As with any programming language, platform, or tool, the first step to using it is getting it installed. Many of them typically come with a speedy way to upgrade when a new version is available.

\n

By default, there's not a way to upgrade the version of Node.js you've got from within Node.js itself. That said, there's a fantastic tool for the community called nvm that allows you to manage the versions of Node.js that you've got installed locally.

\n

One awesome aspect of nvm is that it manages the versions of Node.js, it doesn't just upgrade them. This means you can have the latest version of Node.js, the latest versions of all the LTS release lines, and any number of other versions you want to use or test as well.

\n

In this quick tutorial, we'll take a look at how to install nvm, and then how to start using it as your version manager for Node.js. Once we've completed the tutorial, you'll be ready to take the next step with Node.js.

\n

This guide covers installing nvm on macOS and Linux - note that all versions of Node.js may not support every version of macOS or Linux.

\n

Step 0: The Quick Guide (TL;DR) to Get Node.js Installed using nvm

\n

Here's the abbreviated guide, highlighting the major steps:

\n\n

Step 1 (Optional): Ensure your system has the appropriate C++ compiler

\n

In some cases, like when installing Node.js releases from their source or installing versions of Node.js before 0.8.6 (when the project started shipping binaries), you'll need to ensure that your system has the appropriate C++ build tools.

\n

For LTS and modern releases, you will not need this step. That said, it's a nice to have to ensure that the majority of requirements are met in any scenario.

\n

On macOS, you've got two options for a C++ compiler: the full XCode application or the stand-alone Command Line Tools portion of Xcode.

\n

To get these on macOS, you can follow these steps:

\n\n

On Linux, the C++ compiler will vary from distribution to distribution. For example, on Debian and Ubuntu, you'll need to install build-tools and libssl-dev, but this may be different on your given Linux distribution.

\n

To get build-tools and libssl-dev on Debuan and Ubuntu distributions, you can run these commands:

\n
sudo apt-get install build-essential # Install the build-essential package - let this run to completion\n\nsudo apt-get install libssl-dev # Install the libssl-dev package - also let this one run to completion\n
\n

Step 2: Download nvm with the install script

\n

Once you've got the right C++ compiler for your system, now it's time to run the nvm install script. Here are the single-step install scripts for both macOS and Linux. You've got the option of cURL or Wget but both achieve the same result.

\n

Note: If your Linux system doesn't have either cURL or Wget, you can run sudo apt-get install curl and use the cURL method.

\n

Running the Install Script with cURL:

\n

To install nvm with the cURL method, run the following command in your terminal:

\n
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash\n
\n

Using the Install Script with Wget:

\n

To install nvm with the Wget method, run the following command in your terminal:

\n
wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash\n
\n

Step 3: Verify that nvm was Properly installed

\n

After running the install script from Step 2, nvm should have successfully installed. To ensure that nvm is up and running on your machine, you can test it with the following command:

\n
nvm --version\n
\n

This command will return something like (though not necessarily exactly) the following:

\n
nvm --version # The command we ran - it checks the currently installed version of nvm\n0.33.0 # The current version of nvm - yours may differ!\n
\n

Missing the nvm command after running the install script?

\n

If you're using macOS, you may be missing a .bash_profile file - to troubleshoot this, you can run touch ~/.bash_profile in your command line and re-run the installer script.

\n

If the problem persists after that, you can open the existing .bash_profile file (using your favorite text editor) and add the following line to it:

\n
source ~/.bashrc\n
\n

If you're still having issues, you can take a peek at this issue to find a discussion of the problem and a collection of possible resolutions.

\n

Step 3: Using nvm to manage Node.js

\n

Congratulations! You've now got nvm - a tool to easily allow you to manage and swap out the versions of Node.js you've got installed locally. Now, let's get you started with doing just that.

\n

Install the latest Node.js version

\n

To install the latest available version of Node.js, you can use the following command:

\n
nvm install node\n
\n

Next, to use that version of Node.js in any new shell, you can simply run the use command:

\n
nvm use node\n
\n

Install the latest Node.js LTS version

\n

To install the latest available LTS version of Node.js, you can run the following command:

\n
nvm install --lts\n
\n

And to use that latatestTS version of Node.js in any new shell, you can simply run the use command:

\n
nvm use --lts\n
\n

Step 6: Go build applications, APIs, tools, and more with Node.js!

\n

Now you've got a fantastic version manager for Node.js. It's time to start building!
