Pyramid build error

[vacation...@gmail.com]

I am very new to Pyramid new as in I only heard of it a couple of days ago.
I installed it using pip and was creating my first app.  but I received the following error when I used the following command.
pserve development.ini
I am not sure what to do.  Any help and thanks in advanced.  I used the following guide.  
http://docs.pylonsproject.org/projects/pyramid/en/1.3-branch/narr/project.html#project-narr
I did not create an virtual environment.

Starting server in PID 30147.
Traceback (most recent call last):
  File "/usr/local/bin/pserve", line 9, in <module>
    load_entry_point('pyramid==1.8.3', 'console_scripts', 'pserve')()

The version of waitress is not in-line with a version that supports the listen attribute.

Please see http://docs.pylonsproject.org/projects/pyramid/en/latest/narr/install.html for installing Pyramid and it’s dependencies correctly, you most likely want a virtual environment so that you don’t run into issues with the distributions installed versions of packages.

Thanks Bert
I will go the virtual environment way.  I just wanted everything the same as it would be in production.

[Bert JW Regeer]

I would highly recommend also using a virtualenv in production for the same reason.

You are following documentation for an unsupported version of
Pyramid. See that little red button in the corner, "> Read the
latest version of this page"? Click it. You will have a much
better experience.
