             spaCy is compatible with 64-bit CPython 2.6+/3.3+ and runs on Unix/Linux,

+            OS X and Windows. The latest spaCy releases are currently only available as source packages over #[+a("https://pypy.python.org/pypi/spacy") pip]. Installaton requires a working build environment. See notes on #[a(href="/docs#install-source-ubuntu") Ubuntu],

-            to avoid modifying system state:

-            python -m pip install -U pip virtualenv

-            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.
