webpack-dev-server: command not found

To resolve the issue "webpack-dev-server: command not found", you can try the following steps:

1. Make sure you have webpack-dev-server installed as a dependency in your project. To do this, navigate to your project directory and run the following command:

   npm install webpack-dev-server --save-dev

This command will install webpack-dev-server locally in your project.

2. If you already have webpack-dev-server installed, make sure it is added to the `devDependencies` section of your project's `package.json` file. If it is not listed there, manually add it using the following command:

   npm install webpack-dev-server --save-dev

3. After installing or confirming the installation of webpack-dev-server, try running the command again. If the issue persists, try running the command using the `npx` command:

   npx webpack-dev-server

This will execute the webpack-dev-server command using the locally installed version.

If none of these steps resolve the issue, please provide more details about your project setup and configuration, as well as any error messages you are receiving.
