Question

ENV：

Postgres：10.2
节点：6.11.0
CLI：2.4.0
ORM：2.1.3

型号：

'use strict';
module.exports = function(sequelize, DataTypes) {
    var test = sequelize.define('test', {
        id: DataTypes.UUID,
        type: DataTypes.STRING,
        data: DataTypes.JSON,
    }, {
        'createdAt': {
            type: Sequelize.DATE(3),
            defaultValue: Sequelize.literal('CURRENT_TIMESTAMP(3)'),
        },
        'updatedAt': {
            type: Sequelize.DATE(3),
            defaultValue: Sequelize.literal('CURRENT_TIMESTAMP(3) ON UPDATE CURRENT_TIMESTAMP(3)'),
        },
        classMethods: {
            associate: function(models) {
                // associations can be defined here
            }
        }
    });
    return test;
}

迁移：

'use strict';
module.exports = {
    up: function(queryInterface, Sequelize) {
        return queryInterface.addColumn('test', {
            test_col: {
                type: Sequelize.JSONB
            }
        });
    },
    down: function(queryInterface, Sequelize) {
        return queryInterface.removeColumn('test', 'test_col');
    }
};

错误：

用于迁移的语法不正确。 queryInterface.addcolumn方法在您仅传递2时需要3个参数。请参阅here。

public addColumn(table: String, key: String, attribute: Object, options: Object): Promise

'use strict';
module.exports = {
  up: function(queryInterface, Sequelize) {
    return queryInterface.addColumn(
          'pages',
          'group',
          Sequelize.JSONB
      );
  },
  down: function(queryInterface, Sequelize) {
    return queryInterface.removeColumn('pages', 'group');
  }
};

对任何得到s.replace错误的人来说，基本上是因为你没有传递预期的论证类型。因此，在上面的情况下，一个对象作为第二个参数传递给queryInterface.addColumn，而期望String字面值。阅读更多here。

TypeError：s.replace不是函数
