无法在 Iphone 设备上启动我的 flutter 应用程序以在 Mac M1 上进行调试

Question

当我尝试启动应用程序时，出现以下错误。

Xcode build done.                                           18.7s

Failed to build iOS app

Could not build the precompiled application for the device.

Error output from Xcode build:


↳


    ** BUILD FAILED **

Xcode's output:

我尝试过：

cd ios
sudo arch -x86_64 gem install ffi
arch -x86_64 pod repo update
arch -x86_64 pod install

根本没用。

> flutter --version
     Flutter 3.22.2 • channel stable • https://github.com/flutter/flutter.git
     Framework • revision 761747bfc5 (5 days ago) • 2024-06-05 22:15:13 +0200
     Engine • revision edd8546116
     Tools • Dart 3.4.3 • DevTools 2.34.3

> pod --version
     1.15.2

如果我运行

flutter doctor -v

，它会说

No issues found

。

我花了几个小时但没有成功。谁可能遇到过这个问题并解决了它..？

这似乎是一个 Flutter 问题，由于某种原因，他们几个月都无法解决。

这个帖子正在解释这个问题： https://github.com/flutter/flutter/issues/140845

问题似乎是无法找到/识别 FLUTTER_BUILD_DIR 作为环境变量。更新配置中的调试、发布和配置文件信息解决了问题，如上面链接中给出的 GitHub 问题中所述。
