Webpack-dev-server“无法获取/”

Question

我正在尝试让我的 webpack-dev-server 运行，但我在浏览器上总是遇到“无法获取/”错误。我知道有几个问题有同样的错误，但没有一个对我有帮助，所以现在我要试试运气:)

这些是我的 webpack-config.js 配置：

const path = require('path');

module.exports = {
  mode: 'development',
  entry: './src/app.ts',
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist')
  },
  devtool: 'inline-source-map',
  module: {
    rules: [
      {
        test: /\.ts$/,
        use: 'ts-loader',
        exclude: /node_modules/
      }
    ]
  },
  resolve: {
    extensions: ['.ts', '.js']
  }
};

包.json：

{
  "name": "ts",
  "version": "1.0.0",
  "description": "test",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "webpack-dev-server",
    "build": "webpack"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "clean-webpack-plugin": "^4.0.0",
    "html-loader": "^3.1.0",
    "html-webpack-plugin": "^5.5.0",
    "lite-server": "^2.6.1",
    "ts-loader": "^9.2.8",
    "typescript": "^4.6.2",
    "webpack": "^5.70.0",
    "webpack-cli": "^4.9.2",
    "webpack-dev-server": "^4.7.4"
  },
  "dependencies": {
    "lodash": "^4.17.21"
  }
}

从index.html 查找bundle.js 的脚本如下所示：

<script type="module" src="dist/bundle.js"></script>

旁注：index.html 不像bundle.js 那样位于 dist 文件夹中，但无论如何我都会遇到相同的错误。

Answer 1

尝试设置output.publicPath为auto

并通过 webpack 运行开发服务器：

您还需要一个 html 文件：
