尝试运行简单 Kivy 程序时出错 (Windows)

Question

When trying to run the following program on my computer:

# First import an App class from kivy
from kivy.app import App
# Define App subclass
class TutorialApp(App):
    pass
if __name__=="__main__":
    TutorialApp().run()

After I added what was suggested( The last two lines ), I get two syntax errors, the first telling me to delete the colon and the second telling me to remove the indent, and then this:

[INFO              ] Kivy v1.8.0

According to the tutorial I'm following( http://inclem.net/2014/01/09/kivy-crash-course/1_making-a-simple-app/ ), the program should be able to run without problems. I've installed Kivy and Python 3.3.

Answer 1

If that's really your program, the problem is simply that it doesn't do anything. Use TutorialApp().run() to actually start the gui.

Either way, that traceback is not an error.

Answer 2

看起来您缺少pygame的安装 - Kivy 安装未将其作为依赖项引入，因此您需要单独安装它 - 请参阅http://kivy.org/docs/installation/troubleshooting-macosx.html#无法找到任何有价值的窗口提供者错误
