简单Kivy应用程序崩溃（版本解锁锁）

努力甚至可以运行简单的Kivy应用程序时，我收到以下错误：简单Kivy应用程序崩溃（版本解锁锁）

的应用程序的代码如下：

from kivy.app import App 
from kivy.uix.label import Label 

class MyApp(App): 

    def build(self): 
     return Label(text='Hello world') 

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

为什么即使最基本的程序似乎崩溃的任何想法？

我删除并重新安装了Python，因为我安装了python 2.7和python 3.6，并且我想我打开了Kivy的安装....似乎现在正在工作。 –

这是一个typo代码kivy.clock的变化。它基本上调用了两次方法，它不应该（不释放线程锁定）。

我不确定是因为Cython还是因为Windows，但我认为错误应该返回ThreadError。 Kivy中的数量太少，因此我不确定它为什么会返回错误类型的错误。
