websocket_messaging incompatible in web2py 2.15.4?

[Martin Weissenboeck]

Some months ago I have written a test application for gluon/contrib/websocket_messaging.py and it worked very well. Now (after an update to 2.15.4) I tried it again and I got some errors.

I started with 

python /home/www-data/web2py/gluon/contrib/websocket_messaging.py -k mykey -p 8888 -s /etc/nginx/ssl/web2py.key -c /etc/nginx/ssl/web2py.crt

and I got the message, that gluon.contrib was not found.

I added the line 

sys.path.append('/home/www-data/web2py/')

before import gluon.contrib and this solved the problem. Maybe not the best solution, but it worked.

I tried it again and got:

pypyodbc.OdbcNoLibrary: 'ODBC Library is not found. Is LD_LIBRARY_PATH set?'

Is there anything new in 2.15.4, which ​is responsible for this message? I think that nothing else has changed.

Version: 2.15.4-stable+timestamp.2017.09.02.04.02.22

(läuft auf nginx/1.10.0, Python 2.7.12)​

No Looks like pypyodbc is not installed properly
