Metro错误不支持定义的动态请求，当将Sequelize与react-native一起使用时

Question

我在一个react-native ios应用程序中使用node_module Sequelize，位于node_module/sequelize文件夹中的文件data-types.js导致react-native应用程序构建失败，错误为Dynamic require defined at line 1033; not supported by Metro

data-tyes.js中的代码部分，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 
}

​

有谁有解决这个问题的办法吗？

我不得不修改它的代码：

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);
