我的 Django 应用程序无法通过 TypeError 连接到数据库

Question

我的 Django Web 应用程序无法运行，因为通过我的数据库连接出现 TypeError。

  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/django/db/backends/sqlite3/base.py", line 198, in get_new_connection
    conn = Database.connect(**conn_params)
TypeError: Can't convert 'int' object to str implicitly

错误似乎发生在数据库尝试使用连接参数进行连接时。另外，我正在尝试使用凭据打开我的数据库 (sqlite)，并且连接成功。

其他 django 命令如 python manage.py flush 无法通过无法建立的数据库连接工作。

settings.py 文件：

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

我的完整追溯：
