Prerequisites for Installing Robotjs Globally on Your Machine

Before installing Robotjs globally on your machine, there are a few prerequisites that you need to fulfill. These include:

Node.js and NPM: Robotjs is a Node.js module, so you need to have Node.js (which includes NPM) installed on your machine. You can download and install the latest version from the official Node.js website based on your operating system.
C/C++ Build Tools: Robotjs is a native module that requires C/C++ build tools to compile its code. On Windows, you can install the build tools using the Microsoft Visual C++ Build Tools package. On Mac OS and Linux, you can install them using the command line-based package manager.
Python: Robotjs also requires Python to build certain dependencies. It is recommended to install Python 2.7.x since some libraries that Robotjs depends on may not support the latest version of Python.

Once you have fulfilled these prerequisites, you can proceed to install Robotjs globally on your machine using the npm command: “npm install -g robotjs”.

Step-by-Step Guide to Install Robotjs Globally on Windows Operating System

If you want to use Robotjs, it is important to install it globally on your Windows Operating System. Installing Robotjs can be quite tricky, especially if you are new to it. However, with this step-by-step guide, we will make the process easy for you.

Prerequisites

Before you begin the installation process, make sure that you have the following installed on your system:
