Installation

There are a few ways you can install ScanCode.

  • Recommended standard install for everyone: Use a release download and install as an application
  • Advanced installation options:
  • pip install a Python PyPI package
  • from source code using a git clone
  • using Docker

Prerequisites

Before installing ScanCode make sure you have installed these prerequisites. The main one is to have Python installed version 3.6, 3.7, 3.8 or 3.9.

  • For Linux(Ubuntu): sudo apt install python3.6-dev bzip2 xz-utils zlib1g libxml2-dev libxslt1-dev
  • For MacOS: Install Python 3.x from https://www.python.org/
  • For Windows: Install Python 3.x from https://www.python.org/ using the 64 bits amd64 variant
  • For FreeBSD: (this needs to be documented)

Refer Prerequisites for detailed information on all different operating systems and Python versions.

Use a release download and install as an application

  • Download and extract the latest ScanCode release from https://github.com/nexB/scancode-toolkit/releases/

  • Open a terminal window (or command prompt on Windows) and then cd to the extracted ScanCode directory.

  • Run this command to self-configure and display the initial command line help:

    • Linux/Mac : ./scancode --help
    • Windows : scancode --help

Advanced installation: pip install a Python PyPI package

  • Create a virtual environment for Python 3.x and activate it:

    virtualenv -p python3 venv-scancode && source venv-scancode/bin/activate

  • Run pip install scancode-toolkit[full]

Note that the [full] extra option is required to get a working installation except in some advanced use cases.

Advanced installation: using Docker

  • Download the Source Code as an archive from the GitHub releases and unzip it, or via git clone.

  • Build the docker image from the scancode-toolkit directory:

    docker build -t scancode-toolkit .

  • Mount current working directory and run a scan the mounted folder:

    docker run -v $PWD/:/project scancode-toolkit -clpeui --json-pp /project/result.json /project

Note that the parameters before scancode-toolkit are used by docker and those after will be forwarded to scancode.

Advanced installation: from source code using a git clone

  • Download the Source Code or Use Git Clone:

    git clone https://github.com/nexB/scancode-toolkit.git
cd scancode-toolkit

  • Run the configure script for development usage:

    • On Linux/Mac: ./configure --dev
    • On Windows: configure --dev

If this displays the help text, you are all set to start using ScanCode.
