Kivy 未在目录中检测到文件

2022-01-15 00:00:00 python kivy directory

问题描述

我一直在尝试用 kivy 构建一些东西，但是每当我尝试在目录中加载不同的东西时，它都会说在目录中找不到该程序，但我确定它在那里.下面是两个程序的代码和错误.程序(main.py 和 pong.kv)都在 Windows(C:) 中的 pong_directory.py 目录中.非常感谢任何反馈.

I've been trying to build something with kivy, but whenever I try to load a different in a directory, it says that the program isn't found in the directory, when I'm sure it's there. Below is the code for the two programs and the error. The programs(main.py and pong.kv) are both in the directory pong_directory.py in Windows(C:). Any feedback is greatly appreciated.

main.py:

from kivy.app import App
from kivy.uix.widget import Widget


class pongGame(Widget):
    pass


class pongApp(App):
    def build(self):
        return pongGame()


if __name__ == '__main__':
    pongApp().run()

pong.kv:

#:kivy 1.8.0

<PongGame>:    
    canvas:
        Rectangle:
            pos: self.center_x - 5, 0
            size: 10, self.height

    Label:
        font_size: 70  
        center_x: root.width / 4
        top: root.top - 50
        text: "0"

    Label:
        font_size: 70  
        center_x: root.width * 3 / 4
        top: root.top - 50
        text: "0"

如您所见，当我确定它存在时，它表示它在 pong_directory.py 中找不到 pong.kv.如果有人知道发生了什么，我将不胜感激.

As you can see, it's saying that it can't find pong.kv in pong_directory.py, when I'm sure it's there. If anybody has any idea what's going on, I'd greatly appreciate it.

在尝试了建议的错误后，程序仍然具有相同的最终结果，但在 shell 中出现了一个新错误:

After trying what inclement suggested, the program still has the same end result, but in the shell there's a new error:

[DEBUG             ] [App         ] kv <C:pong_directorypong.kv> not found
[DEBUG             ] [Window      ] Ignored <egl_rpi> (import error)
[INFO              ] [Window      ] Provider: pygame(['window_egl_rpi'] ignored)
[DEBUG             ] [Window      ] Display driver windib

我不确定这是否是图形问题，但我在 SE 上发现了一个类似错误的问题(Kivy-python: 运行 Hello world 时出错)，但另一个问题仍然存在.如果有人知道发生了什么反馈，我们将不胜感激.

I'm not sure if it's a graphics problem, but I found a question with a similar error on SE(Kivy-python: error while running Hello world), but the other problem is still there. If anyone has an idea of what's going on feedback is greatly appreciated.

在添加 'import kivy' 和 'kivy.require('1.8.0') 行后 pong.kv 仍然被忽略.

pong.kv was still ignored after adding the lines 'import kivy' and 'kivy.require('1.8.0').

解决方案

不是直接的答案，而是一种可能的解决方法:

Not a direct answer, but a possible work around: 

from kivy.lang import Builder

Builder.load_file('./my_custom_file.kv')

或者，您可以尝试手动加载字符串并完全忘记(删除)kv 文件.

Alternatively you can try loading the string manually and forget (delete) the kv file entirely.

from kivy.lang import Builder

Builder.load_string('''
<PongGame>:    
canvas:
    Rectangle:
        pos: self.center_x - 5, 0
        size: 10, self.height

Label:
    font_size: 70  
    center_x: root.width / 4
    top: root.top - 50
    text: "0"

Label:
    font_size: 70  
    center_x: root.width * 3 / 4
    top: root.top - 50
    text: "0"
''')

如果您想继续使用 pong.kv 文件，我还建议将主应用程序类重命名为 PongApp.我不确定它是否有任何影响，但值得一试.

If you want to continue using the pong.kv file I also suggest renaming the main app class to PongApp. I am unsure if it has any effect but it's worth a shot.
