Question

使用pgAdmin4在Windows 10计算机上运行Express项目。

在带有 postgres dialect 的sequelize/config.json文件中，Sequelize会出现一些错误。

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

但是使用 sqlite dialect ，它可以正常工作。

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

使用postgres方言运行gulp watch，出现以下错误：

$ gulp watch

我认为还需要添加或更改其他配置。但我不确定是哪一个。你认为我正在使用的widows / pgadmin版本是否会导致其中一些错误或者Windows 10防火墙/安全阻塞端口？

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方言不适用于sequelize
