секция ошибки в ds. js

const modelDir = '../../src/models/';
let models = require('fs').readdirSync(require('path').join(__dirname, modelDir));

models.forEach((model,i) => {
    models[i] = require(modelDir.concat(models[i]));
});

импорт также не работает, я получил ошибку, если я использую import

const modelDir = '../../src/models/';
import fs from 'fs';
import path from 'path';
let models = fs.readdirSync(path.join(__dirname, modelDir));

models.forEach((model,i) => {
    models[i] = require(modelDir.concat(models[i]));
});

, если я использую импорт, получил это ошибка
