After running this command, the package manager will download and install Node.js on your Ubuntu system.

That’s it! You have successfully installed Node.js using the package manager. Now you can start using Node.js to develop and run your applications.

Verify Node.js Installation

After successfully installing Node.js on Ubuntu, it is crucial to verify that the installation was completed correctly. This step ensures that you can start using Node.js and take advantage of its powerful features. To check the installation and ensure it is working, follow the steps below:

Open the terminal on your Ubuntu system.
Type the command node -v and press Enter.
If Node.js is installed correctly, the terminal will display the version number. For example, you might see something like v14.17.0.
Additionally, you can also check the version of npm, the Node.js package manager, by typing npm -v and pressing Enter. This will display the npm version number.

If both Node.js and npm display their respective version numbers without any errors, congratulations! You have successfully verified the installation of Node.js on your Ubuntu system. Now you can start exploring the vast world of Node.js and unleash its potential for your projects.

Install Node.js using Node Version Manager (NVM)

Alternatively, you can use the Node Version Manager (NVM) to install Node.js on Ubuntu. NVM is a handy tool that allows you to manage multiple versions of Node.js on your system. Here’s how you can install Node.js using NVM:

First, you need to install NVM. Open your terminal and run the following command:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

Once NVM is installed, close and reopen your terminal to activate it.
To install the latest version of Node.js, use the following command:

nvm install node

After the installation is complete, you can verify the installed version of Node.js by running:

node -v

That’s it! You have successfully installed Node.js using NVM. With NVM, you can easily switch between different versions of Node.js and keep your development environment flexible.

Install Additional Packages and Modules

When it comes to Node.js, its true potential lies in the vast array of additional packages and modules that can be installed to enhance its functionality and capabilities. In this subheading, we will delve into the process of installing these packages and modules on Ubuntu, allowing you to unlock the full potential of Node.js.

Installing additional packages and modules for Node.js is a straightforward process. One of the most popular tools for managing Node.js packages is npm, the Node Package Manager. With npm, you can easily search for and install packages that suit your specific needs.

To install a package using npm, simply open your terminal and run the following command:

npm install package-name

Replace “package-name” with the name of the package you wish to install. npm will automatically download and install the package, along with any dependencies it may have. It couldn’t be easier!

Furthermore, if you need to install a package globally, meaning it will be accessible across different projects, you can use the “-g” flag. For example:

npm install -g package-name

This will install the package globally, allowing you to use it in any Node.js project on your Ubuntu system.

Additionally, it’s worth mentioning that npm provides a wealth of information and documentation for each package. By visiting the official npm website or the package’s GitHub repository, you can explore the package’s features, usage examples, and any potential issues or updates.

With the ability to easily install additional packages and modules, Node.js becomes an incredibly versatile platform, capable of meeting a wide range of development needs. So go ahead, explore the vast npm ecosystem and unlock the full potential of Node.js on your Ubuntu system!
