我正在做一個來自https://medium.com/ethereum-developers/the-ultimate-end-to-end-tutorial-to-create-and-deploy-a-fully-descentralized-dapp-in的相當簡單的項目-ethereum-18f0cf6d7e0e由于本教程不關注前端部分（webpack 和 babel 等），我從不同的地方挑選了這些步驟?，F在我嘗試使用 webpack 和 http-server 構建前端，但我意識到它并沒有隨著我對文件所做的更改而更新。webpack.config.jsconst path = require('path')module.exports = {   entry: path.join(__dirname, 'src/js', 'index.js'), // Our frontend will be inside the src folder   output: {      path: path.join(__dirname, 'dist'),      filename: 'build.js' // The final file will be created in dist/build.js   },   module: {      rules: [{         test: /\.css$/, // To load the css in react         use: ['style-loader', 'css-loader'],         include: /src/      }, {         test: /\.jsx?$/, // To load the js and jsx files         loader: 'babel-loader',         exclude: /node_modules/,         query: {            presets: ['@babel/preset-env', '@babel/preset-react']         }      }]   }}包.json{  "name": "test-app",  "version": "1.0.0",  "main": "index.js",  "scripts": {    "test": "echo \"Error: no test specified\" && exit 1"  },  "keywords": [],  "author": "",  "license": "ISC",  "devDependencies": {    "@babel/core": "^7.10.2",    "@babel/preset-env": "^7.10.2",    "@babel/preset-react": "^7.10.1",    "babel-loader": "^8.1.0",    "css-loader": "^3.5.3",    "json-loader": "^0.5.7",    "react": "^16.13.1",    "react-dom": "^16.13.1",    "style-loader": "^1.2.1",    "web3": "^0.20.0",    "webpack": "^4.43.0",    "webpack-cli": "^3.3.11"  },  "directories": {    "test": "test"  },  "dependencies": {},  "description": ""}我使用它構建它 npx webpack --config webpack.config.js  然后上桌 http-server dist/我該如何解決？這甚至是正確的方法嗎？謝謝。
