[Health] Creating the GNU Health database

[William Moura]

Hi everyone,

I have installed GNU Health, on Ubumtu 14.04 LTS following all steps and requirements in https://en.wikibooks.org/wiki/GNU_Health/Installation but I didn't succeed yet. I have the Tryton Client installed on the same machine but in another user. My pg_hba.conf is set as follows:

local   all             all                                     trust

host    all             all             127.0.0.1/32            trust

My trytond.conf is set as follows:

[database]

uri = postgresql://localhost:5432

path = /home/gnuhealth/attach

[session]

super_pwd = M0thnfkds987

[jsonrpc]

listen: *:8000

The error I have recieved is:

3405 140594225813248 [2016-04-24 15:52:10,305] ERROR trytond.protocols.dispatcher CREATE DB: gnuhealth failed Traceback (most recent call last): File "/home/gnuhealth/gnuhealth/tryton/server/trytond-3.8.5/trytond/protocols/dispatcher.py", line 229, in create pool.init(update=['res', 'ir'], lang=[lang]) File "/home/gnuhealth/gnuhealth/tryton/server/trytond-3.8.5/trytond/pool.py", line 144, in init self.start() File "/home/gnuhealth/gnuhealth/tryton/server/trytond-3.8.5/trytond/pool.py", line 97, in start register_classes() File "/home/gnuhealth/gnuhealth/tryton/server/trytond-3.8.5/trytond/modules/__init__.py", line 319, in register_classes import trytond.ir File "/home/gnuhealth/gnuhealth/tryton/server/trytond-3.8.5/trytond/ir/__init__.py", line 4, in <module> from .configuration import * File "/home/gnuhealth/gnuhealth/tryton/server/trytond-3.8.5/trytond/ir/configuration.py", line 3, in <module> from ..model import ModelSQL, ModelSingleton, fields File "/home/gnuhealth/gnuhealth/tryton/server/trytond-3.8.5/trytond/model/__init__.py", line 3, in <module> from .model import Model File "/home/gnuhealth/gnuhealth/tryton/server/trytond-3.8.5/trytond/model/model.py", line 9, in <module> from trytond.model import fields File "/home/gnuhealth/gnuhealth/tryton/server/trytond-3.8.5/trytond/model/fields/__init__.py", line 4, in <module> from .field import * File "/home/gnuhealth/gnuhealth/tryton/server/trytond-3.8.5/trytond/model/fields/field.py", line 7, in <module> from sql import operators, Column, Literal, Select, CombiningQuery, Null ImportError: cannot import name Null

Please, any helping would be welcome!
