Python 如何在VisualStudio2019中解决OpenCV问题

我对OpenCV（cv2）有以下问题。我不知道怎么解决它。 我使用的是VS2019，最新的OpenCV和最新的Python环境

错误代码： OpenCV（4.1.1）C:\projects\OpenCV python\OpenCV\modules\highgui\src\window.cpp:627:错误：（-2:未指定的错误）未实现该函数。使用Windows、GTK+2.x或Cocoa支持重建库。如果您在Ubuntu或Debian上，请安装libgtk2.0-dev和pkg-config，然后在函数“cvShowImage”中重新运行cmake或配置脚本
