Django执行迁移时已安装rest_framework_simplejwt仍报ModuleNotFoundError

执行Django迁移操作时触发如下错误：

ModuleNotFoundError: No module named 'rest_framework_simplejwt'

已通过pip验证库已安装：

pip show djangorestframework-simplejwt 
Name: djangorestframework-simplejwt 
Version: 3.2.2 
Summary: A minimal JSON Web Token authentication plugin for Django REST Framework Home-page: https://github.com/davesque/django-rest-framework-simplejwt Author-email: davesque@gmail.com License: MIT Location: \Programs\Python\Python311\Lib\site-packages 
Requires: django, djangorestframework, pyjwt Required-by:

settings.py中INSTALLED_APPS已包含相关应用：

INSTALLED_APPS = [
    'app',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'corsheaders',
    'rest_framework',
    'rest_framework_simplejwt',
    'rest_framework_simplejwt.token_blacklist'
]

REST_FRAMEWORK认证配置如下：

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework_simplejwt.authentication.JWTAuthentication',
    )
}

SIMPLE_JWT详细配置：

from datetime import timedelta
SIMPLE_JWT = {
    "ACCESS_TOKEN_LIFETIME": timedelta(minutes=5),
    "REFRESH_TOKEN_LIFETIME": timedelta(days=1),
    "ROTATE_REFRESH_TOKENS": True,
    "BLACKLIST_AFTER_ROTATION": True,
    "UPDATE_LAST_LOGIN": False,

    "ALGORITHM": "HS256",
    "SIGNING_KEY": SECRET_KEY,
    "VERIFYING_KEY": "",
    "AUDIENCE": None,
    "ISSUER": None,
    "JSON_ENCODER": None,
    "JWK_URL": None,
    "LEEWAY": 0,

    "AUTH_HEADER_TYPES": ("Bearer",),
    "AUTH_HEADER_NAME": "HTTP_AUTHORIZATION",
    "USER_ID_FIELD": "id",
    "USER_ID_CLAIM": "user_id",
    "USER_AUTHENTICATION_RULE": "rest_framework_simplejwt.authentication.default_user_authentication_rule",

    "AUTH_TOKEN_CLASSES": ("rest_framework_simplejwt.tokens.AccessToken",),
    "TOKEN_TYPE_CLAIM": "token_type",
    "TOKEN_USER_CLASS": "rest_framework_simplejwt.models.TokenUser",

    "JTI_CLAIM": "jti",

    "SLIDING_TOKEN_REFRESH_EXP_CLAIM": "refresh_exp",
    "SLIDING_TOKEN_LIFETIME": timedelta(minutes=5),
    "SLIDING_TOKEN_REFRESH_LIFETIME": timedelta(days=1),

    "TOKEN_OBTAIN_SERIALIZER": "rest_framework_simplejwt.serializers.TokenObtainPairSerializer",
    "TOKEN_REFRESH_SERIALIZER": "rest_framework_simplejwt.serializers.TokenRefreshSerializer",
    "TOKEN_VERIFY_SERIALIZER": "rest_framework_simplejwt.serializers.TokenVerifySerializer",
    "TOKEN_BLACKLIST_SERIALIZER": "rest_framework_simplejwt.serializers.TokenBlacklistSerializer",
    "SLIDING_TOKEN_OBTAIN_SERIALIZER": "rest_framework_simplejwt.serializers.TokenObtainSlidingSerializer",
    "SLIDING_TOKEN_REFRESH_SERIALIZER": "rest_framework_simplejwt.serializers.TokenRefreshSlidingSerializer",
}

已尝试以下操作但未解决问题：

• 安装不同版本的djangorestframework-simplejwt
• 多次验证库的安装状态
• 反复检查settings.py中的各项配置

目前无法定位问题根源，希望得到排查思路或解决方案。
