If a version was output, then you're all set.
Introduction
Node.js is a run-time environment used for executing JavaScript outside the browser. Npm is a JavaScript package manager commonly used for installing packages for Node.js.
In this article, you will learn how to install Node.js and npm on Mac or Linux. You will also learn how to verify the installation, run Node.js code, and how to update Node.js and npm.
When you’re finished, you’ll be able to run Node.js code on Mac or Linux computer.

Step 1 — Install Node.js and npm on Mac or Linux
There are a couple of ways to install Node.js on Mac or Linux. The most recommended method and also my favorite method to install Node.js and npm is to use Node Version Manager(nvm).
Using nvm has the following benefits:
So let’s now install nvm. Copy and paste the command below into your terminal.
Info: If your on Mac, open your
~/.bash_profile or create a new one if the ~/.bash_profile file does not exist. Make sure you add source ~/.bashrc in the file and save.
Now let’s verify if
nvm was installed successfully.
Your terminal should display the current version of nvm. At the time of writing, the current version is 0.35.2. So this is the output I got.
Note: On Linux, if you get
nvm: command not found or no feedback, close your terminal and open a new terminal and enter the nvm --version again. If you using ssh to access linux, you might need to restart your session. Newton 2 after effects mac download.

Once installed, set the installed version as the default.
Info: You need to set the default version because nvm forgets the node version in a new terminal session. How to download photos from icloud on mac. You can learn more about the issue here.
Step 2 — Verify Node.js and npm installation
Verify if Node.js and npm were successfully installed.
Type
node -v . It will display the current Node.js version.
Type
npm -v to display the current npm version.
Your output should look similar to mine. Note that the versions will be different since you might be reading this tutorial when new versions came out.
Running Node.js Code on Mac or Linux
There are two ways to run Node.Js code:
Node.js REPL
REPL stands for Read-Evaluate-Print-Loops. It is an interactive shell that allows experimentation of JavaScript code. It works the same way as the web browser console.
To access the Node REPL, type
node in the terminal.
The REPL prompt will be opened where you can enter the JavaScript code.
The
> sign is there to let you know that the code entered will be immediately evaluated when you press enter.
To exit out of the REPL, type
.exit or press CTRL+D once. You can also exit out by pressing CTRL+C twice.
Running Node.js Scripts on the Terminal
This method is the one that is commonly used to run Node. You will write Node.js code in a file with an extension of
.js and run it in the terminal using the node command.
Let’s see this in action by creating a directory named
node.js in our home directory.
mkdir is a command used for creating directories
Let’s go into the
nodejs directory.
Your terminal should now show you are in the
node.js directory.
![]()
Create a file
first-program.js . For simplicity’s sake, we will use Nano which is a terminal text editor.
Enter the following code in
first-program.js in the Nano editor.
Hold CTRL+O and then press
enter to save the file.
Exit out of the editor by holding
CTRL+X .
Let’s now run the code in
