Some more information: if all goes well, you will have a few versions of node installed on your system, nvm makes sure that you can have multiple, and that your command line can easily switch between them. Remember that if you close the command line, and open it up again, your command line will be using the default Node version again. So each time you start developing, it's wise to run nvm use, so you are sure you are using the correct version of Node before you run a Gulp-command.

Make sure you are using the right version of Node as defined in the .nvmrc file before you start. You can install the node-packages with npm or with Yarn.

Both commands have the same result, and you will have a node_modules folder next to where the package.json is located.

That’s it! You can now run Gulp commands!
