Django / Python應用程序日志記錄不起作用

Question

我是Python的完全noob。 現在我正在設置一個新項目，在某些時候我不得不調用./manage.py syncdb 。 這是我收到的：

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/logging/handlers.py", line 820, in _connect_unixsocket
    self.socket.connect(address)
FileNotFoundError: [Errno 2] No such file or directory

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/logging/config.py", line 557, in configure
    handler = self.configure_handler(handlers[name])

    self.socket.connect(address)

During handling of the above exception, another exception occurred:

    '%r: %s' % (name, e))
ValueError: Unable to configure handler 'syslog': [Errno 2] No such file or directory

任何想法如何解決問題？

這是我的settings.py

# DJANGO SETTINGS FILE - ideas from http://justcramer.com/2011/01/13/settings-in-django/

import os, sys
import importlib

## Import our defaults (globals)
from .conf.default import *

## Inherit from environment specifics
DJANGO_CONF = os.environ.get('DJANGO_CONF', 'default')
sys.path.insert(0, os.getcwd())
if DJANGO_CONF != 'default':
    module = __import__(DJANGO_CONF, globals(), locals(), ['*'], 1)
    for k in dir(module):
        locals()[k] = getattr(module, k)

## Import local settings
try:
    from .local_settings import *
except ImportError as e:
    pass

## Remove disabled apps
if 'DISABLED_APPS' in locals():
    INSTALLED_APPS = [k for k in INSTALLED_APPS if k not in DISABLED_APPS]

    MIDDLEWARE_CLASSES = list(MIDDLEWARE_CLASSES)
    DATABASE_ROUTERS = list(DATABASE_ROUTERS)
    TEMPLATE_CONTEXT_PROCESSORS = list(TEMPLATE_CONTEXT_PROCESSORS)

    for a in DISABLED_APPS:
        for x, m in enumerate(MIDDLEWARE_CLASSES):
            if m.startswith(a):
                MIDDLEWARE_CLASSES.pop(x)

        for x, m in enumerate(TEMPLATE_CONTEXT_PROCESSORS):
            if m.startswith(a):
                TEMPLATE_CONTEXT_PROCESSORS.pop(x)

        for x, m in enumerate(DATABASE_ROUTERS):
            if m.startswith(a):
                DATABASE_ROUTERS.pop(x)

if 'djcelery' in INSTALLED_APPS:
    import djcelery
    djcelery.setup_loader()

# DONT TOUCH THESE - overwritten by fabfile.py

VERSION = "UNVERSIONED"

DEFAULT_LOG = 'console'

Answer 1

我發現了什么問題。 而不是/dev/log我的OS X版本有/var/run/syslog 。 所以：

if DEBUG or not os.path.exists('/dev/log'):
    LOGGING['handlers']['syslog']['address'] = '/var/run/syslog'

Answer 2

嘗試在settings.py中設置DEFAULT_LOG

if DEBUG or not os.path.exists('/dev/log'):
    DEFAULT_LOG = 'console'
else:
    DEFAULT_LOG = 'syslog'

Answer 3

當syslog服務本身沒有運行時，我也看到了這個錯誤。 運行sudo service syslog-ng start為我解決了這個問題。
