settings.py，TypeError：/ 不支持的操作数类型：“str”和“str”

Question

我在尝试迁移时收到此错误消息：

line 82, in <module>
    'NAME': BASE_DIR / 'db.sqlite3',
TypeError: unsupported operand type(s) for /: 'str' and 'str'

第 82 行是这里的第四行：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}

这是settings.py文件的所有代码（我取出了密钥）：

任何想法？我不明白的是我从未接触过第 82 行，那是文件中的代码。我添加的代码位于顶部：

import os
from pathlib import Path

# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
TEMPLATE_DIR = os.path.join(BASE_DIR,'templates')

然后在模板中，我添加了：

'DIRS': [TEMPLATE_DIR,],

最后在 INSTALLED_APPS 中，我添加了：

'appTwo'

谢谢

Answer 1

您正在尝试将一个字符串除以一个字符串。要连接路径的两个部分，请执行以下操作：

os.path.join(BASE_DIR, 'db.sqlite3')

Answer 2

将第 80 行替换为：

'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),

它对我的项目有用希望它也对你有用
