Django fe_sendauth：未提供密码错误，无法连接到 postgres 数据库

Question

我正在尝试使用 django 应用程序配置服务器，并将 postgresql 作为其后端。当我尝试运行迁移时安装所需的包、数据库和环境后，出现以下错误

Traceback (most recent call last):
  File "/var/envs/traveldbapi/lib/python3.4/site-packages/django/db/backends/base/base.py", line 213, in ensure_connection
    self.connect()
  File "/var/envs/traveldbapi/lib/python3.4/site-packages/django/db/backends/base/base.py", line 189, in connect
    self.connection = self.get_new_connection(conn_params)
  File "/var/envs/traveldbapi/lib/python3.4/site-packages/django/db/backends/postgresql/base.py", line 176, in get_new_connection
    connection = Database.connect(**conn_params)
  File "/var/envs/traveldbapi/lib/python3.4/site-packages/psycopg2/__init__.py", line 130, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
psycopg2.OperationalError: fe_sendauth: no password supplied


The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)
  File "/var/envs/traveldbapi/lib/python3.4/site-packages/django/core/management/__init__.py", line 363, in execute_from_command_line
    utility.execute()

    connection = Database.connect(**conn_params)

    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
django.db.utils.OperationalError: fe_sendauth: no password supplied

我确认DATABASE存在django所需的相关设置：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'HOST': 'localhost',
        'NAME': DATABASE_NAME,
        'USER': DATABASE_USER,
        'password': DATABASE_PASSWORD
    }
}

我不确定为什么会发生此错误，因为这与我在本地计算机上使用的设置相同，并且可以正常工作。为了确认我的没有任何问题，我pg_hba.conf从全新安装开始。配置没有以任何方式修改，应用程序用户对应用程序数据库具有所需的权限。

设置必须大写 - 尝试将其更改为 'PASSWORD'
