To use MongoEngine, you will need to download MongoDB and ensure it is running in an accessible location. You will also need PyMongo to use MongoEngine, but if you install MongoEngine using setuptools, then the dependencies will be handled for you.
MongoEngine is available on PyPI, so to use it you can use pip:
$ pip install mongoengine
Alternatively, if you don’t have setuptools installed, download it from PyPi and run
$ python setup.py install
To use the bleeding-edge version of MongoEngine, you can get the source from GitHub and install it as above:
$ git clone git://github.com/mongoengine/mongoengine $ cd mongoengine $ python setup.py install
