While working with JavaScript, you may encounter the error Webpack: command not found. If you do not know what to do in this case, do not panic yet. Just check out this guide. It will help you solve the problem. Let’s get started!

Webpack is an open-source and free module bundler in the JavaScript programming language. Its primary function is to package JavaScript files for use in browsers, but it may also modify, package, or otherwise organize any asset or resource.

How To Fix Webpack: command not found Error

You can utilize npx to fix the problem Webpack: command not found. 

Using the command npx is the quickest way to fix the problem. Binaries located in the folder node_modules of your project are executed by the command npx.

npx install --save-dev webpack

# or specific version

npm install --save-dev webpack@<version>

You might also locally install webpack. As a result, upgrading projects separately when breaking any changes are made is easier. Typically, more than one npm scripts are used to start webpack, and these scripts will search for an installation in the local directory node_modules.

“scripts”: {

  “build”: “webpack --config webpack.config.js”

Notice that to run webpack local installation, you may access the binary version node_modules/bin/webpack. Also, suppose you are utilizing npm v5.2.0 or higher, you may use npx webpack to perform the task.

Another note is that webpack is not just in your directory node-modules/webpack/bin, it is also attached in node-modules/.bin.

You will have the command npm bin to obtain the folder where executables will be installed by npm.

In this case, you may use the property scripts of the package.json to utilize webpack.

"scripts": {

"scriptName": "webpack --config etc..."

}

The command would now be executed as npm run build rather than directly using webpack in your console.

Here is an example.

"scripts": {

"scriptName": "webpack --config webpack.config.js"

}

Then, you can run the command with:

npm run build

Or with the arguments:

npm run build – <args>

This method enables you to get webpack.config.js within the project’s root folder without needing to install webpack globally or save your webpack settings in the folder node_modules.
