Install the external dependencies of a Catalyst Serverless function in its functions/{function_name} folder on your local machine. Navigate to that folder path, and then install the Node modules if it is a Node.js function, or the JAR dependencies inside the lib folder if it is a Java function. For a Python function, you can install the required Python packages.
