Mikro-orm 错误：用户“postgres”的密码验证失败

Question

我正在尝试按照这个React GraphQL TypeScript 教程编写代码

该项目使用 MikroOrm 与 PostgreSQL 数据库进行通信。我在我的 Ubuntu 18.04 上安装了 PostgreSQL(12.4)，创建了一个“postgres”用户，我可以登录该用户并正常运行psql。但是，当我开始使用（视频时间戳）之mikro-orm类的命令时，出现以下错误：npx mikro-orm migration:create

error: password authentication failed for user "postgres"

}

这是 PostgreSQL 日志文件中的错误：

2020-08-28 01:45:18.218 EEST [23088] postgres@newstack FATAL:  password authentication failed for user "postgres"
2020-08-28 01:45:18.218 EEST [23088] postgres@newstack DETAIL:  Password does not match for user "postgres".
    Connection matched pg_hba.conf line 96: "host    all             all             127.0.0.1/32            md5"

这是我的 pg_hba.conf：

local   all             postgres                                peer

# TYPE  DATABASE        USER            ADDRESS                 METHOD

local   all             all                                     peer
host    all             all             127.0.0.1/32            md5
host    all             all             ::1/128                 md5
local   replication     all                                     peer
host    replication     all             127.0.0.1/32            md5
host    replication     all             ::1/128                 md5

我想如果连接是本地的，那么它就不需要密码，但为什么不使用本地套接字？如果无法更改，那么我如何向 MikroOrm 提供我的数据库凭据？

像这样将“md5”更改为“信任”：

local   all             all                                     peer
host    all             all             127.0.0.1/32            trust
host    all             all             ::1/128                 trust
local   replication     all                                     peer
host    replication     all             127.0.0.1/32            md5
host    replication     all             ::1/128                 md5
