p With Python 2.7 or Python 3, using Linux or OSX, run:

pre.language-bash: code
  | $ pip install spacy
  | $ python -m spacy.en.download</code></pre>

p
  | The download command fetches and installs about 300mb of data, for
  | the parser model and word vectors, which it installs within the spacy.en
  | package directory.

  | If you're stuck using a server with an old version of Python, and you
  | don't have root access, I've prepared a bootstrap script to help you
  | compile a local Python install.  Run:

pre.language-bash: code
  | $ curl https://raw.githubusercontent.com/honnibal/spaCy/master/bootstrap_python_env.sh | bash && source .env/bin/activate

p
  | The other way to install the package is to clone the github repository,
  | and build it from source.  This installs an additional dependency,
  | Cython.  If you're using Python 2, I also recommend installing fabric
  | and fabtools &ndash; this is how I build the project.

pre.language-bash: code
  | $ git clone https://github.com/honnibal/spaCy.git
  | $ cd spaCy
  | $ virtualenv .env && source .env/bin/activate
  | $ export PYTHONPATH=`pwd`
  | $ pip install -r requirements.txt
  | $ python setup.py build_ext --inplace
  | $ python -m spacy.en.download
  | $ pip install pytest
  | $ py.test tests/

p
  | Python packaging is awkward at the best of times, and it's particularly tricky
  | with C extensions, built via Cython, requiring large data files.  So,
  | please report issues as you encounter them.
