How to Install Odoo 18 with Pycharm
Enterprise

Enterprise
Introduction
In this slide we’ll discuss the installation of odoo 18 with
pycharm. Odoo 18 is a powerful business management software
known for its enhanced features and ability to streamline
operations. Built with Python 3.10+ for the backend and
PostgreSQL as its database, it provides a reliable and efficient
system. The frontend is driven by JavaScript, ensuring a smooth
user interface. Paired with Ubuntu 22.04 LTS, a stable and
secure operating system with long-term support, Odoo 18 offers
optimal performance and compatibility.

macOS, or
Linux (for

Debian,
Ubuntu, or
RHEL)

Enterprise
We can install PyCharm by downloading the Debian installation file
from the following URL:
PyCharm Community Edition Download
Alternatively, we can install PyCharm using the command line. To do
this, open Terminal (you can press Ctrl + Alt + T to launch Terminal)
and run the following commands
sudo apt-get update
sudo apt-get upgrade
sudo snap install pycharm-community --classic

Enterprise
Step 2: Installing Python 3.12
The latest version of Python 3.12 isn’t available in the default Ubuntu
repositories. To install it, we’ll need to add an alternative repository.
The deadsnakes repository on Launchpad contains various Python
packages, including Python 3.12.
To add the deadsnakes repository, use the following commands:
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update

Enterprise
You can verify the updated list of Python packages using the following
command.
apt list | grep python3.12
You can install Python 3.12 by running the following command:
Install the necessary packages for Python 3, use the following code:
sudo apt-get install python3.12
sudo apt-get install python3.12-dev build-essential libjpeg-
dev libpq-dev libjpeg8-dev libxml2-dev libssl-dev libffi-dev
libmysqlclient-dev libxslt1-dev zlib1g-dev libsasl2-dev libldap2-
dev liblcms2-dev

Enterprise
Step 3: Install Web Dependencies
The next step involves installing the necessary web dependencies.
sudo apt-get install -y npm
sudo ln -s /usr/bin/nodejs/usr/bin/node
sudo npm install -g less less-plugin-clean-css
sudo apt-get install -y node-less
Step 4: Install Wkhtmltopdf
To generate Odoo reports, Wkhtmltopdf needs to be installed. You
can do this by running the following command:
sudo wget
https://github.com/wkhtmltopdf/wkhtmltopdf/releases/downl
oad/0.12.5/wkhtmltox_0.12.5-1.bionic_amd64.deb

Enterprise
Step 5: Install PostgreSQL
The next step is to install PostgreSQL
sudo apt install postgresql postgresql-client
Step 6: Configure a Database User Role for Odoo Databases
Create a new database user by following these instructions. Be sure
to set a password for this user, as you'll need it when creating the
configuration file, so keep it saved.
sudo su - postgres
createuser --createdb --username postgres --no-createrole --
no-superuser --pwprompt odoo18

Enterprise
Next, grant superuser privileges to the specified user.
psql
ALTER USER odoo18 WITH SUPERUSER;
Finally, exit both psql and the Postgres user.
q
exit

Enterprise
Then, use the command below to clone the Odoo code into an ‘odoo18’
directory within your home directory:
git clone https://www.github.com/odoo/odoo --depth 1 --branch
18.0 --single-branch odoo18
sudo apt-get install git
Step 7: Obtain Odoo 18 Source Code
You can acquire the Odoo 18 Community Source code directly from
Odoo's GitHub repository. Alternatively, you can clone it using Git.
First, install Git by running the following command:

Enterprise
Step 8: Open the Odoo Project in PyCharm
Launch PyCharm Community Edition and navigate to the ‘Odoo18’
directory. Once the project is open, you might see a dialogue box
similar to the one shown below. This is for creating a virtual
environment; however, we'll set up the virtual environment via the
terminal, so go ahead and cancel it.

Enterprise
To open the terminal, either click on the icon displayed below or use
the shortcut Alt+F12.

Enterprise
Next, run the following commands to create a virtual environment
using Python 3.12.curl -sS
https://bootstrap.pypyour_venv_namea.io/get-pip.py | python3.12
sudo apt install python3.12-venv
python3.12 -m venv your_venv_namecurl -sS
https://bootstrap.pypa.io/get-pip.py | python3.12
python3.12 -m venv your_venv_name
curl -sS https://bootstrap.pypa.io/get-pip.py | python3.12
python3.12 -m venv your_venv_name

Enterprise
After closing and reopening the terminal, you’ll notice that your
virtual environment is active. The terminal will display an indicator
with the name of your virtual environment, as shown below:
If your virtual environment doesn’t activate automatically, use
the following command.
source your_venv_name/bin/activate

Enterprise
Step 9: Install Required Python Packages
Odoo depends on several Python packages listed in the require file
located in the ‘odoo18’ directory. To install these packages, execute
the following command in the terminal.
pip install -r requirements.txt
If no errors occur, you can use the following command to verify that
all the dependencies listed in requirements.txt have been
successfully installed.
pip list

Enterprise
If you encounter any errors, open the requirements.txt file and install
each dependency individually using the following command.
pip install requirement_name
Example 1:
Example 2:

Enterprise
In most cases, when installing packages listed twice, only one needs
to be installed. So, if one fails to install, it usually isn’t an issue.
Additionally, if prerequisites defined with sys_platform as 'win32' fail
to install, you can skip them. If errors arise while installing the
package "psycopg2==2.9.2 ; sys_platform != 'win32' and
python_version <= '3.10' or psycopg2==2.9.5 ; python_version > '3.10'
or sys_platform == 'win32'", use the following command to install an
alternative package instead.
pip install psycopg2-binary

Enterprise
Step 10: Create the odoo.conf File in the odoo18 Directory
To create the configuration file, right-click the Odoo18 directory and
select New -> File -> odoo.conf. After creating the odoo.conf file, insert
the following block of code, and make sure to update the
db_password field with the password you set for the Odoo18
database user in the previous step.
[options]
admin_passwd = admin
db_host = localhost
db_port = 5432
db_user = odoo18
db_password = your_password
addons_path = /home/user/odoo18/addons
xmlrpc_port = 8018

Enterprise
Additionally, update the addons_path value with the actual path to
the Odoo18 addons directory. You can obtain this path by navigating
to the addons directory and pressing Ctrl + Shift + C. This will copy the
current directory path, which you can then replace in the
addons_path field. If you create a new directory for your custom
modules, be sure to include its path in the addons_path, separated by
commas.
eg: addons_path = /home/user/odoo/addons,
/home/user/odoo/custom_addons

Enterprise
Step 11: Add Python Interpreter
To configure a Python interpreter, navigate to Settings -> Project:
odoo18 -> Python Interpreter.

Enterprise
When you open the specified window, if the interpreter (Python 3.12
from the odoo18 virtual environment) is already configured, no
changes are needed. Otherwise, choose the Add Interpreter option
and proceed with the following selections.

Enterprise
Step 12: Configure the Project in PyCharm
To set up the project configuration, click Edit Configurations under
current File.

Enterprise
When the dialogue box appears, click the "+" button and choose
Python from the list. Then, fill in the fields as shown in the image
below.

Enterprise
Step 13: Test Run Odoo 18
The Odoo setup is complete. You can now test it by clicking the button
below to launch the project.

Enterprise
You can now test your setup by navigating to localhost:8018 in your
browser.
