Webpack无法解析'babel-loader'

Question

每个人。尝试执行npm run build时出现此错误。这是screen整个过程为webpack配置增加了麻烦。这是关键文件的内容。package.json

{
  "name": "learning-webpack",
  "version": "1.0.0",
  "description": "A package for learning Webpack",
  "main": "index.js",
  "scripts": {
    "build": "webpack --mode development",
    "watch": "webpack --w --mode development"
  },
  "author": "Mikhail Gilodo",

  "devDependencies": {
    "babel": "^6.23.0",
    "babel-core": "^6.26.3",

    "loader": "^2.1.1",
    "webpack": "^4.41.2",
    "webpack-cli": "^3.3.10"
  }
}

webpack.config.js

const path = require("path");                                       

module.exports = {
    entry: './src/index.js',                                        
    output: {
        filename: 'bundle.js',
        path: path.join(__dirname, '/dist')                        
    },
    module: {
        rules: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: {
                    loader: "babel-loader",
                    options: {
                        presets: ['es2015']
                    }
                }
            }
        ]
    }
}

。babelrc

{
    "presets": [
        "es2015"
    ]
}

看来您仍然需要安装“ babel-loader”依赖项。在控制台中：

> npm install -D babel-loader
