Changing the Node version on your system typically involves using a version manager. This allows you to switch between different versions for various projects. Below are the steps using two popular version managers: Node Version Manager (NVM) and Node (n). Before proceeding, ensure you have command-line/terminal access.
Using Node Version Manager (NVM)
1. Install NVM:
- Open your terminal.
- Install NVM by running the install script:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash- Restart your terminal or run
source ~/.nvm/nvm.shto start using it immediately.
2. Install the Node version you need:
- List all available versions:
nvm list-remote- Install a specific version of Node:
nvm install 14.17.0 # replace with your preferred version3. Switch between installed Node versions:
- Use the following command to switch:
nvm use 14.17.0 # replace with the version you want to use4. Set a default Node version:
Set a version to default so it’s used in any new shell:
nvm alias default 14.17.0 # replace with your preferred versionUsing Node (n)
1. Install Node (n):
- Node (n) can be installed via npm:
npm install -g n2. Change Node version:
Install and use the latest version:
n latestOr install and use a specific version:
n 14.17.03. Switch between versions:
- Once installed, switch between the installed versions using:
n- Then select the version you want to switch to using the arrow keys and Enter.
Tips and Troubleshooting:
- Restart your terminal: After installing a new Node version, you may need to open a new terminal window or tab to use it.
- Check the version: You can always check the current Node version by running
node -v. - Permissions: If you encounter permissions errors, you might need to run the install commands with
sudo(for macOS/Linux) or run your command prompt as an administrator (for Windows). - Compatibility: Ensure any global npm packages you have are compatible with the new Node version, or reinstall them as needed.
