意外的令牌错误：标记处index.html中的语法错误； Webpack 4

Question

运行npm build之后，它将在dist文件夹中创建index.html文件，但是它在</script>标记处显示语法错误。一切在本地都可以正常工作（即使出现此语法错误），但在生产中会显示此错误，并且无法部署到Heroku。

下面是代码：dist/index.html

我的package.json文件：

我的webpack.config.js文件：

const HtmlWebPackPlugin = require("html-webpack-plugin");
const htmlPlugin = new HtmlWebPackPlugin({
    template: "./src/index.html",
    filename: "./index.html"
});

module.exports = {
    module:{

                }
            },
            {
                test: /\.html$/,
                use: {
