Prerequisites
To follow this tutorial successfully, you’ll need the following:
- Internet access to download Node.js.
- Basic knowledge of how to use the terminal.
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:
- It allows you to install multiple versions of Node.js.
- It makes it easy to switch between the versions.
- Updating node.js is a breeze with nvm.
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.Download super mario world for mac. 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.Tip: On Mac, if you are having any issues with the
nvm
command not working, check out this linkLets now install Node using nvm’s install command.
Once installed, set the installed version as the default.
Info: https://tribalbrown484.weebly.com/blog/download-arena-elder-scrolls-on-mac. You need to set the default version because nvm forgets the node version in a new terminal session. You can learn more about the issue here.
Step 2 — Verify Node.js and npm installation

. 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
- Running Node.js scripts on the terminal
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
