You did not actually state what "the error" is. One of the most common 
problems on Windows is that it does not come with a compiler, you must 
install one. This link provides a MSVC compiler compatible with python 
2.7 (PyPy and CPython)

Are you sure you are using the pip from PyPy? Once you unzip the file 
you downloaded, you should open a DOS terminal, and execute

path\to\pypy-xxx/bin/pypy -m ensurepip
path\to\pypy-xxx/bin/pip install cython numpy
