Question

我是Kivy的新手。安装Kivy及其所有组件之后，我尝试运行名为Showcase的演示，并在cmd中收到以下错误消息：

[CRITICAL] [Window      ] Unable to find any valuable Window provider. Please enable debug logging (e.g. add -d if running from the command line, or change the log level in the config) and re-run your app to identify potential causes
