如何解决Flutter iOS中“Command PhaseScriptExecution非零退出码”错误

我在这个问题上耗了快一周，至今没解决。以下是报错信息：

Could not build the precompiled application for the device.

Error launching application on iPhone.

我已经试过的解决方法：

• 刷新Flutter和Pod：执行rm Podfile.lock、flutter clean、flutter pub get、pod repo update、pod install；
• 清理Pod缓存后重新执行上述操作；
• 重装Xcode、Flutter、Android Studio；
• 勾选/取消勾选For install builds only和/或Based on dependency analysis选项；
• 参考多个Stack Overflow相关解决方案；
• 使用pngcheck检查所有PNG文件；
• 更新：更换全新电脑并重装环境，问题依旧；
• 重新创建Flutter应用。

所有尝试都没用。我的flutter doctor -v结果如下：
