原因

Django new version(>2.1.x) requires an sqlite library

中和以下大神的答案，解决办法：

Or, if you prefer, use a slightly older version of Django that doesn't require an sqlite library that's newer than your OS has.
Either that, or if you plan on using a database other than sqlite in production, once you modify your settings.py's DATABASES variable to use something other than sqlite, you won't have this problem anymore.

downgrade Django to 2.1.x
remove django database dependency

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}
