1. Start by examining your node_modules directory.

Whenever you add npm packages, a node_modules folder is generated in the root of your project. The packages are recorded in your package.json and package-lock.json files. To verify that a package was successfully installed, ensure it is listed in these two files. Additionally, don't forget to check the node_modules folder to confirm the presence of the package within a subfolder.

2. Proceed with installing the module.

If gulp is indicating that a package is missing, include it in your package.json and execute npm install.
