Как переустановить библиотеку журналов для Python 3?

/ 23 мая 2019

Я получаю сообщение об ошибке при выполнении самой простой регистрации в python 3. Я делаю что-то не так или есть способ переустановить модуль регистрации?

Я обновился с 3.6.5 до 3.7.3, но у меня та же проблема. Пробовал разные уровни логирования, но там тоже не повезло. 

In [2]: import logging as l
   ...:
   ...: #create and configure l
   ...: LOG_FORMAT="%(Levelname)s %(asctime)s - %(funcName)s - %(message)s"
   ...: l.basicConfig(filename="mailExtractor.log",
   ...:         format=LOG_FORMAT,
   ...:         level=l.DEBUG,
   ...:         filemode="w")
   ...:
   ...:

In [3]: l.info("hej")

Вы должны использовать levelname в строке формата, а не Levelname: 

>>> import logging as l
>>> LOG_FORMAT="%(levelname)s %(asctime)s - %(funcName)s - %(message)s"
>>> l.basicConfig(filename="mailExtractor.log", 
                  format=LOG_FORMAT, level=l.DEBUG, filemode="w")
>>> l.info("hej")

Отображение файла дает: 

⚡ cat mailExtractor.log 
INFO 2019-05-22 20:00:23,465 - <module> - hej
...
