python - 防止 Kivy 留下调试信息

Question

我有一个简单的 Kivy 界面，它也使用终端。

示例代码:

import kivy

kivy.require('1.0.6')

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

class MyApp(App):
    def build(self):
        return Label(text = 'Hello')

MyApp().run()

问题是，每当我启动脚本时，我都会得到这个:

[INFO   ] [Logger      ] Record log in C:\Users\Simon\.kivy\logs\kivy_18-05-12_37.txt
[INFO   ] [Kivy        ] v1.10.0

我发现这是Kivy的自动调试信息。我该如何阻止它们(或至少隐藏以便我可以使用终端)？

如docs所示，您应该只执行以下操作:

import os
os.environ["KIVY_NO_CONSOLELOG"] = "1"

import kivy
...
