First run problem Python2.7 - unexpected keyword argument 'syntax'

I'm getting the following error running the ./example.py script and also interactively on import pychromecast

Traceback (most recent call last):

I'm using

macOS Sierra
Python 2.7.11
pip 9.0.1 from /usr/local/lib/python2.7/site-packages (python 2.7)
(and all requirements are satisfied)

Any ideas short of python3?

Looks like #47, but you have latest pip.

It's working for me with:

• macOS Sierra
• Python 2.7.12
• pip 9.0.1 from /usr/local/lib/python2.7/site-packages (python 2.7)

Try moving example.py to a completely different directory, and running it from there. It's may be there's some import confusion between the installed pychromecast and the pychromecast directory in the current working directory.

Have you also installed protobuf with homebrew? Have a look at this.

Stumbled across #130 and #47. Ended up sticking with Python3 (was simply testing Python 2.7) but did see https://github.com/skorokithakis/catt which documents that catt version 0.5.6 has python 2 support in case anyone really needs Python 2.7 support.

Pychromecast is Python 3 only since quite some time
