Question

我在 makemigrations 时遇到此错误

setting.py中数据库的databe设置为：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'freecodeschool',
        'USER': 'fcs_admin',
        'PASSWORD': '',
        'HOST': 'localhost',
        'PORT': '',
    }
}

当我运行迁移时出现此错误。

   return func(*args, **kwargs)
  File "/home/danish-khan/django_drf/django/lib/python3.8/site-packages/django/db/backends/postgresql/base.py", line 187, in get_new_connection
    connection = Database.connect(**conn_params)
  File "/home/danish-khan/django_drf/django/lib/python3.8/site-packages/psycopg2/__init__.py", line 127, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
django.db.utils.OperationalError: fe_sendauth: no password supplied

当我提供密码时，它会给我这个错误。

   connection = Database.connect(**conn_params)
  File "/home/danish-khan/django_drf/django/lib/python3.8/site-packages/psycopg2/__init__.py", line 127, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
django.db.utils.OperationalError: FATAL:  password authentication failed for user "fcs_admin"
FATAL:  password authentication

Answer 1

您似乎还没有填写密码，而您的数据库想要为用户“fcs_admin”提供密码。除此之外，您也应该添加您的数据库端口。（默认为 5432）如果您不确定 postgres 用户的密码，您可以使用以下命令：

sudo su postgres
\du

当我运行 python manage.py makemigrations 时出现此错误
