python的logging无法输出到文件?

Question

logging配置如下:

logging.basicConfig(level=logging.DEBUG,\

format="%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s",\
datefmt="%a, %d %b %Y %H:%M:%S",\
filename="i2_insert_equipments.log",\
filemode="w")

但当在代码中使用logging.info的时候，目录下无日志文件生成。但当在控制台中运行的时候，是可以正常运行的，有知道这种现象如何解决的么? 望告知一下，谢谢。

If you don’t know how to use it, I’ll give you an example

#! /usr/bin/env python

import sys
import logging

def add_log_file(infile=None):
    logger = logging.getLogger()
    if infile is not None:
        handler = logging.FileHandler(infile)
    else:
        handler = logging.StreamHandler()
    logger.handlers.append(handler)
    return

def main():
    for c in sys.argv[1:]:
        add_log_file(c)
    for c in sys.argv[1:]:
        logging.error('%s'%(c))


main()

The problem with filename is that you specify an absolute path and then try again, filemode="w". If you do this, a new file will be generated every time,

Answer 3

The environment under the interactive command line is different, especially for certain operations involving files and systems. For example, you can try creating a new process under the interactive command line.
