Django Rest 没有明确声明

Question

我正在安装 django rest 框架，当我在 settings.py 的 INSTALLED_APPS 中添加 rest-framework 时，我收到如下错误：

Watching for file changes with StatReloader
Exception in thread Thread-1:
Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 1006, in _gcd_import
  File "<frozen importlib._bootstrap>", line 983, in _find_and_load
  File "<frozen importlib._bootstrap>", line 965, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'rest-framework'

Traceback (most recent call last):

RuntimeError: Model class django.contrib.contenttypes.models.ContentType doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

有什么想法吗？

Answer 1

您似乎从已安装的应用中删除了内容类型。在你的 settings.py 中添加：

INSTALLED_APPS = [
    ...
    "django.contrib.contenttypes",
]
