我正在尝试使用 sequelize 将 postgresql 与我的节点应用程序一起使用。但我不能让它工作。当我运行时，sequelize -m我得到这个输出：

Loaded configuration file "config/config.json".
Using environment "development".

20130916100313-create-table-usuarios.js

这是我的 config.json：

{
  "development": {
    "username": "cloudlogger",
    "password": "foobar",
    "database": "cloudlogger_dev",
    "dialect":"postgres",
    "protocol":"postgres",
    "host": "127.0.0.1"
  },
  "test": {
    "username": "cloudlogger",
    "password": "foobar",
    "database": "cloudlogger_test",
    "dialect":"postgres",
    "protocol":"postgres",    
    "host": "127.0.0.1"
  },
  "production": {
    "username": "cloudlogger",
    "password": "foobar",
    "database": "cloudlogger_pro",
    "dialect":"postgres",
    "protocol":"postgres",
    "host": "127.0.0.1"
  }
}

这是 20130916100313-create-table-usuarios.js

module.exports = {
  up: function(migration, DataTypes, done) {
    migration.createTable('Usuario',{
      nombre: {
        type: DataTypes.STRING,
        allowBlank: false,
      },
      username: {
        type: DataTypes.STRING,
        unique: true,
      },
      genero: {
        type:   DataTypes.ENUM,
        values: ['Hombre', 'Mujer']
      },
      email: {
        type: DataTypes.STRING,
        unique: true,
        allowBlank: false,
      },
      password_digest: {
        type: DataTypes.STRING,
        allowBlank: false,
      },
      remember_token: DataTypes.STRING,
      superadministrador: {
        type: DataTypes.BOOLEAN,
        defaultValue: false
      },
      token: DataTypes.STRING,
      fecha_token: {
        type: DataTypes.DATE,
        defaultValue: new Date(0)
      },
      lastLogin: DataTypes.DATE
    }).complete(done);
  },
  down: function(migration, DataTypes, done) {
    migration.dropAllTables().complete(done);
  }
}

编辑

如果我评论或更改此行，我隔离了错误：

      genero: {
        type:   DataTypes.ENUM,
        values: ['Hombre', 'Mujer']
      },

它运作良好。好像是 ENUM 类型的问题

您的 ENUM 语法不正确。应该是这样的：

type: DataTypes.ENUM('Hombre', 'Mujer')

如果您有更多问题，请查看有关数据类型的 sequelize 文档

我也有同样的问题。纵观 Postgres 源，似乎 Enum 必须在分配给列类型之前单独创建。

我不确定 sequelize 是否支持此操作
