Not able to open an instance of google chrome with DevTools about pychromedevtools

[Forest-Dewberry]

I found the solution. First of all, the fact that my program "stalled" in my terminal is not a problem - it simply means that the chrome process is ongoing. in order to resolve this apparent issue, which is more like a preference, I elected to open a different terminal, but I could have used:

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222 --user-data-dir=remote-profile&

The ampersand causes the program to run in the background.

Secondly, I had a problem executing:

>>> import PyChromeDevTools
>>> chrome =  PyChromeDevTools.ChromeInterface()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/site-packages/PyChromeDevTools-0.1-py3.6.egg/PyChromeDevTools/__init__.py", line 43, in __init__
  File "/usr/local/lib/python3.6/site-packages/PyChromeDevTools-0.1-py3.6.egg/PyChromeDevTools/__init__.py", line 54, in connect
AttributeError: module 'websocket' has no attribute 'create_connection'

The cause of this error is that I had installed the wrong dependency with pip. Running "pip3 list" (I have two separate pip installations, one for python2.7 and one for python3, with symlinks pip and pip3 accordingly; if you only have python3 and use only one installation of pip, you're fine, don't worry about this) I got:

I uninstalled websocket then installed websocket-client, with this result:
