python3 日志检索异常raise KeyError(key)，KeyError: 'formatters'

Trse KeyError(key)aceback (most recent call last):

KeyError: 'formatters'

原因分析，python3启动时，检索的不是项目包下的目录文件，所以日志文件必须指明路径。我原来的日志方式是：

logging.config.fileConfig('resources/wechat_read_add.conf')
logger = logging.getLogger()

修改为：

from os import path
log_file_path = path.join(path.dirname(path.abspath(__file__)), 'resources/logging.conf')
logging.config.fileConfig(log_file_path)
#logging.config.fileConfig('resources/logging.conf')
logger = logging.getLogger()
