MCEdit is an open-source, BSD-licenced world editor for the viral indie hit Minecraft. For downloads and update info, visit the official website at www.mcedit.net. The rest of this file is intended for computer programmers and Linux users.

MCEdit is written in Python using a variety of open source modules. When developing it is recommended to use virtualenv to keep dependencies sane and for easy deployment. You'll need Python 2.7 and easy_install/pip at a minimum before getting started. This quick guide assumes a unix-y OS.

Clone MCEdit:

git clone --recursive https://github.com/mcedit/mcedit

Or, if you've already cloned MCEdit in the past and need to update, go to the existing source folder:

git pull --recurse-submodules

Optionally (but highly recommended), setup and activate virtualenv. virtualenv will simplify development by creating an isolated and barebones Python environment. Anything you install while virtualenv is active won't affect your system-wide Python installation, for example.

cd mcedit
easy_install virtualenv
virtualenv ENV
. ENV/bin/activate

Install various dependencies. This may take a bit (especially numpy). If installing pygame errors, try installing from a binary packages or following one of the guides from that page to install from source. On Windows, easy_install is preferred because it installs prebuilt binary packages. On Linux and Mac OS X, you may want to use pip install instead.

easy_install PyOpenGL
easy_install numpy
easy_install pygame
easy_install pyyaml

Ubuntu Linux users can install the following packages via apt-get to grab all the dependencies easily and install them into the system python. This also downloads all libraries required to build these modules using pip install

apt-get install python-opengl python-pygame python-yaml python-numpy

You should now be able to run MCEdit with python mcedit.py assuming you've installed all the dependencies correctly.
