Handlebars 内置 Helpers 日志不适用于 webpack？

如何解决Handlebars 内置 Helpers 日志不适用于 webpack？

我有一个带把手的 webpack 项目。我想使用内置助手 {{log "test"}} 但没有结果。使用 gulp，相同的代码在控制台中给出输出。我不明白这是怎么回事。其余的助手工作良好。问题仅在 {{log}} 中。 我的 webpack 配置不正确吗？

const
   path = require( 'path' ),webpack = require( "webpack" ),HTMLWebpackPlugin = require( 'html-webpack-plugin' ),{CleanWebpackPlugin} = require( 'clean-webpack-plugin' ),MiniCssExtractPlugin = require( 'mini-css-extract-plugin' ),CssMinimizerPlugin = require( 'css-minimizer-webpack-plugin' ),TerserPlugin = require( 'terser-webpack-plugin' )

const isDev = process.env.NODE_ENV === 'development'
const isProd = !isDev

module.exports = {
   mode: 'development',context: path.resolve( __dirname,'src' ),entry: { 
      main: './main.js'
   },output: { 
      filename: 'bundle.js',path: path.resolve( __dirname,'dist' )
   },devServer: { 
      contentBase: path.join( __dirname,'dist' ),port: 3000,open: false,overlay: true,stats: 'errors-only',},resolve: {
      extensions: ['.css','.scss','.js','.json'],alias: {
         '@': path.resolve( __dirname,'src' ) 
      }
   },plugins: [
      new webpack.ProvidePlugin( {

            const cities = require( './src/json/cities' )
            const unite = require( './src/json/unite' )

            return {tariffs,performance,info,cities,unite}
         },minify: isProd,new MiniCssExtractPlugin( {
         filename: 'style.css',new CleanWebpackPlugin(),],module: {
