Updating Node.js in Ubuntu 18.04 is a simple task, but it's important to do it right to avoid any issues with your development environment. In this article, we'll walk you through the process of updating Node.js on Ubuntu 18.04 with code examples.
Step 1: Update your package list
Before updating Node.js, it's essential to update your package list to make sure you have access to the latest packages. You can do this by running the following command in your terminal:
sudo apt-get update
This command will take a few seconds to update your package list, so be patient.
Step 2: Install NVM
Node Version Manager (NVM) is the most popular tool for managing Node.js versions on Linux systems. You can install NVM by running the following command in your terminal:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash
This command will download and install NVM on your Ubuntu 18.04 system. Once you've installed NVM, you can use it to install or update Node.js.
Step 3: Install Node.js
After installing NVM, you can use it to install the latest version of Node.js by running the following command in your terminal:
nvm install node
This command will download and install the latest version of Node.js on your Ubuntu 18.04 system. Once the installation is complete, you can check the version of Node.js by running the following command in your terminal:
node -v
This command will display the current version of Node.js installed on your system.
Step 4: Switch between Node.js Versions
NVM allows you to switch between different versions of Node.js easily. For example, if you want to use Node.js version 14.15.4, you can use the following command:
nvm install 14.15.4
Once the installation is complete, you can switch to the new version by running the following command:
nvm use 14.15.4
This command will set the Node.js version to 14.15.4, and you can use it for your project.
Step 5: Update Node.js
NVM makes it easy to update Node.js to the latest version. You can update Node.js by using the following command in your terminal:
nvm install node --reinstall-packages-from=node
This command will install the latest version of Node.js and reinstall existing packages from the previous version. Once the installation is complete, you can check the version of Node.js by running the following command in your terminal:
node -v
Conclusion
Updating Node.js on Ubuntu 18.04 is an essential task for developers to ensure that their development environment is up-to-date. By following the steps mentioned in this article, you can easily update Node.js and switch between different versions using NVM.
here are some additional details you might find useful:
Step 2: Install NVM
Node Version Manager (NVM) is a fantastic tool for managing multiple versions of Node.js on your system. It allows you to install and switch between different versions of Node.js with ease, making it ideal for developers who work on projects with different dependencies.
You can install NVM by either using the installation script or by manually downloading and installing it from the NVM GitHub repository. The installation script method is the most recommended approach, as it ensures that you have the latest version of NVM installed and configured correctly.
Once you have NVM installed, you need to restart your terminal or source ~/.bashrc to start using it.
Step 3: Install Node.js
After installing NVM, you can use it to install specific versions of Node.js. For example, if you need to install Node.js version 14.15.1, you can use the following command:
nvm install 14.15.1
NVM downloads the specified version of Node.js from the official Node.js website and installs it on your system. Once the installation is complete, you can verify the installed version of Node.js by running the following command:
node -v
The above command displays the version number of the currently active Node.js version.
Step 4: Switch between Node.js versions
NVM makes it easy to switch between different versions of Node.js. To switch to version 14.15.1 you can use this command:
nvm use 14.15.1
This command activates the specified version of Node.js and sets it as the default version for the current terminal session. You can verify the currently activated version of Node.js by running the same node -v command again.
You can also install multiple versions of Node.js using NVM and switch between them as required. This feature is useful when working on projects that require different versions of Node.js.
Step 5: Update Node.js
NVM allows you to keep your Node.js installations up-to-date by updating to the latest version. To update to the latest version of Node.js using NVM, you can use the following command:
nvm install node --reinstall-packages-from=node
This command installs the latest version of Node.js and also reinstalls all the packages and dependencies associated with the previous version of Node.js.
Conclusion
Updating Node.js on Ubuntu 18.04 is straightforward, thanks to Node Version Manager (NVM). NVM simplifies the installation and management of Node.js on your system, making it easier to work on projects with different dependencies. By following these steps, you can update, install, switch, and manage multiple versions of Node.js on your Ubuntu 18.04 system.
