“ImportError：没有名为 urls 的模块”出现在 Django admin 中答案

【问题标题】："ImportError: No module named urls" occurs in Django admin“ImportError：没有名为 urls 的模块”出现在 Django admin 中
【发布时间】：2012-12-09 18:32:33
【问题描述】：

Django：1.3.5
nginx：1.2.6
uwsgi：1.0.5

我的 django 应用在 nginx 和 uwsgi 上运行。打开管理页面时，出现 500 错误。这个错误是“ImportError: No module named urls”。

运行命令“python manage.py runserver”并打开管理页面，没有出现500错误。

在 urls.py 上评论管理员，然后不会发生错误。

这个错误只发生在nginx和uwsgi上。

我该如何解决？

urls.py

from django.conf.urls.defaults import *
from django.conf import settings
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
                       (r'^blog/', include('myApp.blog.urls')),
                       (r'^admin/', include(admin.site.urls))
                       )

wsgi.py

import os
import sys
import site

reload(sys)
sys.setdefaultencoding('utf-8')
sys.path.append('/path/to/myApp/')

site.addsitedir('/usr/lib/python2.6/site-packages')
os.environ['DJANGO_SETTINGS_MODULE'] = 'myApp.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

【问题讨论】：

也发布您的settings.py（删除机密数据）
@Hedde 我发布了 settings.py (INSTALLED_APPS)。
打开一个 python shell 并输入： from django.conf.urls.defaults import * 如果它不能导入并显示错误，所以没有安装 urls 包但是如果 python shell 可以导入，也许你存在干扰 url 解析过程的重复项。
谢谢。 python shell 可以导入。我尝试重新安装 django，但出现错误。删除cookie，然后登录页面正常显示。但是，点击登录按钮，出现500错误。
你能告诉我错误吗？？？

【解决方案1】：

你如何开始你的 uwsgi 进程？您的 uwsgi 进程需要从项目根目录的位置启动。

我通过给它一个PROJECT_HOME 环境变量来配置我的uwsgi 初始化文件，它在我的进程用户的.bash_profile 文件中定义。

在我的进程用户.bash_profile 中，我有：-

export PROJECT_HOME=/var/www/myproject

然后，在我的 uwsgi 初始化文件中，我有：-

[uwsgi]

if-env = PROJECT_HOME
chdir = %(_)
touch-reload = %(_)/uwsgi.ini
daemonize = %(_)/myproject.log
endif =

if-env = VIRTUAL_ENV
virtualenv = %(_)
endif = 

socket = 127.0.0.1:3030
pidfile=/tmp/myproject.pid-3030
processes = 4
module = django.core.handlers.wsgi:WSGIHandler()
env = DJANGO_SETTINGS_MODULE=myproject.settings
master = True
vacuum = True
max-requests = 5000
logdate = True

enable-threads = True
single-interpreter = True

chdir 这个uwsgi.ini 文件中的配置告诉我的uwsgi 进程从该目录启动该进程并将该目录包含在PYTHONPATH 中，以便可以找到我的项目的模块。

如果您还定义了VIRTUAL_ENV 环境，正如您在uwsgi.ini 文件中的VIRTUAL_ENV 配置中看到的那样，VIRTUAL_ENV 目录也包含在PYTHONPATH 中，用于uwsgi 进程。

要运行我的 uwsgi 进程，只需运行以下命令即可：-

uwsgi --ini /var/www/myproject/uwsgi.ini

这可以确保你的所有 python 模块（比如你的urls.py）被你的 uwsgi 进程正确加载。希望这会有所帮助！
