msys2 / mingw64：pip：此模块不支持VC 6.0

Question

我尝试在Windows 10（mingw64）中安装软件包并收到此错误：

        raise DistutilsPlatformError("VC %0.1f is not supported by this module" % VERSION)
    distutils.errors.DistutilsPlatformError: VC 6.0 is not supported by this module

我该怎么做才能解决这个问题？

我按照这些说明来设置我的开发环境：https://www.gtk.org/download/windows.php

更新

只是为了记录，我从gtk切换到qt（PySide2），现在我可以使用默认的Python for Windows。现在一切都变得容易了。

在MSYS2中，许多问题都是使用进入pacman存储库的MINGW包下游修补的。在这种情况下，您收到此错误的原因是您安装了setuptools pip，而不是使用pacman存储库安装。要解决此问题：

pip uninstall setuptools
pacman -S mingw-w64-x86_64-python-setuptools

或者如果您使用的是现代Python：

pip3 uninstall setuptools
pacman -S mingw-w64-x86_x64-python3-setuptools
