【中文标题】为啥在使用 Flutter 模块构建 iOS 原生应用时修复“Frameworks/Flutter.framework: Permission denied”？【英文标题】：Why to fix "Frameworks/Flutter.framework: Permission denied" while building iOS native app with flutter module?为什么在使用 Flutter 模块构建 iOS 原生应用时修复“Frameworks/Flutter.framework: Permission denied”？ 【发布时间】：2020-01-25 06:18:43 【问题描述】：我创建了一个 ios 单视图应用程序 (hostapp) 并将其转换为 pod 工作区。运行良好。
然后创建了flutter模块（clientapp），提供给iOS团队。运行良好，独立。
关闭了 hostapp 和 clientapp 的 Bitcode，因为它会导致其他问题。
现在通过 podfile 将 clientapp 添加到 hostapp，没有内部代码更改。在 hostapp 中安装 pod 后，我尝试构建它。然后它抛出/Users/iVoIP/Library/Developer/Xcode/DerivedData/hostapp-czxdwjjefjvrnhhdvbmaqeczngbh/Build/Products/Debug-iphonesimulator/hostapp.app/Frameworks/Flutter.framework: Permission denied
/Users/iVoIP/Library/Developer/Xcode/DerivedData/hostapp-czxdwjjefjvrnhhdvbmaqeczngbh/Build/Products/Debug-iphonesimulator/hostapp.app/Frameworks/ chmod 更改为 777

这样就可以了！！

如你所说改变了，但还是一样。我需要重新创建项目或其他任何东西吗？ 更改该行后，删除 derivedData 并清理 xcode 项目...检查一次！如果这不起作用，请发布 xcode_backend.sh 文件内容和颤振医生命令输出！ 感谢您的帮助。转移到 master 分支解决了这个问题。 git issue 谢谢！！救了我的一天！就我而言，这条线已经存在，但它仍然无法与 flutter_blue 一起使用。我已将其更改为 xxx 而不是 a-w 并且有效以上是关于为啥在使用 Flutter 模块构建 iOS 原生应用时修复“Frameworks/Flutter.framework: Permission denied”？的主要内容，如果未能解决你的问题，请参考以下文章
