我在编译引擎时遇到问题。
我按照这个步骤来编译引擎。
并尝试使用以下命令构建 iOS 模拟器：
sudo ./flutter/tools/gn --ios --simulator --unoptimized && sudo ./flutter/tools/gn --unoptimized && sudo ninja -C out/ios_debug_sim_unopt && sudo ninja -C out/host_debug_unopt
它编译得很好，但是使用以下命令构建的 android arm64 存在问题：
sudo ./flutter/tools/gn --android --unoptimized --android-cpu=arm64 && sudo ./flutter/tools/gn --unoptimized && sudo ninja -C out/android_debug_unopt_arm64 && sudo ninja -C out/host_debug_unopt
这是错误的最后回溯。

谁能建议我该怎么做？
