Unity iOS构建后自动执行Pod命令报错：Run命令未找到，如何解决？

错误原因 #

1. 无效的Run参数：你在pod命令的Arguments里添加了Run，但Pod没有这个子命令，这是报错的直接原因。
2. 命令执行对象错误：rm -rf ~/Library/Developer/Xcode/DerivedData是Shell命令，不能通过Pod进程执行，需要用bash这类Shell来运行。
3. 冗余命令：pod install和pod update无需连续执行，构建后场景下pod install通常足够满足需求。

        project.AddBuildProperty(target, "CLANG_ENABLE_MODULES", "YES");

#endif

额外优化点 #

• 新增RedirectStandardError捕获命令执行的错误信息，便于排查问题。
• 使用using语句管理Process对象，确保资源正确释放。
• 调用WaitForExit()等待每个命令执行完成后再进行下一个，避免并发问题。
