Я запускаю свой сервер nodejs, и он отображает пустую страницу, но я вижу в инспекторе chrome, что он выводит мой index.html из моей сборки реагирования, но внутри тега <div id='root'></div> ничего нет.
В консоли инспектора у меня есть эта проблема
Uncaught SyntaxError: Unexpected token < main.a3362a52.chunk.js:1
Uncaught SyntaxError: Unexpected token < index.bundle.js:1
Итак, я думаю, что не могу отрисовать свои компоненты из-за этой ошибки /
В результате поиска я нашел две возможности для изучения.
Сначала я попытался решить эту проблему с синтаксической ошибкой, я обнаружил, что это может быть проблемой с babel, поэтому я пытаюсь написать в своем index.html
Он удаляет синтаксическую ошибку о index.bundle.js, но другой в чанке все еще здесь, поскольку он генерируется моей реактивной сборкой.
Затем я попытался выяснить, есть ли проблема с маршрутизатором, поэтому в моем index.js я набрал
ReactDOM.render (test, document.getElementById ('root'));
но этот div не рендерится, так что я думаю, это не проблема роутера.
Мой index.html

и мой webpack.config.js
const webpack = require('webpack');
const path = require('path');
const config = {
entry: './src/index.js',
output: {

console.log(path.resolve(__dirname, 'build'));

Так что я думаю, что проблема возникла из-за Вавилона, но я не знаю, как ее решить, есть ли у вас какие-либо идеи или другие способы, которые я должен использовать для решения своей проблемы?
спасибо
