我正在将typeorm添加到我的Next.js应用程序中。然而，即使我使用mysql2驱动程序和5个数据源，我似乎也无法摆脱bson错误：

./node_modules/typeorm/browser/driver/mongodb/bson.typings.js
Module parse failed: Export 'BSON' is not defined (1:9)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
> export { BSON };
| 
| //# sourceMappingURL=bson.typings.js.map

下面是我尝试使用的主要数据源：

export const MI_Website = new DataSource({
    type: "mysql",
    host: process.env.BD_HOST as string,
    // port: process.env.DB_PORT || 3306,
    port: parseInt(process.env.DB_PORT as string) || 3306,
    username: process.env.DB_USERNAME as string,
    password: process.env.DB_PASSWORD as string,
    database: process.env.DB_DATABASE1 as string,
    entities: [__dirname + "/entity/website/*{.jsx,.tsx,.js,.ts}"],
    synchronize: true,
})

帮助将不胜感激。dispensing搜索我还没有找到任何修复这个问题只是尚未。
