python – Django自定义管理仪表板错误

Django Version: 1.4.1
Exception Type: ImportError
Exception Value:    
No module named dashboard

In template /.../lib/python2.7/site-packages/grappelli/dashboard/templates/admin/index.html,error at line 32
31  {% block content %}
32  {% grp_render_dashboard %}
33  {% endblock %}

我可以在更改之前使用grappelli管理界面.
采取的步骤是根据manual.
我将这些添加到我的settings.py中

GRAPPELLI_INDEX_DASHBOARD = 'myproj.dashboard.CustomIndexDashboard'
    ...
TEMPLATE_CONTEXT_PROCESSORS = (
    "django.contrib.auth.context_processors.auth","django.core.context_processors.request","django.core.context_processors.i18n",'django.contrib.messages.context_processors.messages',)

    INSTALLED_APPS = (
        'grappelli.dashboard','grappelli','django.contrib.admin',...

dashboard.py位于根目录(myproj)中.它里面有一堂课.

class CustomIndexDashboard(Dashboard):
