Installing python support library on Rpi


#1

First post here, so I appologize if I am adding this to the wrong area.
I have been using OSMC since it’s inception and have had great success with it. Thank you @sam_nazarko. Anyway recently my Rpi performed the October update without any issues but today I discovered something odd that I am 100% certain was working prior to the update. Basically i have some python scripts that control some room lighting when I start a movie (using the cinemavision addon). These python scripts have worked flawlessly for about a year. Today when I attempted to run the scripts they were erroring out with the following error.

osmc@osmc:~/CV/Actions$ python MoviePause.py
Traceback (most recent call last):
File “MoviePause.py”, line 2, in
from websocket import create_connection
ImportError: No module named websocket

This was a surprise, like i said these scripts have been working for a while now without any issues.
To rectify the issue I attempted to install the missing websocket module and it too errored out.
I am hoping someone can help me to get me operational again.

osmc@osmc:~/CV/Actions$ pip install websocket

#2

Try:

sudo apt-get install python-websocket instead.

It’s trying to cross compile. If you really want to build from source.

sudo apt-get update
sudo apt-get install build-essential
export ARCH=arm
export CROSS_COMPILE=/usr/bin/

Cheers

Sam
