我已经开始为Django 1.9更新一个小测试项目。我的结构如下：
- myproject
- settings.py
- urls.py
- wsgi.py
- __init__.py
- apps
- __init__.py
- myapp
- admin.py
- cms_app.py
- cms_appconfig.py
- models.py
- urls.py
- views.py
-__init__.py
我得到的错误是：

Importerror: No module named 'myapp'
我添加了包含应用程序的网站后发生错误。 cms_app.py：
# coding=utf-8
from aldryn_apphooks_config.app_base import CMSConfigApp
from cms.apphook_pool import apphook_pool
from django.utils.translation import ugettext_lazy as _
from .models import MyappConfig
class MyApp(CMSConfigApp):
app_config = MyappConfig
app_name = 'myapp'
name = _("myapp")
urls = ['crowdfunding.urls']
apphook_pool.register(MyApp)
urls.py:
# coding=utf-8
from django.conf.urls import patterns, url
from .views import ProjectListView, ProjectDetailView
Urlpatterns = patterns(
'',
url(r'^$', ProjectListView.as_view(),
name="project_list"),
url(r'^(?P<slug>[^/]+)$',
ProjectDetailView.as_view(),
name="project_details"),
)
项目urls.py：
from __future__ import absolute_import, print_function, unicode_literals
from cms.sitemaps import CMSSitemap
from django.conf import settings
from django.conf.urls import * # NOQA
from django.conf.urls.i18n import i18n_patterns
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
admin.autodiscover()
urlpatterns = i18n_patterns(
'',
url(r'^admin/', include(admin.site.urls)), # NOQA
url(r'^accounts/', include('allauth.urls')),
url(r'^myapp/', include('myproject.apps.myapp'), name="myapp"),
url(r'^sitemap\.xml$', 'django.contrib.sitemaps.views.sitemap',
{'sitemaps': {'cmspages': CMSSitemap}}),
url(r'^select2/', include('django_select2.urls')),
url(r'^', include('cms.urls')), )
# This is only needed when using runserver.
if settings.DEBUG:
urlpatterns = patterns(
'',
url(r'^media/(?P<path>.*)$',
'django.views.static.serve', # NOQA
{'document_root': settings.MEDIA_ROOT,
'show_indexes': True
}), ) + staticfiles_urlpatterns() + urlpatterns # NOQA
我尝试过几个例子，例如直接导入项目urls.py中的视图，然后给我一个“apps”无法找到的错误，这对我来说是一个奇怪的错误。我还删除了项目urls.py中的“名称”，并查看了cms_app.py，如果没有正确给出应用程序名称（我认为这是正确的）。
settings.py包含我的项目：
INSTALLED_APPS = [
'djangocms_admin_style',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.admin',
'django.contrib.sites',
'django.contrib.sitemaps',
'django.contrib.staticfiles',
'django.contrib.messages',
...
'myproject',
'myproject.apps.myapp'
]
我之前没有看到过这个错误（在Django 1.8中），目前我在想，它与urls.py（s）和app加载有关。我确信这个应用程序在1.8中工作但是我找不到有关从1.8到1.9的更改的信息会产生这样的错误。所以我请你帮帮我，找到解决方案。
更新 我现在添加了一个/apps/myapp/apps.py（根据Django 1.9指南），内容如下：
# -*- coding: utf-8 -*-
from django.apps import AppConfig
class Myapp(AppConfig):
name = 'myapp'
verbose_name = 'My App Test'
并在apps / myapp / init .py：
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
__version__ = '0.3'
default_app_config = 'myapp.apps.Myapp'
我还从主urls.py中删除了网址模式，并且也按照该指南的建议将其添加到apps / myapp / urls.py中。
现在错误信息有点短：

我认为，它与应用程序加载有关，但我无法弄清楚我做错了什么。
