• 在Xcode中选中Runner目标，切换到General标签页
• 在Deployment Info区域将macOS Deployment Target升级到依赖要求的版本（ffmpeg_kit_flutter 6.x系列通常要求macOS 10.15及以上）
• 保存后，在终端执行以下命令重新安装依赖：

flutter clean
cd macos
pod deintegrate
pod install

方案2：在Podfile中强制指定兼容的ffmpeg_kit_flutter版本 #

如果需要固定特定版本的ffmpeg依赖，可以通过修改Podfile覆盖自动生成的版本配置：

1. 打开项目根目录下的macos/Podfile
2. 在flutter_install_all_ios_pods代码之前，添加版本锁定代码：

# 指定适配当前部署目标的ffmpeg_kit_flutter版本
pod 'ffmpeg_kit_flutter/https', '~> 5.1.0'

3. 修改后的Podfile核心部分示例：

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  # 新增版本锁定代码
  pod 'ffmpeg_kit_flutter/https', '~> 5.1.0'
  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
  target 'RunnerTests' do
    inherit! :search_paths
  end
end

4. 执行以下命令重新同步依赖：

flutter clean
cd macos
pod repo update
pod install
