Node.js is a popular JavaScript runtime environment that allows developers to run server-side applications. If you want to install Node.js on Linux, there are a few different options available. One common method is to use a package manager, such as apt or yum, depending on your Linux distribution.
For Debian-based systems, like Ubuntu, you can use the package manager apt to install Node.js. Open a terminal and run the following commands:
"`
sudo apt update
sudo apt install nodejs
sudo apt install npm
"`
This will install both Node.js and the Node Package Manager (npm) on your system. npm is a powerful package manager for JavaScript libraries and frameworks.
On Red Hat-based systems, such as CentOS or Fedora, you can use the package manager yum. Open a terminal and run the following commands:
"`
sudo yum install nodejs
sudo yum install npm
"`
After the installation is complete, you can verify the installation by running the following commands:
"`
node –version
npm –version
"`
These commands will display the version numbers of Node.js and npm, respectively, if the installation was successful.
Another option is to use a Node.js version manager, such as nvm. This allows you to install and switch between different versions of Node.js on the same machine. To install nvm, you can follow the instructions provided in the official GitHub repository for nvm.
In summary, whether you choose to install Node.js using a package manager or a version manager, both methods will allow you to set up Node.js on your Linux system.
