主/主/ urls.py

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

urlpatterns = patterns('', 
    url(r'^$', include('main.apps.builder.urls')), 
) 

Answer 1

你apps模块必须低于main/main，或者你必须确保你的apps文件夹在sys.path，可能是最好的设置PYTHONPATH。

Answer 2

你在你的settings.py文件添加到INSTALLED_APPS？

也为ramdaz建议每个目录需要一个__init__.py文件，即使它是空的。
