我看到很多人在这里遇到这个问题，我总是看到他们说其他使用pip 3或只是pip来安装它。
但在我的情况下，我已经卸载了它，并安装了多次id都使用pip或pip 3，他们似乎都不工作。
我已经将“rest_framework”添加到我的设置中，但似乎仍然不起作用。请帮助我

EDIT
Here is my settings

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'agenda.apps.AgendaConfig',
    'rest_framework',

]

REST_FRAMEWORK = {
    # Use Django's standard `django.contrib.auth` permissions,
    # or allow read-only access for unauthenticated users.
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'
    ]
}

正在收集Djangorestframework下载Djangorestframework-3. 7. 3-py 2. py 3-none-any.whl（1. 5 MB）100%|我是一个很好的朋友。|1.5MB 506 kB/s安装收集的软件包：已成功安装djangorestframework-3. 7. 3
还是不行
