error Module not found: Error: Can't resolve 'babel_loader'


I keep getting the error Module not found: Error: Cannot resolve 'babel_loader' Why? babel-loader is installed in node/modules, @babel-core too, both are also present in package.json. I've tried to reinstall babel-loader, changed webpack.config several times, and restarted both IDE and terminal, and it still doesn't work.

My webpack.config.js

const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");

module.exports = {
  entry: "./src/index.js",
  output: {
    filename: "main.js",
    path: path.resolve(__dirname, "build"),
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: path.join(__dirname, "public", "index.html"),
    }),
  ],
  devServer: {
    static: {
        directory: path.join(__dirname, 'build'),
    },
    port: 3000,
  },
  module: {
    rules: [
        {
            test: /\.(js)$/,
            exclude: /(node_modules)/,
            use: {
                loader: 'babel_loader'
            },
        },
    ]
  },
  resolve: {
    modules: ['node-modules'],
    extensions: ['*', '.js'],
  }
};

My package.json:

{
  "name": "mybuh",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "build": "webpack --mode production",
    "start": "webpack serve --mode development",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-loader": "^9.1.2",
    "@babel/core": "^7.21.8",

  }
}

Solution

  • My problem was, i made a typo, i wrote

    {
        "loader": "babel_loader"
    }
    

    instead of:

    {
        "loader": "babel-loader"
    }
