Question

我正在尝试使自己适应Kivy框架，我也是Python的新手，所以我真的无法解决这个问题。但是基本上我正在尝试这些示例，而Kivy目录之一却无法正常工作，我正在终端上接受它。我在使用Python3.7的macOS 10.14.4上。

Answer 1

尝试从gstreamer中删除kivy/lib目录。

将目录更改为Kivy文件夹，例如cd usr/local/lib/python3.7/site-packages/kivy/lib
删除gstreamer，rm -R gstreamer
重新运行应用

加载纹理../../widgets/cityCC0.mpg时出错
