Question

使用以下命令会出现问题：

knex --knexfile config/db/knexfile.js migrate:latest

我收到以下错误：

Knex:warning - Pool2 - Error: Pool was destroyed
Knex:Error Pool2 - error: password authentication failed for user "dennis"

似乎它没有使用我的UNIX帐户，而是尝试使用用户名/密码进行身份验证。

我尝试了以下解决方案：

将pg更新为最新的
将knex更新为最新的
将信任方法替换为：

# IPv4 local connections: host all all 127.0.0.1/32 trust

将连接字符串从[db name]替换为[postgres://[db name]：

connection: {
  database: 'postgres://data-api-dev',
  user:     '',
  password: ''
},

如何让它使用我的UNIX帐户？

我使用Node v6.3.1在Ubuntu 16.04上。

事实证明，将方法从md5重命名为trust是正确的解决方案。我在进行更改后忘记重新启动postgresql服务，因此第一次无效。
