Node.js is a popular JavaScript runtime that allows developers to build fast and scalable applications on the server-side. If you’re an Ubuntu user and want to use Node.js for web development, you’ll need to install it on your machine. In this article, we’ll provide a complete guide on how to perform a Node.js installation on Ubuntu, including system requirements, two different installation methods, and troubleshooting tips. Whether you’re a beginner or an experienced developer, this guide will help you get started with Node.js on Ubuntu.
System Requirements for Node.js Installation on Ubuntu
For Node.js Installation on Ubuntu, System Requirements
Make sure your system complies with the minimum requirements before you proceed with the installation. The requirements for installing Node.js on Ubuntu are as follows:
- or later, Ubuntu 18.04 LTS
- at least 2 GB of RAM
- At least two CPU cores are required.
- at least 10 GB of free disk space
By adhering to these system requirements, you can make sure that Node.js functions efficiently on your Ubuntu system and that the installation process goes smoothly.
Keep in mind that Node.js might support older versions of Ubuntu, but the installation process might be more difficult and might not be official supported byNode.js. As a result, it is advised to use the most recent version of Ubuntu to guarantee the best performance and Node.js compatibility.
Method 1: Install Node.js on Ubuntu using the Default Repositories
The first step is Method 1: Utilize the default Repositories to install Node.js on Ubuntu
Using the default repositories on Ubuntu is the simplest way to install Node.js. Beginners and those who need to install Node.js quickly and easily should use this method.
Follow these instructions to install Node.js in the default repositories:
Ctrl T is the key to launch the terminal on your Ubuntu machine.
By using the following commands, update the package list and upgrade the packages on your machine:
``Bash
,`.
sudo apt update:
sudo apt upgrade
You can make sure you have the most recent versions of the required dependencies by updating the package list and upgrading the packages.
3. The following command will enable Node.js to install:
```Bash`,`.
sudo apt install nodejs
Node.js and the Node package manager will be installed as a result.
- By using the following command, you can confirm that Node.js is installed properly:
``Bash
,`.
node -v
The version of Node.js you've installed should be output by this command.
Benefits and Drawbacks of Using Method 1
The benefits of using Method 1 to install Node.js on Ubuntu are:
- Using the default repositories, Node.js installation is simple and fast.
- On Ubuntu, Node.js installation is supported by this method.
The drawbacks of using Method 1 to install Node.js on Ubuntu are:
- It might not install the most recent version of Node.js.
- It might not offer the flexibility to switch between various Node.js versions.
Using Method 1, Uninstalling Node.js
Use Method 1 to uninstall Node.js that was installed:
```Bash`,`.
Nodejs should not be removed from the apt tree.
Your Ubuntu machine will be free of Node.js and the npm package manager as a result.
If you’re new to Node.js or are new to Ubuntu, using Method 1 to installNode.js on Ubuntu is a great place to start. However, think about using Method 2 (installing Node.js using NVM) as an alternative if you need to install multiple versions ofNode.js or need more flexibility when managing your Node.JS installations.
Method 2: Install Node.js on Ubuntu with NVM
Node Version Manager (NVM) is a command-line tool you can use if you want to install and manage several versions of Node.js on the same system.
The installation of Node.js on Ubuntu using NVM follows the following steps:
Ctrl T is the key to open the terminal after pressing it.
The following command will enable NVM installation:
``Bash
,`.
curl -o- v0.38.0, install.sh, and more are available at https://raw.githubusercontent.com/nvm-sh
This runs the NVM installation script in your terminal after downloading it from the official NVM repository.
3. To begin using NVM, close the terminal and open it again. To load NVM into your shell session, this is necessary.
4. By using the following command, you can install the most recent Node.js version:
```Bash`,`.
Node installation with nvm
This installs Node.js’ most recent stable version.
- By using the following command, you can confirm that Node.js is installed properly:
``Bash
,`.
node -v
The version of Node.js you installed using NVM should be displayed by this command.
Use of Method 2: Some Benefits
The benefits of using Method 2 to install Node.js on Ubuntu are:
- You can quickly switch between various Node.js versions thanks to it.
- By default, it installs Node.js' most recent version.
- It offers greater flexibility when handling Node.js versions.
Using Method 2, uninstalling Node.js
The following command should be used to uninstall Node.js that was installed by Method 2:
```Bash`,`.
node nvm uninstall
This removes the version of Node.js you installed using NVM from your system.
Troubleshooting Node.js Installation on Ubuntu
If you encounter issues during the Node.js installation process on Ubuntu, try the following troubleshooting tips:
- Ensure that your system meets the minimum requirements for installing Node.js on Ubuntu. Refer to section II for the minimum system requirements.
- Ensure that you have followed the correct installation steps for your chosen method. Refer to sections III and IV for step-by-step installation guides.
- Check that you have the latest version of Ubuntu and that your system is up to date. Use the following command to update your system:
bash
sudo apt update && sudo apt upgrade - If you are using Method 2, ensure that you have installed NVM correctly and that it is being used to manage Node.js versions. Refer to section IV for the installation guide.
- If you encounter any error messages during installation, search for the error message online for possible solutions.
To verify that Node.js is properly installed on Ubuntu, run the following command in your terminal:
node -v
This command should output the version of Node.js that you have installed. If the command does not output a version number, try reinstalling Node.js using the correct installation method or consult the Node.js documentation for troubleshooting tips.
Insider Tips
- Use
sudo
before any installation command to run the command with elevated privileges. - Use
npx
to run Node.js scripts without installing them globally. - Use
npm audit
to check your application’s dependencies for known vulnerabilities.
Following these tips can help you avoid common issues during Node.js installation and ensure that your Node.js application runs smoothly on Ubuntu.
Real-Life Personal Story
I once worked on a project that required creating a high-performance web application that could handle a lot of traffic as a web developer. As Node.js is renowned for its scalability and capacity to handle a large number of concurrent connections, we made the decision to build the application’s backend using it.
The default repositories installation method on Ubuntu was the first option we used. But as we advanced, we understood that we needed to switch to NVM to manage various Node.js versions for our project. To test the compatibility of our application with various versions of Node.js using NVM, we were able to quickly switch between various Node.JS versions.
We were able to create a highly scalable and performant web application that could handle the expected volume of traffic using Node.js and NVM. We also appreciated the ease with which NVM managed various Node.js versions, which made it simple for us to modify our application as necessary.
During the installation process, we faced some difficulties, but with the aid of online resources and the Node.js community, we were able to get past them. We were able to troubleshoot problems quickly and accurately because the installation process was well-documented and straightforward.
Overall, using both the default repositories and NVM to install Node.js on Ubuntu was both easy and successful. We strongly advise using Node.js for creating high-performance web applications and NVM for managing various Node.JS versions.
We advise looking into online resources and the Node.js community for support if you’re having any problems during the installation process or need assistance managing various versions ofNode.js.
