Flutter IOS 构建：PhaseScriptExecution Thin\ 二进制构建命令失败

Question

我有一个 flutter 应用程序，正在移植到 ios。运行

flutter build ios -v

后，进程成功设置、安装依赖项并编译，但在构建阶段出现问题。

我尝试查看生成的

/var/folders/51/2ypxj09x2tq8m09320t8ghlm0000gn/T/flutter_tools.pEfCUq/flutter_ios_build_temp_dirRNfKNo/temporary_xcresult_bundle

文件，但

flutter_tools.pEfCUq

文件夹是空的。

寻找有关如何最好地调试此问题的一些见解。我应该在哪里寻找一些关于这里实际出了问题的见解？

Answer 1

尝试将 flutter 清理干净 我还建议重新安装 pods

sh脚本：

flutter clean
cd ios/
pod deintegrate
pod cache clean --all
rm -rf Pods
rm Podfile.lock
cd ..
flutter pub get
cd ios
pod install --repo-update
cd ..
