Question

我正在跟进 django 教程，我刚刚使用 pip install django=2.1 安装了 django，并且成功安装，然后使用 django-admin startproject App . 创建了一个项目，之后我尝试使用 {{1} 运行服务器} 并且我得到了一个 python manage.py runserver。

TypeError: argument 1 must be str not WindowsPath

这里是 settings.py：

TypeError: argument 1 must be str, not WindowsPath

我是不是遗漏了什么。请帮忙！此外，stackoverflow 不允许我添加更多信息，因为它说我的问题主要是代码。

Answer 1

问题来了

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

BASE_DIR / 'db.sqlite3' 返回一个 Pathlib 对象（WindowsPath 如果您使用的是 Windows，否则为 PosixPath），而 NAME 实际上期望一个字符串。所以只需将 BASE_DIR / 'db.sqlite3' 更改为 str(BASE_DIR / 'db.sqlite3')

python manage.py runserver: TypeError: argument 1 must be str not WindowsPath
