ERROR : ImportError: No module named gluon.utils in websocket_messaging.py after upgrade to 2.15.4

[Omicron VT]

I have been using websocket_messaging.py without problems in version 2.14.6. After upgrading to 2.15.4 i can not start websocket_messaging anymore, iget this error :
ImportError: No module named gluon.utils

Any help ? Thanks

had you try:

from gluon import utils

Yes, but no solution.

I think this lines(96-97) in messaging_websocket.py are the problem :
import gluon.utils
from gluon._compat import to_native, to_bytes, urlencode, urlopen

and if i try to import /gluon/utils.py from python console i get a similar error:
  File "utils.py", line 30, in <module>
    from gluon._compat import basestring, pickle, PY2, xrange, to_bytes, to_native
ImportError: No module named gluon._compat

Thanks, but no solution.



To reproduce my problem :
Fresh Debian 9
Download web2py sources for normal users
Unzip web2py to some folder
Install tornado with pip
Cd to web2py folder
Run gluon/contrib/websocket_messaging.py -k mykey -p 8888

This is console output:
root@debian9:~/web2py# python gluon/contrib/websocket_messaging.py -k
mykey -p 8888
Traceback (most recent call last):
File "gluon/contrib/websocket_messaging.py", line 96, in <module>
import gluon.utils

ImportError: No module named gluon.utils

On my Ubuntu working desktop the problem is the same.
If i use an older version of web2py, websocket_messaging works.

Answer to myself:

Maybe solution to problem1 of this issue is the key : https://github.com/web2py/web2py/issues/1696
