【原创】源码安装多版本odoo（含odoo12.0、13.0、14.0、15.0、16.0、17.0、18.0）
思路：
前提基于ubuntu22，并且预先配好中国大陆ubuntu安装源：
参考：https://linuxmirrors.cn/use/

一、在ubunt安装好odoo的运行环境依赖：

sudo apt-get update
sudo apt-get install -y python3-pip
sudo apt install git python3-pip build-essential wget python3-dev python3-venv \
    python3-wheel libfreetype6-dev libxml2-dev libzip-dev libldap2-dev libsasl2-dev \
    python3-setuptools node-less libjpeg-dev zlib1g-dev libpq-dev \
    libxslt1-dev libldap2-dev libtiff5-dev libjpeg8-dev libopenjp2-7-dev \
    liblcms2-dev libwebp-dev libharfbuzz-dev libfribidi-dev libxcb1-dev

二、Python 依赖安装好之后，还需要安装一些前端所需的npm依赖包：

sudo apt-get install -y npm
sudo ln -s /usr/bin/nodejs /usr/bin/node

这里如果npm依赖包的安装很慢，请更换淘宝最新的npm源：设置命令如下：
