Trying to install Tornado for first time (On EC2 Linux instance). I did
pip install tornado
and then tried running the hello world example: http://www.tornadoweb.org/en/stable/#hello-world
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(80)
tornado.ioloop.IOLoop.instance().start()
I then try:
python hello.py
but get:
Traceback (most recent call last): File "testing/tornado.py", line 1, in
import tornado.ioloop File "/opt/pdf_engine/testing/tornado.py", line 1, in
import tornado.ioloop ImportError: No module named ioloop
Don't name your file tornado.py
; it shadows the actual Tornado import. Name it something like what you used in your example, e.g. hello.py
Right now, your import tornado.ioloop
is trying to import the member ioloop
from your own file, because it's named tornado
and in the current directory which has the highest import precedence.
If you named your file tornado.py and rename it to another name,don't forget to remove tornado.pyc in your directory.
