Flutter error: No CMAKE_CXX_COMPILER could be found

Question

我是 Flutter 新手。当我想在 Windows 上运行我的 Flutter 应用程序时，我收到此错误：

Launching lib\main.dart on Windows in debug mode...
CMake Error at CMakeLists.txt:2 (project):
  No CMAKE_CXX_COMPILER could be found.



Building Windows application...
Exception: Unable to generate build files

这是 flutter doctor -v 的输出：

一切正常。问题出在哪里？

我阅读了之前的所有答案，但对我没有任何帮助。

Answer 1

也许转到 Android Studio，菜单文件 → 设置 → 外观和行为 → 系统设置 → SDK 工具.

检查 CMake 字段是否被选中。

另一个：

检查开发者选项是否被选中（在Windows）* 设置 → 更新和安全 → 对于开发人员 → 开发人员模式（如果关闭，请打开）。

Answer 2

解决这个问题有两种可能：

尝试重新安装 Windows SDK 并再次运行
安装 sudo apt-get install build-essential

Answer 3

我解决了这个问题，但我不知道具体的解决方案是什么。

我认为解决方案是从 Visual Studio 中卸载整个“使用 C++ 进行桌面开发”并重新安装。

然后在我的Flutter工程目录下：

flutter clean 和 flutter create .
