我不确定我是否做错了什么。我觉得我在运行一个现代的、相当普通的堆栈。但是我无法让新的sequelize v6与我的设置很好地配合。我在节点v14.17，sequelize v6.6.2上，在我的package.json中有 "type": "module" . 我终于想出了如何通过大量的谷歌搜索和修补来自动导入我的模型。因此，现在我尝试使用迁移工具向模型添加一个字段。我在migrations文件夹中创建了迁移文件。
看起来是这样的：

'use strict';

module.exports = {
    up: async (queryInterface, Sequelize) => {
        /**
         * Add altering commands here.
         *
         * Example:
         * await queryInterface.createTable('users', { id: Sequelize.INTEGER });
         */
        return Promise.all([
            queryInterface.addColumn(
                'Customers', // table name
                'include_core_items', // new field name
                {
                    type: Sequelize.Boolean,
                    allowNull: false,
                    defaultValue: true,
                    after: 'customer_name',
                }
            ),
        ]);
    },

    down: async (queryInterface, Sequelize) => {
        /**
         * Add reverting commands here.
         *
         * Example:
         * await queryInterface.dropTable('users');
         */
        return Promise.all([
            queryInterface.removeColumn('Customers', 'include_core_items'),
        ]);
    },
};

然后我尝试使用以下工具运行迁移： npx sequelize-cli db:migrate 我得到以下错误： ERROR: Error reading "config\config.js". Error: Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: C:\...\config\config.js require() of ES modules is not supported. require() of C:\...\config\config.js from C:\Users\...\AppData\Roaming\npm-cache\_npx\12576\node_modules\sequelize-cli\lib\helpers\config-helper.js is an ES module file as it is a .js file whose nearest pare nt package.json contains "type": "module" which defines all .js files in that package scope as ES modules. Instead rename config.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from C:\...\package.json. 我已尝试将配置重命名为.cjs，然后出现错误： ERROR: Dialect needs to be explicitly supplied as of v4.0.0 因此，我认为它不能正确地读取env变量或其他内容。
配置[c]js
