Chapter 2: Development Environment Set-up

There are multiple ways to install Odoo depending on the intended use case.

This document attempts to describe the installation options for an internal Odoo R&D developer. We assume that you are installing your development environment on a standard Odoo laptop with Linux Mint installed and up-to-date. At the time of writing, we are using a vanilla Linux Mint 20 (Ubuntu 20.04) as a starting point.

If you are using another environment, you can refer to Source Install.

Fetch the sources & configure git

Install and configure git

The very first step of the installation process is to install the git version control system because the Odoo source code is managed on GitHub. Once installed, you can set your name and email:

$ sudo apt install git
$ git config --global "Your full name"
$ git config --global ""

Configure GitHub

To fetch the sources and contribute to Odoo’s development you will need a GitHub account. We recommend using your trigram (xyz) followed by ‘-odoo’ as your username: ‘xyz-odoo’. If you prefer, you can also use your personal GitHub account.

The easiest way to authenticate with GitHub is to use an SSH connection. Using the SSH authentication will allow you to connect to GitHub without supplying your username and password every time.

The following instructions are based on the official GitHub documentation.

Here is a step-by-step procedure:

  • Generate a new SSH key, add it to the ssh-agent and copy the SSH key to your clipboard.

    $ ssh-keygen -t ed25519 -C ""
    $ ssh-add ~/.ssh/id_ed25519
    $ sudo apt-get install xclip
    $ xclip -sel clip < ~/.ssh/

In Github:

  • In the upper-right corner of any page, click your profile photo, then click Settings

  • In the user settings sidebar, click SSH and GPG keys.

  • Click New SSH key or Add SSH key.

  • In the “Title” field, add a descriptive label for the new key.

  • Paste your key into the “Key” field.

  • Click Add SSH key.

Fetch the sources

All the Odoo sources will be located in $HOME/src/

$ mkdir -p $HOME/src
$ cd $HOME/src
$ git clone
$ git clone


Cloning the repositories will take a while, enjoy a cup of coffee while you wait.


You may need to ask your manager for read rights to fetch the enterprise repository.

Configure development repository

To contribute to Odoo’s development you will need to fork the repository, create a branch containing your code in the fork and submit a Pull Request to the Odoo repository.

If you are lucky enough to work at Odoo, the forks already exist. They are called odoo-dev/odoo and odoo-dev/enterprise.

$ cd  $HOME/src/odoo
$ git remote add odoo-dev #add odoo-dev as a new remote
$ git remote rename origin odoo #change the name of origin (the odoo repository) to odoo
$ git remote set-url --push odoo no_push #remove the possibility to push to odoo (you can only push to odoo-dev)

$ cd  $HOME/src/enterprise
$ git remote add enterprise-dev
$ git remote rename origin enterprise
$ git remote set-url --push enterprise no_push

Useful git commands

Here are some useful git commands for your day-to-day work.

  • Change branch: When you change branches, both repositories (odoo and enterprise) must be synchronized, i.e. both need to be in the same branch.

    $ cd $HOME/src/odoo
    $ git checkout 14.0
    $ cd $HOME/src/enterprise
    $ git checkout 14.0
  • Fetch and rebase:

    $ cd $HOME/src/odoo
    $ git fetch --all --prune
    $ git rebase --autostash odoo/14.0
    $ cd $HOME/src/enterprise
    $ git fetch --all --prune
    $ git rebase --autostash enterprise/14.0

Install the dependencies


Odoo requires Python 3.6 or later, if your computer is up-to-date you should already be at this version or higher.

You can check your Python version with:

$ python3 --version

Install pip3 and libraries

For libraries using native code, installation of development tools and native dependencies is required before installing the Python dependencies of Odoo.

$ sudo apt install python3-pip python3-dev libxml2-dev libxslt1-dev libldap2-dev libsasl2-dev libssl-dev libpq-dev libjpeg-dev

Install odoo requirements

$ cd $HOME/src/odoo
$ pip3 install -r requirements.txt

Install wkhtmltopdf

wkhtmltopdf is a library to render HTML into PDF. Odoo uses it to create PDF reports. wkhtmltopdf is not installed through pip and must be installed manually in version 0.12.5 to support headers and footers.

