如何安装GNUHealth？

Question

我遵循下面提到的安装步骤，但遇到了python问题。你知道吗

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

在要执行数据库实例初始化的步骤中，我在执行以下命令后遇到了以下错误。你知道吗

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

遇到错误：

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/gnuhealth/tryton/server/trytond-4.6.18/trytond/backend/postgresql/database.py", line 97, in __new__
    **cls._connection_params(name))
  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

有谁能帮我解决这个错误，或者告诉我遗漏了什么？
基于这个错误，我怀疑连接到数据库有困难，因为没有指定密码。你知道吗

似乎您没有使用连接到数据库的凭据配置URI。您可以在http://docs.tryton.org/projects/server/en/latest/topics/configuration.html#uri找到配置文件的描述 一旦有了配置文件，就必须像这样运行命令：

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