Cannot get Twisted to work on a Mac

I am attempting to run the source code associated with the article at https://pawelmhm.github.io/python/websockets/2016/01/02/playing-with-websockets.html, but cannot get Twisted to work. I am using macOS High Sierra 10.13.5 and Python 3.6.4 (in a virtual environment).

To create the virtual environment I used: python3 -m venv venv . venv/bin/activate

where python3 is my system installed python 3.6.4: $ which python3 /Library/Frameworks/Python.framework/Versions/3.6/bin/python3

I tried installing twisted using pip:

$ pip install twisted

But I keep getting the error:

$ python server.py
Traceback (most recent call last):

    from twisted.web.static import File
ModuleNotFoundError: No module named 'twisted'

Search on the web resulted in no useful resolution and attempts to use either easy_install or brew did not work too. Any suggestions are appreciated.

Thank you @9769953, that resolved the issue!

If anyone else searches for this issue (and for my future reference!), use: python -m pip install twisted

I did have a virtual environment but apparently the python and pip combination was messing this up. Using python -m pip resolved the dependency issue.
