Installing and working with Node, npm, nvm on MacOS

How to Install macOS Catalina from Bootable Installer. Insert the Bootable Installer to your MAC. Restart your Mac. Power to the Mac and hold on to the Options button on the keyboard. Select the macOS Catalina alternative from the drop-down menu. Then, the utility window will be opened, you have to pick the disk drive utility.

You can install node (which installs npm and npx along with it) either by

Directly obtaining an installer from: https://nodejs.org/en/download/
With the brew package manager (see below).

One of the easiest ways to do this on MacOS is via the brew package manager.

Installing `brew`

To install brew, visit https://brew.sh and follow the instructions
Before installing anything with brew, it’s good practice to run brew update first.
If your brew install is messed up, brew doctor can help restore a proper install.

Using `brew` to install node

This command will install node using brew

To test if it worked, you can try:

If you get an error like this one when you try to do npm install, then you may need to reinstall your XCode tools.

Here are the instructions for doing so:

- NOTE however that there is a missing step in those instructions. After removing the old version of the XCode command line tools, to start theprocess of reinstalling the XCode command line tools, type git at the command prompt.

If that doesn’t work, here’s another option:

This worked for me.

Install full Xcode Open Xcode and the CLT will install Then run sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

This uses the full Xcode CLT and node-gyp works.

These instructions work for Linux too.

Most node tutorials suggest installing node and then using the tool npm.

It’s probably a better idea to work with nvm if you are using your own computer, as that will allow you to maintain separate node environments fordifferent projects.

Using the cURL command

One of the simplest ways to install NVM is to run the following cURL command in your terminal:

What does the command actually do?

It downloads the nvm script from GitHub, and then it runs it.
After that, it also clones the nvm repository to /Users/yourMacUsername/.nvm.
Lastly, it adds a script to your profile file (~/.bash_profile, or ~/.zshrc, or ~/.profile, or ~/.bashrc) to enable you to use the nvm command in your terminal.

All you have to do now is restart your terminal, and you can use the Node Version Manager. Alternatively, if you do not want to restart your terminal after running the cURL command, run source ~/.nvm/nvm.sh in your terminal. Afterward, you can run the nvm commands straightaway.

Using Homebrew

Another method is to install the Node Version Manager with Homebrew. Run the below command in your terminal:

After the installation finishes, open your profile file (~/.bash_profile, or ~/.zshrc, or ~/.profile, or ~/.bashrc), and add the following lines to it at the end:

By adding the above lines to your profile page, you can run the nvm command in your terminal. If you don't add the above lines, you will get an error when you run nvm commands in the terminal. Going further, you need to restart your terminal to use the nvm commands in the terminal.

NVM commands

Now that you have NVM installed, let's see some of the most useful commands.

nvm ls-remote

First of all, we can run nvm ls-remote to find all the Node versions available for download. Caution: by running this command, you'll get a lot of versions.

Thus, it might take a while until it finishes.

nvm install

After running the command nvm ls-remote, we can install the version we want by running the following command:

For instance, if you want to install Node version 14, you need to run nvm install 14. It installs the latest Node 14 version. However, if you're going to install a particular version, you can specify it as follows - 13.10.1.

Tip: You can install the latest LTS version of Node by running nvm install --lts.

nvm ls

nvm ls lists all the Node versions installed on your machine. Don't confuse nvm ls with nvm ls-remote. The former one lists the ones installed on your machine, whereas the 'ls-remote' lists all the Node versions available for download.
