Node.js 使用sequelize postgres时出现语法错误

我有一个应用程序正在使用以下配置：

sequelize: 1.7.0
pg: 2.11.1
posgreSql: 9.3 (pg server on my pc)

它与

sequelize

和

mysql

方言一起工作。 当我将其更改为：

db: 'mysql://user:pass@localhost/dbname'

然后转到

postgres

并尝试

sequelize.sync（）

我收到以下错误：

db: 'postgres://user:pass@localhost/dbname'

我做错了什么

在我在pg中创建

dbname

数据库之前，有一个错误

缺少数据库

，所以我猜sequelize连接到pg，但它在pgsql代码中生成了一些语法错误

问题是，在模型模式中，我有Sequelize.INTEGER（11）-postgres不允许将11作为整数的大小传递-这将在Sequelize的2.x.x版本中解决（您可以在Sequelize github repo上找到与此问题对应的问题）.

Sequelize和postgres对我来说很好。您是否在config.js中正确设置了方言、协议和端口

抱歉，我忘了写下这一问题已经解决了-问题是在模型模式中我有

Sequelize.INTEGER（11）

-并且postgres不允许将

11

作为整数大小传递-这将在Sequelize的

2.x.x

版本中解决（您可以在Sequelize github repo上找到与此问题对应的问题）。

    "username":"name",

    "port":"5432"
