无法在 Python 中安装 Kivy

Question

我用python -m pip install kivy和python -m pip install kivy[full] kivy-examples安装了kivy，我尝试了数百种不同的安装方法，我试图用--force-reinstall作为管理员执行，但如果我写import kivy.app，这是输出：

但是，如果我只是执行import kivy，它会起作用。我该怎么办？在Python 3.9中，它是有效的。

Answer 1

输出显示kivy使用的是python 3.10版本，对于该版本，kivy仍处于开发状态。

因此，如果你在更改python版本时没有问题，你可以使用3.8.10版本，这就是我目前在kivy中使用的版本。

那么只需简单的pip install kivy和导入import kivy.app就可以像集成一样工作
