Postgres 方言在 sequelize 中不起作用

Question

运行我的 Express 项目在装有 pgAdmin4 的 Windows 10 机器上。

在 sequelize/config.json 带有 postgres 方言 的文件中，Sequelize 给出了一些错误。

"development": {
    "username": "root",
    "password": null,
    "database": "database_development",
    "host": "127.0.0.1",
    "port": "5432",
    "dialect": "postgres"
  }

但是使用 sqlite 方言，它工作正常。

"development": {
    "dialect": "sqlite",
    "storage": "./db.development.sqlite"
    }

运行 gulp watch 使用 postgres 方言，出现以下错误：

$ gulp watch

我认为还有一些其他配置需要添加或更改。但我不确定是哪一个。您认为我正在使用的 widows/pgadmin 版本是否导致了其中一些错误或 windows 10 firewall/security 阻塞了端口？

Answer 1

确保：

1) Postgres db is running
2) pg is installed:

npm install --save pg

3) Add also protocol to your config

'dialect':'postgres',
'protocol':'postgres'

Postgres 方言在 sequelize 中不起作用

Postgres dialect is not working in sequelize

postgresql

sequelize.js

windows-10

config.json

pgadmin-4
