Page not found (404)
Request Method: GET
Request URL:    http://78.198.124.245/
Directory indexes are not allowed here.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False,and Django will display a standard 404 page.

什么“这里不允许使用目录索引”.意思？什么是目录索引？

我用Google搜索,我发现所有结果都与提供静态文件有关.但是,我不认为我这样做.这个错误是什么意思？
