I am following the installation steps mentioned below but have encountered a python problem.

https://en.wikibooks.org/wiki/GNU_Health/Installation#Installing_GNU_Health_on_GNU/Linux_and_FreeBSD

At the step where the initialisation of the database instance is to be performed, I have encountered the following error after executing the following command.

python3 ./trytond-admin --all --database=health

Error encountered: 

Traceback (most recent call last):
  File "./trytond-admin", line 21, in <module>
    admin.run(options)
  File "/home/gnuhealth/gnuhealth/tryton/server/trytond-4.6.18/trytond/admin.py", line 24, in run
    with Transaction().start(db_name, 0, _nocache=True):
  File "/home/gnuhealth/gnuhealth/tryton/server/trytond-4.6.18/trytond/transaction.py", line 88, in start
    database = Database(database_name).connect()

  File "/home/gnuhealth/.local/lib/python3.6/site-packages/psycopg2/pool.py", line 161, in __init__
    self, minconn, maxconn, *args, **kwargs)
  File "/home/gnuhealth/.local/lib/python3.6/site-packages/psycopg2/pool.py", line 58, in __init__
    self._connect()
  File "/home/gnuhealth/.local/lib/python3.6/site-packages/psycopg2/pool.py", line 62, in _connect
    conn = psycopg2.connect(*self._args, **self._kwargs)
  File "/home/gnuhealth/.local/lib/python3.6/site-packages/psycopg2/__init__.py", line 126, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
psycopg2.OperationalError: fe_sendauth: no password supplied


Can anyone help me out with this error or tell me what I am missing?
Based on the error, I suspect that there's a difficulty in connecting to the DB as there is no password specified.

It seems that you did not configured the URI with the credentials to connect to the database. You can find the description of the configuration file at http://docs.tryton.org/projects/server/en/latest/topics/configuration.html#uri Once you have a configuration file, you must run the command like this:

python3 ./trytond-admin --all --database=health -c /path/to/trytond.conf
