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

使用这个命令：

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.

Answer 3

In my case, using typescript, sublime didn't pick it up. Don't even need to install @types/html-webpack-plugin , it already exists. Just needed to restart the IDE for it to register.

Answer 4

您还可以使用以下命令解决错误。

npm install html-webpack-plugin
