最佳答案

用于迁移的语法不正确。queryInterface.addcolumn方法需要3个参数,而您只传递2个参数。见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');
  }
};

对于任何得到s.replace错误的人来说,这基本上是因为您没有传递预期类型的参数。所以在上面的例子中,一个对象作为第二个参数传递给queryInterface.addColumn,而它需要一个String文本。阅读更多here
