Downloading and Installing
For moin2, there is currently no packaged download available, so you have to get it from the repository. You can use one of two repository URLs and either use Mercurial to keep a constantly updated copy of the code or download an archive of the files in tar.gz format:
Using Mercurial to clone one of the repositories:
hg clone http://hg.moinmo.in/moin/2.0 moin-2.0 OR hg clone http://bitbucket.org/thomaswaldmann/moin-2.0 moin-2.0
Now make sure your work directory is using the default branch:
hg up -C default
Alternatively, visit http://hg.moinmo.in/moin/2.0 with your web browser and download the archive (usually for the "default" branch) and unpack it.
Before you can run moin, you need to install it:
Using your standard Python install or a virtualenv directory
Please make sure you have virtualenv installed, it includes pip.
If you just want to run moin in-place in your mercurial working directory with your normal system installation of Python, run the following command from your mercurial moin2 working directory. You should not run this as an administrator or root user; use your standard user account:
./quickinstall # for Linux or other POSIX OSes # or quickinstall.bat # for Windows
This will use virtualenv to create a directory env/ within the current directory, create a virtual environment for MoinMoin and then install moin2 including all dependencies into that directory. pip will automatically fetch all dependencies from PyPI and install them, so this may take a while. It will also compile the translations (*.po files) to binary *.mo files.
Please review the output of the quickinstall script, and check whether there were fatal errors.
If you have a bad network connection that makes the downloads fail, you can try to do the steps in quickinstall manually.
Further, the quickinstall script will create a moin script for your platform which you can use for starting the built-in server or invoke moin script commands.
After you activated the virtual environment, the built-in server script, which is named moin, will be in the standard PATH, so you can just run the command moin on the command line.
Note: in this special mode, it won't copy the MoinMoin code to the env/ directory, it will run everything from your work dir, so you can modify code and directly try it out. You only need to do this installation procedure once.
Using a different Python or a different virtualenv directory
For example, if you want to use PyPy and want to name the virtualenv directory env-pypy, use:
# for linux DIR=env-pypy PYTHON=/opt/pypy/bin/pypy
That way, you can test with different versions of Python in different virtualenv directories within your moin2 workdir.
Activating the virtual env
IMPORTANT: you always need to activate the virtual environment before running anything that executes moin code! Otherwise it won't find the moin command, nor the moin code nor the libraries it needs. Also, if you want to install additional software into the virtual environment, activate it before running pip!:
source env/bin/activate # for linux (or other posix OSes) # or env\Scripts\activate.bat # for windows
As you have activated the virtual env now, the moin command should be in your path now, so you can invoke it using "moin".
Letting moin find the wiki configuration
moin needs to find the wiki configuration. If you want it to run in the most simple way without giving parameters to the moin command, it is easiest if you are in the same directory as the configuration files, e.g. wikiconfig.py.
If you are working from a repository workdir, this is the top level directory and there is already a ready-to-use wikiconfig.py.
In case you want to just give the configuration file location, make sure you use an absolute path. moin will try to find its configuration in this order:
- command line argument --config /path/to/wikiconfig.py
- environment variable MOINCFG=/path/to/wikiconfig.py
- current directory, file wikiconfig_local.py
- current directory, file wikiconfig.py
Initializing index and/or storage
If you have an existing storage AND a valid index (for this storage’s content and for this moin version), you can skip this section.
If you start from scratch, ie no storage and no index created yet, you need to create an empty storage and an empty index:
# create storage and index: moin index-create -s -i
Loading some items
If you don't want to have a completely empty wiki, you can optionally load some example items into the storage like this:
# load some example items: moin load --file contrib/serialized/items.moin
Building the index
If you have some items in your storage, but no index built yet, you need to build an index:
For some image processing functions that MoinMoin uses like resizing and rotating, you need PIL, which is the Python Imaging Library.
Windows users who want to install PIL should skip the remainder of this section and read Troubleshooting -- PIL Installation Under Windows below.
If you install PIL with pip, then pip will try to find a jpeg support library and associated development headers on your system and if you do not have them, there will be no jpeg support in PIL. So, if you want jpeg support, make sure you have the jpeg libs/headers:
# install jpeg library and development headers: sudo apt-get install libjpeg62-dev # Ubuntu / Debian-based yum install libjpeg-turbo-devel # Fedora / Redhat-based
Now activate your virtual environment and install PIL into it:
pip install pil # for Linux or other POSIX OSes
Now and then, PyPi might be down or unreachable.
There are mirrors b.pypi.python.org, c.pypi.python.org, d.pypi.python.org you can use in such cases. You just need to tell pip to do so:
# put this into ~/.pip/pip.conf [global] index-url = http://c.pypi.python.org/simple
In case that doesn't work either, try our mini pypi that should have all packages you need for moin:
# put this into ~/.pip/pip.conf [global] index-url = http://pypi.moinmo.in/simple
Bad Network Connection
If you have a poor or limited network connection, you may run into trouble with the commands issued by the quickinstall script. You may see tracebacks from pip, timeout errors, etc. See the output of the quickinstall script.
If this is the case, try it manually:
# enter your virtual environment: source env/bin/activate # confirm the problems by running: pip install -e .
Now install each package into your virtual env manually:
Find the required packages by looking at "install_requires" within setup.py.
Download each required package from http://pypi.python.org/
Install each of them individually:
pip install package.tar
Now try again:
pip install -e .
Repeat these steps until you don't see fatal errors.
PIL Installation Under Windows
PIL version 1.1.7 does not install correctly via "pip install pil" on Windows. Some users have had success using "pip install pillow", a fork of PIL fixing a packaging issue. Other users have resorted to installing PIL 1.1.6 in the main Python directory using the Windows installers available at http://www.pythonware.com/products/pil/
