Install dark matter in a Python virtual environment

The dark matter code runs under Python 2 and 3. You need to create a virtual environment for the Python of your choice and then install the correct requirements:

Python 2

$ sudo pip install virtualenv
$ virtualenv --python=python2 env
$ . env/bin/activate
$ pip install dark-matter
$ cd dark-matter
$ pip install -r requirements-2.txt

Python 3

$ sudo pip install virtualenv
$ virtualenv --python=python3 env
$ . env/bin/activate
$ pip install dark-matter
$ cd dark-matter
$ pip install -r requirements-3.txt

Set PYTHONPATH

You may want to add the dark-matter directory (the one that was created above by git clone) to your PYTHONPATH.

Install a taxonomy database (optional)

See taxonomy.md for details.
