Ubuntu上的Python ImportError：沒有名爲app.urls的模塊

Question

我最近在學校項目中安裝了Ubuntu，Apache，Python和Django。儘管如此，我仍然遇到了問題。我跟着這tutorial

一切工作如圖所示。我得到了默認的「它的工作！」頁。當我開始真正爲項目添加應用程序時，我的問題就出現了。我收到以下錯誤：

我的目錄都設置如下：

+ srv 
---+ pumpit 
------+ pumpit2 
---------+ conf 
------------+ apache 
---------+ pumpitproj 
------------+ loginhandler 
------------+ main 
------------+ memberplanhandler 
------------+ pumpitproj 
------------+ site_media 

我INSTALLED_APPS和/srv/pumpit/pumpit2/pumpitproj/pumpitproj/settings.py這個樣子的ROOT_URLCONF ：

INSTALLED_APPS = (
    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
    'django.contrib.sites', 
    'django.contrib.messages', 
    'django.contrib.staticfiles', 
    # Uncomment the next line to enable the admin: 
    # 'django.contrib.admin', 
    # Uncomment the next line to enable admin documentation: 
    # 'django.contrib.admindocs', 
    'pumpitproj.loginhandler', 
) 

ROOT_URLCONF = 'pumpitproj.urls' 

我/srv/pumpit/pumpit2/pumpitproj/pumpitproj/urls.py如下：

from django.conf.urls import patterns, include, url 

# Uncomment the next two lines to enable the admin: 
# from django.contrib import admin 
# admin.autodiscover() 

urlpatterns = patterns('', 
    url(r'^login/', include('pumpitproj.loginhandler.urls')), 
) 

我/srv/pumpit/pumpit2/pumpitproj/loginhandler/urls.py如下：

from django.conf.urls import patterns, url 
from loginhandler import views 

urlpatterns = patterns('pumpitproj.loginhandler.views', 
    url(r'^$', 'index'), 
) 

我/srv/pumpit/pumpit2/conf/apache/django.wsgi如下：

import os 
import sys 

root_path = os.path.abspath(os.path.join(os.path.dirname(__file__), '..', '..',$ 
sys.path.insert(0, os.path.abspath(os.path.join(root_path, 'venv/lib/python2.7/$ 
sys.path.insert(0, os.path.abspath(os.path.join(root_path, 'pumpit2'))) 
sys.path.insert(0, os.path.abspath(os.path.join(root_path, 'pumpit2', 'pumpitpr$ 

os.environ['DJANGO_SETTINGS_MODULE'] = 'pumpitproj.settings' 

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

我不知道還有什麼可能需要幫助。我相信這是一件簡單的事情，我完全忽略了。

我花了這麼多時間尋找答案。我似乎發現很多其他人有ImportError問題，但我遇到的那些爲別人工作的答案沒有一個適合我。任何幫助，我可以得到將不勝感激。

更新：我結束了剛剛刪除loginhandler文件夾和重新制作應用程序，並解決了問題。我不知道哪裏出了問題。

雖然，我顯然不知道刪除模塊/應用程序的正確方法，因爲當我嘗試創建新模塊時，它聲明具有該名稱的模塊已經存在。我最終不得不將其命名爲別的東西。

Answer 1

在安裝的應用程序中正確添加您的應用程序名稱，在這裏添加'pumpitproj.loginhandler'，請將其更改爲'loginhandler'並正確設置您的ROOT_URLCONF。

如果您的應用程序之外創建urls.py然後設置

ROOT_URLCONF = 'urls' 

如果你在一個模塊內loginhandler創建urls.py然後設置

ROOT_URLCONF = 'loginhandler.urls' 

也改變

url(r'^login/', include('pumpitproj.loginhandler.urls')) 

至

url(r'^login/', include('loginhandler.urls')) 

My/srv/pumpit/pumpit2/pumpitproj/loginhandler/urls。py如下：

from django.conf.urls import patterns, url 
from loginhandler import views 

urlpatterns = patterns('loginhandler.views', 
    url(r'^$', 'index'), 
) 

嘗試此更改。
