I am using Python 2.5 on Windows 7 (64bit).
I installed pycurl-7.15.5.1 (with win binaries) and tornado (using pip).
When I run the following hello world cod
from tornado web page (http://www.tornadoweb.org/)
Platforms: Tornado should run on any Unix-like platform, although for the best performance and scalability only Linux and BSD (including BSD derivatives like Mac OS X) are recommended.
I think it is not compatible with windows
Things similar with tornado can be achieve with twisted framework http://twistedmatrix.com which works under windows
