django.db.utils.OperationalError：严重：用户“ deadlylaid”的对等身份验证失败

Question

我在macOS中开发我的项目

我想在ubuntu（AWS）中生产我的项目

（对我的英语水平较低感到抱歉）

$ git clone“ myproject”（在ubuntu / AWS中），我做了很多设置（= MacOs）

我搜索了很多信息..以及这么多解决方案，但它们无法解决我的问题

请有人帮我...

您需要在DATABASES设置中明确指定数据库HOST和PORT 。 当PostgreSQL用户（此处为amulldanji ）与系统用户（此处为ubuntu ）不同时，则需要显式定义数据库主机和端口以使连接正常工作。
