无法在 flutter 中调试桌面

Question

我正在尝试使用默认 Flutter 项目首次启动 Windows 应用程序，但它显示此错误，

Launching lib\main.dart on Windows in debug mode...
lib\main.dart:1
Can't load AOT data from {#project-path}\build\windows\runner\Debug\data\app.so; no such file.
Unable to start engine without AOT data.
Failed to create view controller.
Error waiting for a debug connection: The log reader stopped unexpectedly, or never started.
Error launching application on Windows.
Exited (sigterm)

这是我的 flutter doctor -v 结果：

这是我已经尝试过的

1. 复制粘贴 app.so 文件./build/windows 到 ./build/windows/runner/Debug/data 这是一个低效的解决方案，因为热重载不起作用。
2. 将 Visual Studio 降级到 2019 我尝试将 Visual Studio 降级到 2019，然后从根目录中删除 windows 文件夹，然后运行 ​​flutter clean 和 flutter create .。然后开始调试，发生了这个错误，

Launching lib\main.dart on Windows in debug mode...
lib\main.dart:1
Error waiting for a debug connection: The log reader stopped unexpectedly, or never started.
Error launching application on Windows.
Exited (sigterm)

所以我卸载了 Visual Studio 并安装了 2022 版本。

3. 也尝试了flutter clean没有效果。

对于这个错误我该怎么办？

Answer 1

这是 Visual Studio 2022 最新更新附带的 CMake 版本中的一个错误目前除了使用早期版本的 VS 之外没有好的解决方法，但您可以按照该问题进行更新。

Answer 2

当你降级到Visual Studio 2019时，你是否简单地删除了Visual Studio 2022？

我发现当我简单删除Visual Studio 2022时，我遇到了同样的错误。我成功地从 Visual Studio 2019 中卸载并重新安装了“使用 C++ 进行桌面开发”，然后安装了 flutter clean 和 flutter run -d windows。

Answer 3

我已经修复了这个 github 问题。flutter github 问题
