Question

我是django的新手，我正在尝试按照Need a minimal Django file upload example说明创建文件上传页面。但是，我一直得到＆＃34;不支持导入文件＆＃34;错误。

实际错误似乎在这里发生：

C:\Users\AppData\Local\Continuum\Anaconda\lib\importlib\__init__.py in import_module
            __import__(name) ...

完整追溯：

Answer 1

这是您的错误发生的地方：

url(r'^$', 'http://127.0.0.1:8000/home/', name='home'),

作为评论者的建议，这应该是：

from .views import view_name
url(r'^$', view_name, name='home'),
