Centos 7 上的发明树

Question

过去两天我一直在尝试在 CentOS 7 上安装 InvenTree，当然，因为 CentOS 不符合使用命令 'wget -qO install.sh https://get.inventree.org && bash install.sh'，我必须手动安装所有内容。所以，我安装了 Python 3.8，安装了 PostgreSQL，并克隆了 InvenTree 存储库。我遇到了很多问题，但到目前为止没有什么是我解决不了的。无论如何，事不宜迟，我会解释我的问题。

当我运行命令'python3.8 manage.py migrate'时，出现以下错误：

Traceback (most recent call last):

    from _curses import *
ModuleNotFoundError: No module named '_curses'

但是，我已经使用命令“sudo yum install python38-devel ncurses-devel”安装了 python38-devel 和 ncurses-devel。可以肯定的是，我还删除了 python 环境并创建了一个新环境：

deactivate
rm -rf inventree-env
python3.8 -m venv inventree-env
source inventree-env/bin/activate
cd InvenTree
pip install -r requirements.txt

我已经安装了缺少的模块之一 psycopg2：'pip install psycopg2' 并且我已经在控制台中定义了用于连接到 PostgreSQL 的环境变量：

export INVENTREE_DB_ENGINE='django.db.backends.postgresql'
export INVENTREE_DB_NAME='InvenTree'
export INVENTREE_DB_USER='MyUser'
export INVENTREE_DB_PASSWORD='MyPassword'
export INVENTREE_DB_HOST='localhost'
export INVENTREE_DB_PORT='5432'

我还在 settings.py 中定义了 Static 和 Media 文件夹的路径，在 config.py 中定义了备份文件夹。

然而，在进行了所有必要的调整之后，我仍然遇到上述错误。

让我给你一些关于路径的更多细节：整个 InvenTree 项目位于 /root 中（我知道这不是很可取，但是......）：

有没有人有什么想法可以帮助我？

PS：我很想使用一个很好的旧 Ubuntu 服务器或 Debian 系统，但不幸的是，我别无选择，只能使用 CentOS 7。

预先感谢您的帮助:)
