编译 Qt 6.2.1: "qplatformdefs.h": 没有那个文件或目录
Compiling Qt 6.2.1: "qplatformdefs.h": No such file or directory
所以我有一个问题，当我尝试安装 Qt 6.2.1 时 Qt 安装程序失败了，我想我必须自己编译源代码才能让它工作。我的 configure.bat 命令行是：
configure -debug-and-release -opensource -confirm-license -platform win32-msvc2019 -nomake examples -nomake tests -prefix E:\qt-stuff.2.1-build\
（此命令和所有下一个命令在 VS 2019 的 x86 本机工具命令提示符中是 运行）
它在控制台中发送了很多垃圾邮件，最后成功了，告诉我：
Qt is now configured for building. Just run 'cmake --build . --parallel'
Once everything is built, you must run 'ninja install'
Qt will be installed into 'E:/qt-stuff/6.2.1-build'
To configure and build other Qt modules, you can use the following convenience script:
E:/qt-stuff/6.2.1-build/bin/qt-configure-module.bat
If reconfiguration fails for some reason, try to remove 'CMakeCache.txt' from the build directory
-- Configuring done
-- Generating done
-- Build files have been written to: E:/qt-stuff/qt-everywhere-src-6.2.1
但是当我 运行 cmake --build . --parallel 4 时，它会向一些文件发送大量路径，最后失败，说 ninja: build stopped: subcommand failed.
我能找到的实际错误是：

我以前编译过Qt，有时能用，有时不能用。但是现在无论我尝试什么都无法构建它。
如有任何帮助，我们将不胜感激
问题出在 platform 参数上。请将 win32-msvc2019 替换为 win32-msvc.
问题编译器找不到该文件，因为它位于 qtbase\mkspecs\win32-msvc 文件夹中，但在您的情况下，它正在查找 qtbase\mkspecs\win32-msvc2019.
我查看了配置脚本的帮助，没有关于可能值的信息。以及在 Qt 文档中。似乎检查正确值的唯一可能方法是列出 mkspecs 文件夹
