how to install nvm in ubuntu 18 04 with code examples

Installing Node Version Manager (nvm) on Ubuntu 18.04 is a simple process that allows you to easily manage multiple versions of Node.js on your system.

First, you'll need to make sure that you have the necessary dependencies installed. Open a terminal and run the following command to install the required packages:

sudo apt-get update && sudo apt-get install build-essential libssl-dev

Next, you can install nvm by running the following command:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.35.3/install.sh | bash

This will download and run the installation script for nvm.

Once the installation is complete, you'll need to reload your shell by running the following command:

source ~/.bashrc

You can now use nvm to install the latest version of Node.js with the following command:

nvm install node

You can also install a specific version of Node.js by specifying the version number, like so:

nvm install 12.14.1

To switch between different versions of Node.js, you can use the following command:

nvm use 12.14.1

You can also set a default version of Node.js to be used when you open new terminal windows:

nvm alias default 12.14.1

You can check the version of Node.js that is currently in use by running the following command:

node -v

You can also list all the version of Node.js that you have installed with the following command:

nvm ls

That's it! With nvm installed on your Ubuntu 18.04 system, you can easily manage multiple versions of Node.js and switch between them as needed.

It is important to note that nvm is a script-based tool which means you have to run the above commands in your terminal, and also that, the version of nvm might be different from the one used in the examples. You can check the latest version of nvm in the official website.

In addition to managing multiple versions of Node.js, nvm also provides some other useful features that can be helpful when working with Node.js projects.

One such feature is the ability to manage multiple Node.js environments. With nvm, you can easily create separate environments for different projects, each with its own version of Node.js and npm packages. This can be especially useful for projects that have different version dependencies or when you want to test your code with different versions of Node.js.

Another useful feature provided by nvm is the ability to manage global npm packages. With nvm, you can easily install and manage global npm packages for each version of Node.js that you have installed. This can be helpful when you want to use a specific version of a global package for a particular project or when you want to ensure that your global packages are compatible with the version of Node.js that you are using.

nvm also provides a simple way to update Node.js and npm packages to the latest version. With the nvm command, you can easily update the version of Node.js and npm packages you are currently using to the latest version with a single command. This can be helpful when you want to take advantage of the latest features and bug fixes in Node.js and npm packages.

Additionally, nvm also allows you to uninstall Node.js versions easily. You can use the command nvm uninstall <version> to remove a specific version of Node.js from your system.

In summary, nvm is a powerful tool that provides a simple and efficient way to manage multiple versions of Node.js and npm packages on your Ubuntu 18.04 system. With nvm, you can easily switch between different versions of Node.js, create separate environments for different projects, manage global npm packages, update Node.js and npm packages to the latest version, and uninstall versions of Node.js you no longer need. With nvm, you can be sure that you have the right version of Node.js for your project and that you are able to take advantage of the latest features and bug fixes.
