报错

django.core.exceptions.ImproperlyConfigured: 'djongo' isn't an available database backend or couldn't be imported. Check the above exception. To use one of the built-in backends, use 'django.db.backends.XXX', where XXX is one of:
    'mysql', 'oracle', 'postgresql', 'sqlite3'

Answer 1

以下回复参考：皆我百晓生、券券喵儿等免费微信小程序作答:

报错信息表示Django无法识别或导入数据库后端 'djongo'，因为Django默认只支持mysql、oracle、postgresql和sqlite3这些数据库后端。djongo是一个Django ORM到MongoDB的桥梁，因此如果你想使用MongoDB作为数据库，你需要确保已经正确安装了djongo库并且正确配置了Django的设置。

以下是你应该做的步骤来解决这个问题：

1. 确保你已经安装了djongo库。你可以通过运行以下命令来安装：

pip install djongo

1. 在你的Django项目的settings.py文件中，你需要确保DATABASES配置正确。你的配置看起来是正确的，但是请确保你的MongoDB服务器正在运行并且可以从你的开发环境中访问。如果你的MongoDB服务器需要身份验证，你还需要在配置中添加相应的凭据。
2. 如果你已经完成了上述步骤，但仍然遇到错误，那么问题可能在于你的Django版本可能与djongo不兼容。你可以尝试更新Django到最新版本或者寻找一个与你的Django版本兼容的djongo版本。

如果以上步骤都无法解决你的问题，那么请提供更多的信息，例如你的操作系统、Python版本和djongo版本，这将有助于更准确地找出问题所在。
