我正在尝试登录一个维护配置文件的文件,如下面的目录结构,文件内容如下。
HERE/
|--WORKSPACE/
| |-- PROJECT/
| | |-- project/
| | | |-- confs/
| | | | |-- __init__.py
| | | | |-- custom_handler.py
| | | | |-- log.ini
| | | |-- log.py
log.py:
import os
import logging.config
logging.raiseExceptions = True
curr_dir = os.path.dirname(os.path.realpath(__file__))
CONFIG = os.path.join(curr_dir, 'confs/log.ini')
logging.config.fileConfig(CONFIG)
log.ini:
[loggers]
keys=file
[logger_file]
handlers=file
level=NOTSET
[formatters]
keys=complex
[formatter_complex]
format=%(asctime)s - %(name)s - %(levelname)s - %(module)s : %(lineno)d - %(message)s
[handlers]
keys=file
[handler_file]
class=custom_handler.TRFileHandler
interval=W2
backupCount=2
formatter=complex
level=WARNING
args=('project.log',)
custom_handler.py:
import os
from logging.handlers import TimedRotatingFileHandler
curr_dir = os.path.dirname(os.path.realpath(__file__))
parent_dir = os.path.dirname(curr_dir)
LOGS_DIR = os.path.join(parent_dir, 'logs')
class TRFileHandler(TimedRotatingFileHandler):
def __init__(self, file_name):
if not os.path.isdir(LOGS_DIR):
os.makedirs(LOGS_DIR)
super(TRFileHandler, self).__init__(os.sep.join(LOGS_DIR, file_name))
当我运行以下命令时,我收到了相应的错误。它看起来像一个python路径问题。但我不确定这一点。它适用于'confs'目录级别的python文件。
~HERE$ python WORKSPACE/PROJECT/project/log.py
Traceback (most recent call last):
File "WORKSPACE/PROJECT/project/log.py", line 8, in <module>
logging.config.fileConfig(CONFIG)
File "/usr/lib/python2.7/logging/config.py", line 78, in fileConfig
handlers = _install_handlers(cp, formatters)
File "/usr/lib/python2.7/logging/config.py", line 153, in _install_handlers
klass = _resolve(klass)
File "/usr/lib/python2.7/logging/config.py", line 88, in _resolve
found = __import__(used)
ImportError: No module named custom_handler
答案 0 :(得分:2)
您的sys.path
需要包含project/confs
目录,否则您将无法导入custom_handler
模块。确保是这种情况后再试一次。
更新:我不确定log.py
是设置路径的地方。没有一种正确的方法可以做到这一点 - 有各种关于如何设置Python项目的教程。
