意外的关键字参数“传播”

Question

我正在使用 python 的日志记录模块。对于配置，我正在尝试创建一个 yaml 格式的配置文件。但我收到错误

ValueError: Unable to configure handler 'file_handler': __init__() got an unexpected keyword argument 'propagate'

而我可以使用它logger.propagate = False。 我正在关注python logging yaml config，他们使用了相同的配置并能够解析它。

这就是我的 yaml 的样子

version: 1

formatters:
  simple:
    format: "%(asctime)s %(funcName)s %(levelname)s %(message)s"

handlers:
  console:
    class: logging.StreamHandler
    level: INFO
    formatter: simple

  file_handler:
    class: logging.FileHandler
    level: INFO
    filename: test_{}.log
    formatter: simple
    propagate: False

loggers:
  dev:
    handlers: [console, file_handler]
  test:
    handlers: [file_handler]
root:
  handlers: [file_handler]

这是我遇到的错误

 File "/usr/lib/python3.6/logging/config.py", line 565, in configure
    handler = self.configure_handler(handlers[name])
  File "/usr/lib/python3.6/logging/config.py", line 738, in configure_handler
    result = factory(**kwargs)
TypeError: __init__() got an unexpected keyword argument 'propagate'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "logging_manager.py", line 34, in <module>
    LoggingManager()
  File "logging_manager.py", line 24, in __init__
    logging.config.dictConfig(config)
  File "/usr/lib/python3.6/logging/config.py", line 802, in dictConfig
    dictConfigClass(config).configure()
  File "/usr/lib/python3.6/logging/config.py", line 573, in configure
    '%r: %s' % (name, e))
ValueError: Unable to configure handler 'file_handler': __init__() got an unexpected keyword argument 'propagate'

我在这里错过了什么？

编辑： 我正在使用环境

Python 3.6.9 (default, Oct  8 2020, 12:12:24)
[GCC 8.4.0] on linux

传播是记录器的属性，而不是处理程序的属性。您需要将其从您拥有的位置移除并将其放入记录器部分：

loggers:
  dev:
    handlers: [console, file_handler]
    propagate: False <---------------------- HERE for example
  test:
    handlers: [file_handler]
