Before we dive into the intricacies of the ‘run dev mix’ error that many professionals in the field of JavaScript programming encounter, it is essential to understand what ‘mix’ is. Laravel Mix is a fluent API for defining Webpack build steps for your JavaScript applications using several common CSS and JavaScript pre-processors. However, users may stumble upon the “run dev mix not found” error message, which can be quite perplexing, especially for beginners.
Now, let’s take a tour together through the process of solving this issue, and the concept behind the code that we would use to solve it.
The solution to ‘run dev mix not found’
One popular solution to tackle this problem is to ensure that all dependencies are installed correctly. You can get this done by running the command
npm install
. This command installs a package, and any packages that it depends on. However, if the problem continues to persist after running this command, it means that the problem is perhaps not with the dependencies installation.
Another way to solve this is to make sure that the scripts are defined properly in your ‘package.json’ file. Here is how it should look:
"scripts": {
"dev": "npm run development",
"development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch": "npm run development -- --watch",
"hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
"prod": "npm run production",
"production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
}
A Deep Dive into the Code
Let’s break down what’s happening in this code. The “scripts” object is part of the ‘package.json’ file that allows you to alias long commands with short ones. In our scenario, we’re using the “dev” script to execute the “npm run development” command. We’re also making use of “cross-env” to set environment variables across platforms.

- Webpack: This utility is a static module bundler for modern JavaScript applications. It builds a dependency graph that maps every module your project needs and generates one or more bundles.
- Laravel Mix: This is a helpful tool that allows developers to define Webpack build steps for their JavaScript applications in a fluent manner.
Now, you should be able to run the ‘npm run dev’ command without encountering the “run dev mix not found” error message. It’s always satisfactory to see our applications run smoothly without any hiccups, and I hope this comprehensive solution has helped you achieve just that.
