return database_name == ':memory:' or 'mode=memory' in database_name TypeError: 'PosixPath' 类型的参数不可迭代

Question

我正在用 django 制作一个 webapp。我尝试将它部署在 pythonanywhere 上，一切正常，但最后当我尝试使用python manage.py collectstatic它收集静态文件时，出现了以下错误：

return database_name == ':memory:' or 'mode=memory' in database_name
TypeError: argument of type 'PosixPath' is not iterable

提出一些想法，我该如何解决它。

这是我的 setting.py 文件

import os
from pathlib import Path

# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = Path(__file__).resolve().parent.parent

    },
    {

    },
]

# Static files (CSS, JavaScript, Images)

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR / 'static/')

Answer 1

如果您使用的是 Django v3.1，那么您可以尝试str()在settings.py文件中放置数据库路径。这是因为 SQLite 只接受字符串并且 Django v3.1settings.py返回一个pathlib.Path对象。

# settings.py

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

我遇到了同样的问题，并在这里找到了答案：https : //forum.djangoproject.com/t/django-tutorial-python-manage-py-startapp-polls-fails/2718

Answer 2

#在settings.py中执行

# Database
# https://docs.djangoproject.com/en/3.1/ref/settings/#databases

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

问题是这样的：

BASE_DIR = Path(__file__).resolve().parent.parent

两者type(BASE_DIR)和type(BASE_DIR / 'db.sqlite3')都是<class 'pathlib.PosixPath'>

Answer 3

也许你有一个错字，“，”用了“/”。STATIC_ROOT = os.path.join(BASE_DIR, '静态')
