The Challenge of Checking If Nodejs Is Installed on Mac
Most of the time, when a developer starts working with Nodejs on a Mac, they assume that Nodejs is already installed on their system. However, this isn’t always the case. Having Nodejs pre-installed on a Mac depends on the version of macOS you are using. If you have an older version of macOS, you may have to manually install Nodejs.
While it may seem like a simple task to check if Nodejs is installed on your Mac, it can be challenging for beginners. Without understanding the steps involved, it can be easy to overlook certain details in the installation process, which can result in errors when running your code.
Things You Should Prepare for
Before checking if Nodejs is installed on your Mac, there are a few things you should prepare for. These include:
- Knowing which version of macOS you are running
- Having admin privileges on your Mac to install Nodejs, if it isn’t already installed
- Having a reliable internet connection to download Nodejs, if you need to install it
Method 1: Checking Nodejs Version via Terminal
One of the easiest ways to check if Nodejs is installed on your Mac is to use the Terminal app. Here’s how:
1. Open the Terminal app on your Mac by searching for it using Spotlight (CMD + Space).
2. In the Terminal app, type the following command:
"`
node -v
"`
This command will display the version of Nodejs that is installed on your Mac.
Pros:
- Quick and easy way to check if Nodejs is installed
- Provides information about the version of Nodejs installed on your Mac
Cons:
- This method only works if Nodejs is already installed on your Mac
Method 2: Checking the Applications Folder
Another way to check if Nodejs is installed on your Mac is to look for it in the Applications folder. Here’s how:
1. Click on the Finder app in the Dock.
2. Select the Applications folder from the left-hand sidebar.
3. Scroll down the list of applications and look for the Nodejs icon.
4. If you see the Nodejs icon, it means that Nodejs is already installed on your Mac.
Pros:
- Easy way to check if Nodejs is installed on your Mac
Cons:
- If Nodejs isn’t installed, this method does not provide any guidance on how to install it
Method 3: Checking the Bash Profile
Another way to check if Nodejs is installed on your Mac is to check the Bash profile. Here’s how:
1. Open Terminal and type the following command:
"`
ls -a ~/
"`
2. This should output all the files in your home folder. Look for the .bash_profile file.
3. If you found the .bash_profile file, open it in a text editor and look for a line that contains the following:
"`
export PATH="/usr/local/bin:$PATH"
"`
4. If this line is present, it means that Nodejs is already installed on your Mac.
Pros:
- Provides additional information about the Bash profile and how it affects Nodejs installation
Cons:
- This method is not suitable for beginners
- Might be challenging to locate the .bash_profile file
Why Can’t I Find Nodejs on My Mac?

Fix: You need to follow the steps to install Nodejs on your Mac, which you can find on the official Nodejs website.
2. You may have overlooked Nodejs when looking for it in the Applications folder.
Fix: Double-check the Applications folder, or use a different method to check if Nodejs is installed.
3. The .bash_profile file is not present in your home folder.
Fix: Create a new .bash_profile file and add the following line:
"`
export PATH="/usr/local/bin:$PATH"
"`
4. The command you are using to check for Nodejs is incorrect.
