当我尝试在模拟器上运行 flutter 应用程序时，Xcode 出现问题。
构建进行 build succeed但随后出现一个弹出窗口，显示 Application launch for 'com.<My-app>' did not return a valid pid nor a launch error. No such process .
在此错误之前，我遇到了另一个错误 Flutter version unknown我用这个命令 xcode-select --install 解决了它.
这些是错误详细信息:

这个问题可能也与我之前遇到的错误有关(Flutter 版本未知)，但这是一个与 git 相关的问题。
最佳答案
就我而言，即使我没有在 Rosetta 下运行它，我也必须安装它。为此，请运行此脚本:
softwareupdate --install-rosetta
如果您想跳过许可协议(protocol)，请执行以下操作:
/usr/sbin/softwareupdate --install-rosetta --agree-to-license
关于ios - 构建成功后，应用程序启动没有返回有效的对，也没有在 Xcode 上返回启动错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/71435412/
