MCEdit 2.0 is the next version of MCEdit, the World Editor for Minecraft. MCEdit allows you to edit every aspect of a Minecraft world, and to import and export .schematic files created by many programs including WorldEdit and the original MCEdit 1.x. It is free to use and licensed under the BSD license.
MCEdit 2.0's development is in the alpha stage. Many features may be buggy or missing. To download MCEdit 2.0 anyway, head over to http://www.mcedit.net/
The rest of this file is of interest to programmers only.
This guide is written with Windows developers in mind. Linux / OS X developers can read how to install below. Windows developers are assumed to be using a unix shell such as the GIT Bash included with the Windows distribution of Git.
- Install Python for Windows v2.7.9. Edit your PATH environment variable (or your
.bashrc) to have both the
python27\scriptsfolders. (by default,
- Install Microsoft Visual C++ Compiler for Python 2.7. This is not needed if you already have MSVC 2008 (Visual Studio 9.0) or the Windows SDK 7.0 installed, but you probably don't so install it anyway.
- Install virtualenv:
pip install virtualenv(pip is now included with recent versions of Python)
- Update to the latest setuptools to make sure Cython modules compile:
pip install -U setuptools
- Create a local clone of the MCEdit sources:
git clone https://github.com/mcedit/mcedit2
- Using the
bashshell, change directory to the local clone:
- Create a virtualenv using
- Activate the virtualenv using
A virtualenv is created in the local clone directory to keep MCEdit's required libraries isolated from those installed in the systemwide Python folder. This prevents unpleasant surprises when you update a library for another project and later find it isn't compatible with MCEdit.
Now, install the required libraries.
easy_install is able to install binary installer packages into a virtualenv. Download each of the following and run
easy_install <module>.exe while the virtualenv is active. Binary packages for the following are available at Chris Gohlke's page. Download the versions for Python 2.7, and make sure to download the
win32 versions if you installed the 32-bit Python (the default) or the
win-amd64 versions for 64-bit Python.
- pyopengl (be sure to grab
- pywin32 (for registry access)
- cython (for building
- ipython (for debugging)
- pygments (required by IPython)
- numpy **
Also use pip to install these libraries:
pip install arrow- a date/time class with nice text formatting.
pip install pyzmq- Gohlke's pyzmq builds don't work on Windows XP
**Note that Gohlke's numpy builds use the Intel Math Kernel Library (MKL) which requires a license to use. If you have not purchased an MKL license (it's expensive) then you DO NOT HAVE PERMISSION TO DISTRIBUTE APPS built with it. I didn't notice any better performance with MKL regardless.
An alternative is to install the official builds of numpy from the SourceForge Downloads
but 64-bit builds are not provided. If you need a 64-bit build of numpy that does not include MKL, you will need to
build it yourself. Also, the official builds are packed into a "superpack" installer which easy_install chokes on.
Just open the installer in an archiving program like 7-zip and extract the SSE3 installer,
Another alternative to downloading all of the above is to download all the packages
from my dropbox folder. Note that the
64-bit numpy package is one I built myself, with several facilities (LAPACK, BLAS etc) disabled because I couldn't
be bothered to find out why MSVC 64-bit chokes on them. MCEdit seems to run fine without them. Install
python-2.7.9.msi first, then install MSVC++ for Python,
then virtualenv, and create and activate a virtualenv as above. Install each of the .exe files using
and make sure to
pip install arrow too.
Once all of the requirements are met, install MCEdit itself into the virtualenv. This will build
mceditlib are on the pythonpath, and also create an
mcedit2 script making it easy to launch
python setup.py develop
All that's left is to see if the app launches.
As a bonus, you can use the
-debug flag to enable the Debug menu and a few extra widgets.
Linux/OS X (not tested fully)
cd (Your mcedit2 location) virtualenv ENV . ENV/bin/activate pip install -r requirements.txt python setup.py develop mcedit2
If your distro packages python3 as the default version of python instead of python2, you will probably want to set your virtualenv to use python2, i.e.
virtualenv -p python2 ENV
If you get a
Library not loaded: libpyside-python220.127.116.11.dylib error, try running
pyside_postinstall.py -install to fix this.
If after that, you get a
Library not loaded: /usr/local/lib/QtGui.framework/Versions/4/QtGui error after that, try installing
qt using a package manager like Homebrew or apt-get or similar equivalent on your distribution. You may also need
python-dev packages installed before the commands above will work.
brew install qt etc. or:
sudo apt-get install qt-sdk sudo apt-get install libxslt-dev sudo apt-get install python-dev
