在 django 项目中出现 typeError 错误 [英] Getting a typeError error in django project

问题描述

我为我的新项目创建了一个虚拟环境，安装了 django 并启动了新项目.但是，每当我使用 manage.py 运行一行代码时，我都会收到这个长错误.

I created a virtual environment for my new project, installed django and started the new project. However, whenever i run a line of code with manage.py i get this long error.

数据库入口:

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

推荐答案

似乎 NAME 正在被转换为 pathlib.Path (WindowsPath) 对象而不是字符串，然后不能以与 os.path 需要字符串(不是 100% 确定，因为没有深入调查)

It does seem NAME is being converted to pathlib.Path (WindowsPath) object instead of string which then cannot be used in Django in same way as os.path expects strings (Not 100% sure as did not investigate in depth)

所以在字符串中转换是合适的

So casting in string would be appropriate

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