没有名为kivy.app的模块

问题描述

所以我想我会玩转，尝试学习Kivy，因为它看起来很有趣.我刚刚开始尝试使他们的示例之一起作用:

So I thought I'd toy around and try and learn Kivy, as it looks interesting. I have just started trying to get one of their examples working:

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

class MyPaintWidget(Widget):
    pass


class MyPaintApp(App):
        def build(self):
            return MyPaintWidget()

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

我收到以下错误:

C:\Kivy-1.8.0-py2.7-win32>python paint.py
Traceback (most recent call last):
  File "paint.py", line 1, in <module>
   from kivy.app import App
ImportError: No module named kivy.app

我已经安装了最新版本的Kivy.我在C:\ Kivy-1.8.0-py2.7-win32 \ kivy \ kivy文件夹中看到app.py.

I have installed the latest version of Kivy. I see "app.py in the C:\Kivy-1.8.0-py2.7-win32\kivy\kivy folder.

另外，这是我的PYTHONPATH:

Also, here is my PYTHONPATH:

>>> import sys
>>> for n in sys.path:
...     print n
...

C:\Kivy-1.8.0-py2.7-win32\Python27\lib\site-packages\setuptools-2.0.1-py2.7.egg
C:\Kivy-1.8.0-py2.7-win32\Python27\lib\site-packages\pywin32-218-py2.7-win32.egg

任何帮助将不胜感激.谢谢.

Any help would be greatly appreciated. Thank you.

推荐答案

我将脚本命名为kivy.py时遇到了此错误消息，因为python首先在当前目录中查找该依赖项，因此它从未看到真实 kivy软件包.

I ran into this error message when I named the script kivy.py, because python looks first in the current directory to fill the dependency, so it never sees the real kivy package.

重命名脚本已为我修复.

Renaming the script fixed it for me.
