我正在关注Kivy 的教程,但无法从 .kv 文件正确加载属性。出于某种原因,我有时可以通过 a 提取 .kv 文件for kv in listdir(kv_path): Builder.load_file(kv_path+kv),但我不能通过简单地将 kv 文件放在同一个根目录中并让它“自行导入”来做到这一点?例如,当使用文件时:main.pyfrom kivy.app import App from kivy.uix.label import Label from kivy.uix.widget import Widget class Widgets(Widget): passclass SimpleKivy3(App): def build(self): return Widgets()if __name__ == "__main__": SimpleKivy3().run()SimpleKivy3.kv<Button>: font_size: 40 size: 170,75 color: 0,1,0,1<Widgets>: Button: pos: root.x, root.top - self.height text: "Kivy" Button: pos: 170,0 text: "Tutorials"我在终端上获得以下输出:$ python main.py [INFO ] [Logger ] Record log in /home/nickshu/.kivy/logs/kivy_18-09-12_58.txt[INFO ] [Kivy ] v1.11.0.dev0, git-038acbf, 20180912[INFO ] [Python ] v3.6.5 |Anaconda, Inc.| (default, Apr 29 2018, 16:14:56) [GCC 7.2.0][INFO ] [Factory ] 195 symbols loaded[INFO ] [Image ] Providers: img_tex, img_dds, img_sdl2, img_pil, img_gif (img_ffpyplayer ignored)[INFO ] [Text ] Provider: sdl2[INFO ] [Window ] Provider: sdl2(['window_egl_rpi'] ignored)[INFO ] [GL ] Using the "OpenGL" graphics system[INFO ] [GL ] Backend used <gl>[INFO ] [GL ] OpenGL version <b'3.0 Mesa 18.0.5'>[INFO ] [GL ] OpenGL vendor <b'Intel Open Source Technology Center'>[INFO ] [GL ] OpenGL renderer <b'Mesa DRI Intel(R) HD Graphics P630 (Kaby Lake GT2) '>[INFO ] [GL ] OpenGL parsed version: 3, 0[INFO ] [GL ] Shading version <b'1.30'>[INFO ] [GL ] Texture max size <16384>[INFO ] [GL ] Texture max units <32>[INFO ] [Window ] auto add sdl2 input provider[INFO ] [Window ] virtual keyboard not allowed, single mode, not docked[INFO ] [ProbeSysfs ] device match: /dev/input/event6下面的窗口显示!有谁知道我做错了什么?这些是我的权限/dev/input/event6crwxrwxr-- 1 root input 13, 70 Sep 11 23:47 /dev/input/event6
