📥 Installing the PyCharm IDE

PyCharm Community Edition is recommended for Odoo development.

Installation via terminal:

sudo apt update
sudo apt upgrade
sudo snap install pycharm-community --classic

Make sure you have:

• at least 4 GB of RAM (8 GB recommended)
• an SSD with at least 5 GB of free space
• a decent screen resolution
• a 64-bit Linux with GLIBC ≥ 2.27

🐍 Installing Python 3.12

Ubuntu does not include Python 3.12 by default. Add the PPA deadsnakes, then install Python:

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.12 python3.12-dev

Also add the required libraries:

sudo apt install build-essential libjpeg-dev libpq-dev libxml2-dev libssl-dev libffi-dev li

📦 Web dependencies & tools

Install the web dependencies required by Odoo:

sudo apt install -y npm
sudo ln -s /usr/bin/nodejs /usr/bin/node
sudo npm install -g less less-plugin-clean-css
sudo apt install -y node-less

Install WKHTMLTOPDF to generate PDF reports:

sudo wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb
sudo dpkg -i libssl1.1_1.1.1f-1ubuntu2_amd64.deb

🗄️ Installing PostgreSQL

Odoo uses PostgreSQL as its database:

sudo apt install postgresql postgresql-client

Create a PostgreSQL user for Odoo:

sudo su - postgres
createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt odoo19
psql
ALTER USER odoo19 WITH SUPERUSER;
\q
exit

📥 Getting the Odoo 19 source code

Install Git, then clone the official repository:

sudo apt install git
git clone https://www.github.com/odoo/odoo --depth 1 --branch 19.0 --single-branch odoo19

⚙️ Configuration in PyCharm

1. Open PyCharm, then Open the odoo19 folder.
2. In Terminal (Alt+F12), create the virtual environment:

sudo apt install python3.12-venv
python3.12 -m venv venv
source venv/bin/activate

1. Install the Python dependencies:

curl -sS https://bootstrap.pypa.io/get-pip.py | python3.12
pip install -r requirements.txt

⚙️ Create the odoo.conf file

In the odoo19 root folder, create a file named odoo.conf :

[options]
admin_passwd = admin
db_host = localhost
db_port = 5432
db_user = odoo19
db_password = ton_mot_de_passe
addons_path = /home/ton_user/odoo19/addons
http_port = 8019

🧠 Adding the Python interpreter in PyCharm

In Settings → Project: odoo19 → Python Interpreter, choose the interpreter of the venv Python 3.12 you created.

In Edit Configurations → + → Python :

• Name : Odoo19
• Interpreter : your Python venv
• Script Path : odoo-bin
• Parameters : -c odoo.conf

🚀 Testing Odoo

Start the project from PyCharm.

Then open in your browser:
