我已经在logging.config文件中配置了日志记录。我创建了一个类,可以在其中访问此配置文件,启用/禁用记录器并记录一些Info消息。我正在需要记录日志的所有模块中导入此类。当我尝试登录到文件时,出现此错误信息。我无法理解此错误的含义。
在第959行的文件“ /usr/local/lib/python3.6/configparser.py”
getitem引发KeyError(key)KeyError:“格式化程序”

最佳答案
当我尝试从不在项目根目录下的python脚本加载配置时,我遇到了类似的问题。我发现的是:logging.config.fileConfig
依赖于configparser,并且在使用绝对路径初始化时遇到问题。尝试相对路径。
更换
fileName = path.join(path.split(path.dirname(path.abspath(__file__)))[0], "logging.config")
与类似的东西:
## get path tree from project root and replace children from root with ".."
path_rslv = path.split(path.dirname(path.abspath(__file__)))[1:]
fileName = path.join(*[".." for dotdot in range(len(path_rslv)], "logging.config")
