在哪里下载kivy 1.0.9？

Question

我一直在关注本教程：http://kivy.org/docs/tutorials/pong.html。在完成“添加简单图形”下的步骤后，我尝试运行该程序，但不是带有白线和两个零的黑屏，而是黑屏。我复制粘贴了代码并将文件放在同一目录中。在shell中它说它在pong_directory中找不到pong.kv，但我检查了两次，它就在那里。

Answer 1

您不需要（或想要！）kivy 1.0.9，它真的很旧 - 它只是最低要求。乒乓教程应该可以正常工作。

不清楚您的实际问题是什么 - 您正在运行教程的哪一部分（您可以粘贴代码）？第一个可运行示例应该给出一个黑色窗口（那里没有其他代码），而第二个使用在您的日志中找不到的 pong.kv 文件。
