Build from Source

Prerequisites

Before starting, ensure you have the following installed:

• Git
• Python 3.11.x
• VirtualEnv (for macOS and Linux)
• Node.js
• pnpm

Downloading source

This guide assumes you want to use Git to clone the project into a development directory; if you prefer to download the source from GitHub as a zip, you can do that instead.

1. Fork the relevant rotki branch into your own GitHub account.
2. Open a terminal (Command Prompt / PowerShell prompt) in your root development directory (the parent directory of where you will place your rotki development directory).
3. Clone your forked project into the local directory where you want to build rotki (e.g., if you forked the rotki/develop branch, you might clone into c:\dev\rotki-develop).

In your local rotki development directory, you should have all the files as they appear in the GitHub page for the rotki branch you chose to download/clone.

Backend setup for Linux

Set Up Python Environment

Create a new virtual environment with Python 3.11 to install all the Python dependencies. If you don't have mkvirtualenv, check how to get it depending on your distribution. Here is a guide for Ubuntu and here is one for ArchLinux:

mkvirtualenv rotki -p /usr/bin/python3.11

Then install all the Python requirements:

pip install -r requirements.txt
# Developer requirements
pip install -r requirements_dev.txt
pip install -e .

Follow the Frontend setup to complete the setup.

Backend setup for macOS

The tl;dr version is:

• Use a virtual environment with Python 3.11.x.
• Confirm pip (pip3) is installed correctly and up to date.

Install Homebrew first if not installed yet.

Set Up Python Environment

pip3 install virtualenv virtualenvwrapper

Add the following to your shell startup file (e.g. .bashrc, .bash_profile, or .zshrc):

# Virtualenvwrapper settings:
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/rotki_dev
export VIRTUALENVWRAPPER_PYTHON=/Library/Frameworks/Python.framework/Versions/3.11/bin/python3
export VIRTUALENVWRAPPER_VIRTUALENV=/Library/Frameworks/Python.framework/Versions/3.11/bin/virtualenv
source /Library/Frameworks/Python.framework/Versions/3.11/bin/virtualenvwrapper.sh

Reload the shell startup file and activate the Python virtual environment:

source ~/.bash_profile
workon rotki

Install all the requirements:

pip3 install --upgrade pip
pip3 install -r requirements.txt
# Developer requirements
pip3 install -r requirements_dev.txt
pip3 install -e .

Follow the Frontend setup to complete the setup.

Backend setup for Windows

Dependencies

1. Install Python 3.11 (64-bit version for 64-bit Windows).
2. Ensure Python is in the Path variable. If not:
   • Go to Control Panel -> System -> Advanced system settings -> Advanced (tab) -> Environment Variables...
   • Under "System Variables," open the "Path" variable and ensure both the root Python directory and the Scripts subdirectory are included.
   • If not, add them by clicking "New" and then "Browse" and locating the correct directories.
   • By default, the Windows MSI installer places Python in the C:\Users\<username>\AppData\Local\Programs\ directory.
3. Test Python installation by opening a command prompt and typing python. The Python CLI should run, showing the Python version you installed. Press CTRL+Z, then Enter to exit.

   Note: In newer versions of Windows, typing "python" may open the Windows Store. Fix this by opening "App execution aliases" (search for it via Windows Search) and toggling off the aliases for python.exe and python3.exe.

4. Ensure you have pip installed. Check by typing pip -V into a command prompt.
5. Ensure you have the latest version of pip:

   pip install --upgrade pip

6. Using pip, install virtualenv and virtualenvwrapper-win:

   pip install virtualenv virtualenvwrapper-win

7. Install Microsoft Visual Studio build tools with the "Desktop development with C++" workload.

Set Up Python Environment

1. Open a terminal (Command Prompt / PowerShell prompt) in your root development directory.
2. Create a new virtual environment:

   mkvirtualenv rotki-develop

3. Ensure you are in the directory where you downloaded/cloned the rotki source and bind the virtualenv to the directory:

   setprojectdir .

4. Install Python requirements:

   pip install -r requirements.txt
   # Developer requirements
   pip install -r requirements_dev.txt
   pip install -e .