$ cd /tmp/
$ sudo wget
$ sudo gdebi --n wkhtmltox_0.12.5-1.focal_amd64.deb
$ sudo ln -s /usr/local/bin/wkhtmltopdf /usr/bin
$ sudo ln -s /usr/local/bin/wkhtmltoimage /usr/bin

Right-to-left interface support

In order to support right-to-left (RTL) languages, we need rtlcss to convert the CSS files:

$ sudo apt-get install nodejs npm
$ sudo npm install -g rtlcss

Install PostgreSQL

As seen in Chapter 1: Architecture Overview, Odoo uses PostgreSQL as a RDBMS. In the context of a development machine, the easiest approach is to install it locally. Then we can create a PostgreSQL user corresponding to our current user:

$ sudo apt install postgresql postgresql-client
$ sudo -u postgres createuser -s $USER

Some useful SQL commands:

$ createdb $DB_NAME #Create a database
$ dropdb $DB_NAME #Drop a database

$ psql $DB_NAME #Connect to a database
    \l #List all the available databases
    \dt #List all the tables of the $DB_NAME database
    \d $TABLE_NAME #Show the structure of the table $TABLE_NAME
    \q #Quit the psql environment (ctrl + d)

Run the server

Running odoo-bin

Once all dependencies are set up, Odoo can be launched by running odoo-bin, the command-line interface of the server.

$ cd $HOME/src/odoo/
$ ./odoo-bin --addons-path="addons/,../enterprise/" -d rd-demo

There are multiple command-line arguments that you can use to configure the server. In this training you will only need some of them.


The database that is going to be used.


A comma-separated list of directories in which modules are stored. These directories are scanned for modules.


Prevents the worker from using more than <limit> CPU seconds for each request.


Prevents the worker from taking longer than <limit> seconds to process a request.

The last two can be used to prevent the worker from being killed when debugging the source code.


You may face an error similar to AttributeError: module '$MODULE_NAME' has no attribute '$ATTRIBUTE'

In this case you may need to re-install the module with $ pip install --upgrade --force-reinstall $MODULE_NAME

If this error occurs with more than one module then you may need to re-install all the requirements with $ pip3 install --upgrade --force-reinstall -r requirements.txt

You can also clear the python cache to solve the issue

$ cd $HOME/.local/lib/python3.8/site-packages/
$ find -name '*.pyc' -type f -delete

Log in to Odoo

Open http://localhost:8069/ on your browser. We recommend you use: FirefoxChrome (Chromium the open source equivalent) or any other browser with development tools.

To log in as the administrator user, you can use the following credentials:

  • email = admin

  • password = admin

The developer mode

The Developer or Debug Mode gives you access to additional (advanced) tools.

This is useful for training and we assume that the user is in developer mode for the rest of the tutorials.

To activate the developer or debug mode you can follow the steps here.

Extra tools

Code Editor

If you are working at Odoo, many of your colleagues are using VSCode (VSCodium the open source equivalent), Sublime TextAtom or PyCharm. However you are free to choose your preferred editor.

Don’t forget to configure your linters correctly. Using a linter can help you by showing syntax and semantic warnings or errors. Odoo source code tries to respect Python and JavaScript standards, but some of them can be ignored.

For Python, we use PEP8 with these options ignored:

  • E501: line too long

  • E301: expected 1 blank line, found 0

  • E302: expected 2 blank lines, found 1

For JavaScript, we use ESLint and you can find a configuration file example here.

If you do not know how to set up a linter:

Administrator tools for PostgreSQL

You can manage your PostgreSQL databases using the command line as demonstrated earlier or using a GUI application such as pgAdmin or DBeaver.

To connect the GUI application to your database we recommend you connect using the Unix socket.

  • Host name/address = /var/run/postgresql

  • Port = 5432

  • Username = $USER

Python Debugging

When facing a bug or trying to understand how the code works, simply printing things out can go a long way, but a proper debugger can save a lot of time.

You can use a classic Python library debugger (pdbpudb or ipdb) or you can use your editor’s debugger. To avoid difficult configurations in the beginning, it is easier if you use a library debugger.

In the following example we use ipdb, but the process is similar with other libraries.

  • Install the library:

    pip3 install ipdb
  • Trigger (breakpoint):

    import ipdb; ipdb.set_trace()


       def copy(self, default=None):
           import ipdb; ipdb.set_trace()
           chosen_name = default.get('name') if default else ''
           new_name = chosen_name or _('%s (copy)') %
           default = dict(default or {}, name=new_name)
           return super(Partner, self).copy(default)

Here is a list of commands:


Without an argument, print the list of available commands. With a command as an argument, print help about that command.


The value of the expression is pretty-printed using the pprint module.


Print a stack trace, with the most recent frame at the bottom.


Move the current frame one level down in the stack trace (to a newer frame).


Move the current frame one level up in the stack trace (to an older frame).


Continue the execution until the next line in the current function is reached or it returns.


Continue the execution and only stop when a breakpoint is encountered.


Execute the current line, stop at the first possible occasion (either in a function that is called or on the next line in the current function).


Quit the debugger. The program being executed is aborted.


To avoid killing the worker when debugging, you can add these arguments when launching the server: --limit-time-cpu=9999 --limit-time-real=9999 Another solution is to add them directly in the ~/.odoorc file:

$ cat ~/.odoorc
limit_time_cpu = 9999
limit_time_real = 9999

Now that your server is running, it’s time to start writing your own application!
