If you want to check the version of Node.js installed on a Mac system, follow the steps outlined below. This is important if you are working with server side Javascript and want to know the exact version of Node.js that you have on your Mac system. This article will give you step by step instructions to check the version of Node.js installed on your Mac.
Using a Node Version Manager. There are a lot of different versions of Node out there. These tools will help you keep track of what version you are using, and also make it easy to install new versions and switch between them. They also make npm easier to set up:) OSX. Jul 03, 2019. Aug 19, 2020.
Switch Node Version Mac
STEP 1: Open the terminal window on your mac system as shown below. Terminal is an appilcation on the Mac system. We can use the ‘node -v” command on the terminal to check the version of Node.js installed on Mac OS.
STEP 2: Enter the command ‘node -v’ without the quotes on the Mac terminal window as shown below.
STEP 3: Press the enter key to display the current version of Node.js installed on your Mac system as shown below. Note the version 8.4.0 displayed in the screenshot below. This is the current version of Node.js.
You now know the version of Node.js available on your Mac system. You can decide if you need to update the same. This is the simplest way to check the version of Node.js installed on Mac OS.
If is you get any other message stating that node is not a recognized command, then it implies that Node.js is not installed on your system. This is because the node command used above works only if Node.js is installed. It is not a standard terminal command. The failure of the system to recognize the node command implies Node.js is not installed on your system.

-->The following is a step-by-step guide to get you started using Node.js in a native Windows development environment.
Install nvm-windows, node.js, and npm
There are multiple ways to install Node.js. We recommend using a version manager as versions change very quickly. You will likely need to switch between multiple versions based on the needs of different projects you're working on. Node Version Manager, more commonly called nvm, is the most popular way to install multiple versions of Node.js, but is only available for Mac/Linux and not supported on Windows. Instead, we will walk through the steps to install nvm-windows and then use it to install Node.js and Node Package Manager (npm). There are alternative version managers to consider as well covered in the next section.
Important
It is always recommended to remove any existing installations of Node.js or npm from your operating system before installing a version manager as the different types of installation can lead to strange and confusing conflicts. This includes deleting any existing nodejs installation directories (e.g., 'C:Program Filesnodejs') that might remain. NVM's generated symlink will not overwrite an existing (even empty) installation directory. For help with removing previous installations, see How to completely remove node.js from Windows.)
Open the windows-nvm repository in your internet browser and select the Download Now link.
Download the nvm-setup.zip file for the most recent release.
Once downloaded, open the zip file, then open the nvm-setup.exe file.
The Setup-NVM-for-Windows installation wizard will walk you through the setup steps, including choosing the directory where both nvm-windows and Node.js will be installed.
Once the installation is complete. Open PowerShell and try using windows-nvm to list which versions of Node are currently installed (should be none at this point):
nvm lsInstall the current release of Node.js (for testing the newest feature improvements, but more likely to have issues than the LTS version):
nvm install latestInstall the latest stable LTS release of Node.js (recommended) by first looking up what the current LTS version number is with:
nvm list available, then installing the LTS version number with:nvm install <version>(replacing<version>with the number, ie:nvm install 12.14.0).List what versions of Node are installed:
nvm ls...now you should see the two versions that you just installed listed.After installing the Node.js version numbers you need, select the version that you would like to use by entering:
nvm use <version>(replacing<version>with the number, ie:nvm use 12.9.0).To change the version of Node.js you would like to use for a project, create a new project directory
mkdir NodeTest, and enter the directorycd NodeTest, then enternvm use <version>replacing<version>with the version number you'd like to use (ie v10.16.3`).Verify which version of npm is installed with:
npm --version, this version number will automatically change to whichever npm version is associated with your current version of Node.js.
Alternative version managers
While windows-nvm is currently the most popular version manager for node, there are alternatives to consider:
nvs (Node Version Switcher) is a cross-platform
nvmalternative with the ability to integrate with VS Code.Volta is a new version manager from the LinkedIn team that claims improved speed and cross-platform support.
To install Volta as your version manager (rather than windows-nvm), go to the Windows Installation section of their Getting Started guide, then download and run their Windows installer, following the setup instructions.
Important
You must ensure that Developer Mode is enabled on your Windows machine before installing Volta.
To learn more about using Volta to install multiple versions of Node.js on Windows, see the Volta Docs.
Install your favorite code editor
We recommend you install VS Code, as well as the Node.js Extension Pack, for developing with Node.js on Windows. Install them all or pick and choose which seem the most useful to you.
To install the Node.js extension pack:
- Open the Extensions window (Ctrl+Shift+X) in VS Code.
- In the search box at the top of the Extensions window, enter: 'Node Extension Pack' (or the name of whatever extension you are looking for).
- Select Install. Once installed, your extension will appear in the 'Enabled' folder of your Extensions window. You can disable, uninstall, or configure settings by selecting the gear icon next to the description of your new extension.
A few additional extensions you may want to consider include:
- Debugger for Chrome: Once you finish developing on the server side with Node.js, you'll need to develop and test the client side. This extension integrates your VS Code editor with your Chrome browser debugging service, making things a bit more efficient.
- Keymaps from other editors: These extensions can help your environment feel right at home if you're transitioning from another text editor (like Atom, Sublime, Vim, eMacs, Notepad++, etc).
- Settings Sync: Enables you to synchronize your VS Code settings across different installations using GitHub. If you work on different machines, this helps keep your environment consistent across them.
Install Git (optional)
Node Version Manager Download Mac Os
If you plan to collaborate with others, or host your project on an open-source site (like GitHub), VS Code supports version control with Git. The Source Control tab in VS Code tracks all of your changes and has common Git commands (add, commit, push, pull) built right into the UI. You first need to install Git to power the Source Control panel.
Download and install Git for Windows from the git-scm website.
An Install Wizard is included that will ask you a series of questions about settings for your Git installation. We recommend using all of the default settings, unless you have a specific reason for changing something.
If you've never worked with Git before, GitHub Guides can help you get started.
We recommend adding a .gitignore file to your Node projects. Here is GitHub's default gitignore template for Node.js.
Use Windows Subsystem for Linux for production
Using Node.js directly on Windows is great for learning and experimenting with what you can do. Once you are ready to build production-ready web apps, which are typically deployed to a Linux-based server, we recommend using Windows Subsystem for Linux version 2 (WSL 2) for developing Node.js web apps. Many Node.js packages and frameworks are created with a *nix environment in mind and most Node.js apps are deployed on Linux, so developing on WSL ensures consistency between your development and production environments. To set up a WSL dev environment, see Set up your Node.js development environment with WSL 2.
Note
If you are in the (somewhat rare) situation of needing to host a Node.js app on a Windows server, the most common scenario seems to be using a reverse proxy. There are two ways to do this: 1) using iisnode or directly. We do not maintain these resources and recommend using Linux servers to host your Node.js apps.
