python - 无法打开数据库文件 - Mayan EDMS

Question

我使用的是 Ubuntu 16.04，我安装了 PyCharm 专业版，这样我就可以轻松运行 Django。

我从 https://gitlab.com/mayan-edms/mayan-edms 克隆了 Mayan EDMS 在我安装了所有需要的包以在 PyCharm 中运行它之后。

但我无法运行它，因为出现错误“无法打开数据库文件”。

我是 Django 的新手，不知道该怎么做。教程中没有提到如何解决这个问题。

The above exception was the direct cause of the following exception:

Answer 1

您需要创建初始数据库，该数据库在开发中默认为 SQLite 数据库。 SQLite 是一个单文件数据库系统。执行:

./manage.py initialsetup

这将创建一个初始数据库，将架构迁移到最新版本并使用一些默认对象填充数据库以使其可用。
