How to Fix 'command not found: nvm' After Installing nvm

Introduction

When you install NVM (Node Version Manager) and find that your terminal still can't locate it, this error message command not found: nvm will show up. This tutorial will guide you through the process of resolving this issue.

Why You Might Get This Error

The NPM package manager has installed a version of Node.js on your machine without telling the shell (Terminal) that it's there. As a result, when you try to run a command for which NVM is needed, like nvm, the shell can't find it.

Troubleshooting Steps

This section outlines the steps to fix this issue.

1. Check Your Installation:

Ensure your installation of nvm and node are up-to-date.

$ npm install -g nvm

1. Reinstall Node.js:

Sometimes, reinstalling can fix issues with package managers not recognizing installed software correctly.

$ rm -rf ~/.nvm

$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

$ . $(brew --prefix nvm)/bin/nvm.sh

$ nvm install node

1. Verify Node.js Installation:

Ensure you are using the correct version of Node.js.

$ node -v

v18.19.1

$ npm -v

9.2.0

1. Check Your Shell Configuration File (~/.zshrc, ~/.bashrc, etc.):

Sometimes changes in your shell configuration file might cause issues with package installation paths. Replacing the path to Node.js in this file will help.

1. Reinstall nvm:

If you want to completely remove and reinstall nvm:

$ rm -rf ~/.nvm

$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

$ . $(brew --prefix nvm)/bin/nvm.sh

1. Install Node.js via nvm:

If you want to use nvm exclusively, make sure to install it this way.

Real Commands

Step 1: Check Installation:

$ npm -v

9.2.0

Step 2: Reinstall Node.js:

$ rm -rf ~/.nvm

$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

$ . $(brew --prefix nvm)/bin/nvm.sh

$ nvm install node

Step 3: Verify Installation:

$ node -v

v18.19.1

$ npm -v

9.2.0

Quick Answer

To fix 'command not found: nvm' after installing nvm, make sure you have installed nvm globally using npm install -g nvm. Then, re-install your preferred version of node via nvm install node.

Common Mistakes and Troubleshooting
