沒有名為rest_framework的模塊

Question

我已經看到很多人在這里遇到麻煩，而且我總是看到他們說其他人使用pip3或只是pip來安裝它。

但就我而言，我已經使用pip或pip3多次卸載並安裝了id，但它們似乎都無法正常工作。

我也將“ rest_framework”添加到了設置中，但似乎仍然無法正常工作。 請幫幫我

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'
    ]
}

Answer 1

嘗試使用sudo pip install djangorestframework ，我看到了其他SO問題，它似乎可以解決問題。

Answer 2

添加rest_framework之前agenda.apps.AgendaConfig在settings.py文件中安裝的應用程序。 agenda應用似乎在初始化之前使用了rest_framework庫。

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    'rest_framework',
    'agenda.apps.AgendaConfig',

該答案假設您已成功安裝rest_framework並激活了virtualenv
