Question

我有一个简单的Kivy接口也使用终端。

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()

问题在于每当我启动脚本时，我都会得到这个：

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

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

现在您可以通过设置 Config 来设置您想要查看的日志类型。您可以选择 trace、debug、info、warning、error 或 critical

之一

from kivy.config import Config
# your code ...

if __name__ == '__main__':
    # path of the log directory
    Config.set('kivy', 'log_dir', 'your_chosen_log_dir_path')
    
    # filename of the log file
    Config.set('kivy', 'log_name', "anything_you_want_%y-%m-%d_%_.log")
    
    # Keep log_maxfiles recent logfiles while purging the log directory. Set ‘log_maxfiles’ to -1 to disable logfile purging (eg keep all logfiles).
    Config.set('kivy', 'log_maxfiles', 1000)

    # minimum log level which is what you need to not see kivy's default info logs
    Config.set('kivy', 'log_level', 'error')
    
    # apply all these changes
    Config.write()

请记住，设置配置变量并运行程序不会立即停止默认调试消息。您仍然会在第一次运行时看到它们。这是因为 Kivy 在第一次运行时设置了配置变量，然后在接下来的运行中应用它。因此，您需要运行两次才能看到效果。

设置 os.environ["KIVY_NO_CONSOLELOG"] = "1" 确实会删除调试消息，但它也不允许您查看错误和关键消息。所以如果你想看到错误和回溯，设置它不是一个明智的选择。
