The most recent release is always available in the cheeseshop and can be installed using easy_install:
easy_install python-restclient
Alternatly, you can also install the development version from our Mercurial repository:
hg clone https://dev.e-engura.org/hg/python-restclient
cd python-restclient
sudo python setup.py install
Last command will install pthon-restclient as a package via setuptools. This will make it available in your python path. Alternately you can copy or symlink the simplecouchdb subdirectory into your site-packages directory or anywhere in your PYTHONPATH.
You could also get source from Bitbucket
hg clone https://benoitc@bitbucket.org/benoitc/python-restclient/
To use py-simplecouchdb you will need Python 2.5 or later.
