pip install --upgrade pip

pip install virtualenv

cd /tmp/

virtualenv --distribute --no-site-packages  test

vi /tmp/test/t.py

import tornado.ioloop
import tornado.web


class MainHandler(tornado.web.RequestHandler):
    def get(self):
        self.write("Hello, world")


application = tornado.web.Application([
    (r"/", MainHandler),
])


if __name__ == "__main__":
    application.listen(8888)
    tornado.ioloop.IOLoop.instance().start()