5. Download miniupnpc for Windows and copy miniupnpc.dll to your virtual environment's Lib > site-packages directory. Locate this directory using the command:

   pip show cryptography

Then follow the Frontend setup to complete the setup.

To ensure rotki backend works, try starting it:

python -m rotkehlchen

This should greet you with the message:

rotki REST API server is running at: 127.0.0.1:5042

Frontend setup

Make sure you have Node.js installed. You can check https://nodejs.org/en/download/package-manager for more information.

Installing PNPM

Check the required PNPM version in frontend/package.json under the packageManager key. For example, if it says:

{
  "packageManager": "pnpm@9.9.0"
}

It means you need to have pnpm version 9.9.0 installed. To check the current version of pnpm you have, run:

pnpm --version

If you are on an older version of pnpm, you can install it by:

pnpm install -g pnpm@9.9.0
# or if you don't have it installed you can
npm install -g pnpm@9.9.0

The first time you run pnpm, you need to run:

pnpm setup

Install Node.js Dependencies

cd frontend
pnpm install --frozen-lockfile

If you modified the @rotki/common package, you might need to rebuild it:

pnpm run --filter @rotki/common build

Running rotki

Start the application from the frontend directory:

pnpm run dev

For non-Electron development:

pnpm run dev:web

Packaging

To package the application for your platform, you need to run the packaging script. To do so, make sure that packaging and requests are installed in your virtual environment:

pip3 install packaging requests

# Use this command if you are in Linux or macOS
./package.py --build full

# Use this command if you are in Windows
python .\package.py --build full

Nix

You can use the Nix package manager to start rotki development. Create flake.nix in the root of the project and copy the following into it:

{
  description = "rotki project with virtualenv";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-23.11";
    nixpkgs-unstable.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    flake-utils.url = "github:numtide/flake-utils";
  };

  outputs = { self, nixpkgs, flake-utils, ... }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        pkgs = nixpkgs.legacyPackages.${system};

        python311 = pkgs.python311;
        nodejsWithPython311 = pkgs.nodejs.override { python3 = python311; };
        nodePackages = pkgs.nodePackages.override { nodejs = nodejsWithPython311; };
        pnpmWithPython311 = nodePackages.pnpm;

        myPythonEnv = pkgs.mkShell {
          name = "my-python-env";
          buildInputs = [
            pkgs.gcc
            pkgs.stdenv.cc.cc.lib
            pkgs.bash
            pkgs.lzma
            pkgs.git
            pnpmWithPython311
            pkgs.python311
            pkgs.python311Packages.virtualenv
            pkgs.python311Packages.pip
          ];

          shellHook = ''
            ${pkgs.pkgs.python311Packages.virtualenv}/bin/virtualenv --no-setuptools --no-wheel .venv
            source .venv/bin/activate
            export RUFF_PATH=${pkgs.ruff}/bin/ruff
            export PYTHONPATH=.venv/${pkgs.python311.sitePackages}/:$PYTHONPATH
            export LD_LIBRARY_PATH=${pkgs.stdenv.cc.cc.lib}/lib:$LD_LIBRARY_PATH
            pip install setuptools
            pip install -r ${./requirements.txt}
            pip install -r ${./requirements_dev.txt}
            pip install -r ${./requirements_lint.txt}
          '';
        };
      in
      {
        devShell = myPythonEnv;
      }
    );
}

Then execute the following command to let Nix build the entire environment where you can start rotki development:

nix develop

From this point onward, start backend/frontend:

cd frontend
pnpm run dev:web

Docker

To build Docker image from source using Dockerfile:

docker build -t rotki .

Troubleshooting

anyapi-ms-win-crt-runtime missing

If you get anyapi-ms-win-crt-runtime-l1-1-0.dll is missing error when running Python, follow this guide to resolve it.

Microsoft Visual C++ 14.0 is required

If you get:

building 'gevent.libev.corecext' extension
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": https://visualstudio.microsoft.com/downloads/

Then go here and get the Microsoft Visual Studio build tools and install them. The specific parts of the tools that need to be installed can be seen in this Stack Overflow answer.

You also need to add them to the path. The tools were probably installed here: C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\Common7\Tools Environment variable should be: VS140COMNTOOLS
