Error: Cannot find module 'html-webpack-plugin' - Webpack (React)

Question

I tried to create a basic React app with webpack 4 following this link

until installing "html-webpack-plugin", I did not face any errors. But, once I run the command "npm run start", I keep getting the following error:

**Error: Cannot find module 'html-webpack-plugin'
    at Function.Module._resolveFilename (module.js:547:15)
    at Function.Module._load (module.js:474:25)
    at Module.require (module.js:596:17)**

I tried to solve this issue using the following two threads by installing packages globally and locally, but it didn't help.

Please see my code below:

package.json:

{
  "name": "react_website",
  "version": "1.0.0",
  "description": "Website using React and Webpack",
  "main": "index.js",
  "scripts": {
    "start": "webpack --mode development",
    "build": "webpack --mode production"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-core": "^6.26.3",
    "babel-loader": "^7.1.5",
    "babel-preset-env": "^1.7.0",
    "babel-preset-react": "^6.24.1",
    "html-webpack-plugin": "^3.2.0",
    "webpack": "^4.16.2",
    "webpack-cli": "^2.1.5"
  },
  "dependencies": {
    "react": "^16.4.1",
    "react-dom": "^16.4.1"
  }
}

webpack.config.js:

const HtmlWebPackPlugin = require("html-webpack-plugin");

module.exports = {
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader"
        }
      }
    ]
  },
  plugins: [
    new HtmlWebPackPlugin({
    template: "./src/index.html",
    filename: "./index.html"
  })
],
};

- .babelrc:

{
  "presets": ["env", "react"]
}

Answer 1

Use this command:

npm i --save-dev html-webpack-plugin

Answer 2

Try removing Node Modules: rm -rf node_modules.

Next re-install all dev dependencies npm install.

Lastly, re-install the html-webpack-plugin npm i html-webpack-plugin --save-dev.

I would also suggest making sure all of the directory paths are correct and that you're inside the actual project folder. This is rare, but can happen from time to time.
