防止 Kivy 留下调试消息

问题描述 投票:0回答:3

我有一个简单的 Kivy 界面,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,我都会得到以下信息:

[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。我如何阻止它们(或者至少隐藏起来以便我可以使用终端)?

文档所示,您应该只执行以下操作:

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

import kivy
...

现在您可以通过设置

Config
来设置您想要查看哪种日志。 您可以选择
trace
debug
info
warning
error
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。您在第一次运行时仍然会看到它们。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。因此,如果您想查看错误和回溯,设置它不是一个明智的选择。

  1. 找到config.py文件的路径:

    • 在终端中运行以下Python命令:
    • python -c“导入操作系统;导入kivy; print(os.path.join(os.path.dirname(kivy.file), 'config.py'))"
    • 此命令将打印 config.py 文件的完整路径 Kivy 包。
    • 示例:C:\Users\userName\AppData\Local\Programs\Python\Python311\Lib\site-packages\kiv
