django postgres 无法连接到服务器：连接被拒绝是主机 "localhost" 上的服务器 运行 (127.0.0.1)
django postgres could not connect to server: Connection refused Is the server running on host "localhost" (127.0.0.1)
我刚刚使用 Zappa 在 aws-lambda 上部署了 Django 应用程序，但出现错误。我不知道是否必须安装 Postgres，因为我认为它是从 requirements.txt
自动安装的

PostgreSQL 不是 python 库，而是一个独立的开源数据库，你绝对应该安装它
在 AWS 领域中，您应该将其设置为 RDS 实例并相应地配置您的环境
