django.db.utils.OperationalError: connection to server at "localhost" (::1), port 5432 failed: fe_sendauth: no password supplied

Answer 1

由于返回的错误是django.db.utils.OperationalError: connection to server at "localhost" (::1), port 5432 failed: fe_sendauth: no password supplied ，我假设缺少设置数据库密码的环境变量。

Answer 2

您的database连接似乎有错误。 在您的settings.py文件中使用并用您自己的凭据替换以下代码片段。 快乐编码

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'YOUR_DATABASE_NAME',
        'USER': 'YOUR_DATABASE_USERNAME',
        'PASSWORD': 'YOUR_DATABASE_USERNAME',
        'HOST': 'localhost',
        'PORT': '5432',

        # Use the below Options when you have a Postgresql server with SSL.
        # 'OPTIONS': {
        #     'sslmode': 'require',
        # }
    }
}
