您的settings.py 缺少模板目录。

你应该添加

TEMPLATES = [ { "BACKEND": "django.template.backends.django.DjangoTemplates", "DIRS": ["/absolute/path/to/your/templates/",], "APP_DIRS": True, "OPTIONS": { "context_processors": [ "django.template.context_processors.debug", "django.template.context_processors.request", "django.contrib.auth.context_processors.auth", "django.contrib.messages.context_processors.messages", ], }, }, ]
