Question

因此，我已经使用AWS EC2部署了我的项目。我也试图在本地服务器上运行该应用程序以进行测试。但随后出现以下错误。

Traceback (most recent call last):
  File "C:\Users\user\Envs\venv\lib\site-packages\django\db\backends\base\base.py", line 220, in ensure_connection
    self.connect()
  File "C:\Users\user\Envs\venv\lib\site-packages\django\utils\asyncio.py", line 26, in inner
    return func(*args, **kwargs)
  File "C:\Users\user\Envs\venv\lib\site-packages\django\db\backends\base\base.py", line 197, in connect
    self.connection = self.get_new_connection(conn_params)
  File "C:\Users\user\Envs\venv\lib\site-packages\django\utils\asyncio.py", line 26, in inner
    return func(*args, **kwargs)

    connection = Database.connect(**conn_params)
  File "C:\Users\user\Envs\venv\lib\site-packages\psycopg2\__init__.py", line 127, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
psycopg2.OperationalError

我在settings.py

中有这个

import os
from .local_settings import PG_HOST

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME' : 'myDB',
        'USER' : 'Manager',
        'PASSWORD' : '###password###',
        'HOST' : PG_HOST,
        'PORT' : '',
    }
}

这在local_settings.py中。（未在AWS服务器中使用）

PG_HOST = ''

您认为错在哪里？预先非常感谢。

尝试在本地服务器上运行时如何解决psycopg2错误？
