Question

几天前，我从Windows迁移到linux，并且一直做得很棒，直到我不得不与同事一起进行特定项目为止，现在由于以下原因，我似乎无法启动该应用程序：数据库配置不断被拒绝并引发错误。

我的.env文件

## Setup NODE_ENV
NODE_ENV=development

## Setup your psql development database
DB_USER=postgres
DB_PASS= password
DB_NAME=data
DB_HOST=localhost

现在，此.env配置在Windows计算机上可以正常工作，但是当我尝试在Linux上使用它时，出现以下错误

ERROR: password authentication failed for user "optimusPrime"

有人可以解释为什么它以optimusPrime（这是我的工作名称）optimusPrime@root的身份而不是postgres的身份吗？我该如何配置它或编辑代码以使其与我的Node.js应用程序一起使用linux（我和我的团队正在使用续集ORM），就像在Windows上一样。配置文件看起来像

require('dotenv').config();

module.exports = {
  development: {
    username: process.env.DB_USER,
    password: process.env.DB_PASS,
    database: process.env.DB_NAME,
    host: process.env.DB_HOST,
    dialect: 'postgres',
  }
 }

这是日志文件中的错误

显然，我的pg_hba.conf文件需要进行更好的编辑

sudo nano /etc/postgresql/10/main/pg_hba.conf

所以我以超级用户身份对其进行了打开和编辑，以便使我想使用的用户（我在启动该项目时最初创建的用户）将其从md5更改为trust

# Database administrative login by Unix domain socket
local   all             postgres                                trust

local   all             otherUser                               trust

为了安全起见，如果我将otherUser设置为postgres超级用户，那么我可以更改其密码，也可以在项目中使用它

无法连接到postgres

我的.env文件
