Installed module fileutils 

 sudo pip install abspath

The problem remains

tomjirsa commented 7 years ago

Something has to be changed in web2py framework.

@tomaspvk - please check deploy on your machine to confirm the bug

tomaspvk commented 7 years ago

Seems like the issue is that chgpasswd.py script cannot find gluon directory and import the necessary files from it (such as gluon.fileutils, where the abspath function is located) installing fileutils with pip is unnecessary. Adding 

import sys
sys.path.append("/var/www/web2py/gluon")

to the file makes script successfully execute, however I need to test it a bit more.

tomjirsa commented 7 years ago

Checked the fix.

Error still stays the same, eventhough the chgpasswd.py contains the string:

import sys
sys.path.append("/var/www/web2py/gluon")

Commited new fix, error was in routes.py file, caused by changes in newer version of web2py
