我是编程和Django的新手。我开始关注带有Django教程的Tango，我正在通过在“INSTALLED_APPS”元组下的“settings.py”中键入“rango”创建一个名为“rango”的新应用程序。我按照说明尝试在命令提示符下运行服务器。我收到了以下错误
C:\Python34\Scripts\tango_with_django_project> python manage.py startapp rango
Traceback (most recent call last):
File "C:\Python34\lib\site-packages\django\apps\config.py", line 118, in create
cls = getattr(mod, cls_name)
AttributeError: 'module' object has no attribute 'staticfilesrango'
During handling of the above exception, another exception occurred:

我已经在visual studio和pycharm上尝试了这个，在python3.5和3.4上尝试过，卸载并重新安装了python，并重新启动了pip install和django。请帮忙！
