未能找到“Framework/App.framework/flutter_ assets”的资产路径

Question

我正试图在模拟器( iPhone 8)上运行我的颤音应用程序，但当应用程序午餐时，我得到的只是一个空白的白屏幕。就像这样：

​

​

终端输出是：

Running pod install...                                             40.0s

我正在使用稳定版本的颤振1.12.13+hotfix.9，这个问题只出现在ios大楼上。

我怎样才能解决这个问题？

Answer 1

我刚刚解决了这个问题。我刚刚遵循了建议https://github.com/flutter/flutter/issues/29974并添加了https://github.com/flutter/flutter/issues/29974嵌入来运行脚本运行脚本，在重新构建App.framework文件夹以构建目录之后，问题就消失了。希望这能帮到别人。

Answer 2

您可以按照https://flutter.dev/docs/development/ios-project-migration中的说明进行操作

特别是构建阶段：

/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed
/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" thin

您可以在这里看到更多信息：https://github.com/flutter/flutter/issues/52084#issuecomment-600768772

Answer 3

首先，您应该在android工作室终端中编写以下命令：

• rm -rf ios/Flutter/App.framework
• 然后在Xcode中选择，然后选择Runner
• 之后，从中间顶级选项中选择构建阶段
• 然后打开瘦二进制
• 将脚本移除

/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh“嵌入

/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh“thin

这对我有用，希望，也能为你工作:-)
