新的Flutter应用程序构建失败，导致模拟器失败，权限被拒绝

Question

当我尝试def input_handler(data, context): d = data.read().decode('utf-8') body = json.loads(d) s3path = body['s3_path'] s3 = S3FileSystem() df = np.load(s3.open(s3path)) return df 一个新创建的flutter应用程序时，构建失败，并出现以下错误。该计算机是在一年前用于Flutter开发的，我怀疑某个地方的某些不规则配置会导致此错误。我已经为此苦苦挣扎了几天，任何帮助将不胜感激。

2. flutter run
3. flutter create my_app

终端输出：

cd my_app

我已经尝试过：

• 卸载并重新安装Xcode
• 卸载并重新安装Flutter
• 从Xcode运行
• 删除pod / podfile并重新安装
• 重新启动计算机
• flutter run
• 创建新应用
• 检查是否符合Flutter所有“ Get started”说明
• 从Xcode运行
• 将工作区切换到旧版构建系统
• Locking & unlocking login in Keychain Access
• 使用Finder授予对项目文件夹和所有附带项目的读/写权限，并在文件上运行app/Frameworks/App.framework/App: signed bundle with Mach-O universal (x86_64 arm64) [io.flutter.flutter.app] /Users/user/Desktop/projects/myApp/build/ios/Debug-iphonesimulator/Runner. app/Frameworks/Flutter.framework/Flutter: replacing existing signature /Users/user/Desktop/projects/myApp/build/ios/Debug-iphonesimulator/Runner. app/Frameworks/Flutter.framework/Flutter: Permission denied Command PhaseScriptExecution failed with a nonzero exit code note: Using new build system note: Building targets in parallel note: Planning build note: Constructing build description Could not build the application for the simulator.

flutter clean输出：

chmod +x

更新：I have opened an issue in the Flutter Github repo。

基于this问题，这似乎与xcode_backend.sh文件有关，使得某些Flutter文件为只读，请检查问题和this问题，可能有助于您解决问题，祝你好运。

Answer 2

我终于能够解决此问题，并通过执行以下步骤在iOS模拟器上运行Flutter演示应用程序：

1. flutter version v1.11.0（降级为Flutter的早期版本）
2. flutter channel stable
3. flutter upgrade
4. flutter doctor
5. flutter create test_app
6. cd test_app
7. flutter run
