def init_log():

    logger = logging.getLogger()
    log_path = os.path.abspath(os.path.join(os.path.dirname(__file__), 'logs'))
    print('log_path:', log_path)
    # 设置日志记录等级
    logger.setLevel(logging.INFO)
    # interval 滚动周期，
    # when="MIDNIGHT", interval=1 表示每天0点为更新点，每天生成一个文件
    # backupCount  表示日志保存个数
    file_handler = TimedRotatingFileHandler(
        filename=log_path, when="MIDNIGHT", interval=1, backupCount=30
    )
    # filename="mylog" suffix设置，会生成文件名为mylog.2020-02-25.log
    file_handler.suffix = "%Y-%m-%d.log"
    # extMatch是编译好正则表达式，用于匹配日志文件名后缀
    # 需要注意的是suffix和extMatch一定要匹配的上，如果不匹配，过期日志不会被删除。
    file_handler.extMatch = re.compile(r"^\d{4}-\d{2}-\d{2}.log$")
    # 定义日志输出格式
    file_handler.setFormatter(
        logging.Formatter(

        )

查了很多资料，FQ也没找到相关问题。后来各种试，发现是因为自己手动创建了logs文件夹在项目目录下，而配置时又指定了日志名为logs，导致它创建不出来logs就抛异常了~

抛的这异常也是够不明不白的~~
