Question

我正在使用Ubuntu 16.04，并且安装了PyCharm专业版，因此可以轻松运行Django。

我从https://gitlab.com/mayan-edms/mayan-edms克隆了Mayan EDMS 然后我安装了所有必需的软件包，以便在PyCharm中运行它。

但是我无法运行它，因为出现错误“无法打开数据库文件”。

我是Django新手，不知道该怎么做。教程中没有任何关于修复此问题的内容。

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

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是单个文件数据库系统。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。
