Installing Spidy is easy since it doesn’t have external dependencies. This page explains how.
Install pip (Python package manager): https://pypi.python.org/pypi/pip
Now install Spidy using pip:
pip install Spidy
Installing Spidy for Windows is a bit complicated, since Python is not part of Windows distribution.
In command prompt, change directory to Spidy’s folder and enter:
python setup.py bdist_wininst
The command will produce Windows installer in spidy/dist folder, e.g.: dist/Spidy-0.1.win32. Now simply run the installer and enjoy the process.
