javascript - 将 Sequelize 与 react-native 一起使用时，Metro 错误不支持定义的动态需求

Question

我在 react-native ios 应用程序中使用 node_module Sequelize，data-types.js位于 node_module/sequelize 文件夹中的文件导致 react-native 应用程序构建失败并出现错误Dynamic require defined at line 1033; not supported by Metro

data-types.js 中的代码部分，第 1033 行：

const dialectNames = ['postgres', 'mysql', 'mariadb', 'sqlite', 'mssql'];
const dialectMap = {};
for (const d of dialectNames) {
  dialectMap[d] = require(`./dialects/${d}/data-types`)(DataTypes);//<--Line 1033 
}

有人能解决这个问题吗？

不得不改变它的工作代码：

const dialectNames = ['postgres', 'mysql', 'mariadb', 'sqlite', 'mssql'];
const dialectMap = {};
//for (const d of dialectNames) {
//  dialectMap[d] = require(`./dialects/${d}/data-types`)(DataTypes);
//}
dialectMap['postgres'] = require(`./dialects/postgres/data-types`)(DataTypes);
dialectMap['mysql'] = require(`./dialects/mysql/data-types`)(DataTypes);
dialectMap['mariadb'] = require(`./dialects/mariadb/data-types`)(DataTypes);
dialectMap['sqlite'] = require(`./dialects/sqlite/data-types`)(DataTypes);
dialectMap['mssql'] = require(`./dialects/mssql/data-types`)(DataTypes);
