Downgrading to a previous version of Node.js can be necessary for various reasons, such as compatibility issues with certain modules or libraries. This guide will walk you through the steps to downgrade your Node.js version on different operating systems.
1. Using Node Version Manager (NVM)
If you have Node Version Manager (NVM) installed, you can easily switch between different Node.js versions. Follow the steps below to downgrade to a previous version:
1. Open a terminal or command prompt.
2. Check the currently installed Node.js versions by running the following command:
nvm ls
3. Identify the version you want to switch to from the list.
4. Install the desired Node.js version by running the following command:
nvm install <version>
Replace <version> with the version number you want to install.
5. Switch to the installed version with the following command:
nvm use <version>
Again, replace <version> with the desired Node.js version.
6. Verify that you have successfully switched to the desired version by running:
node -v

2. Manual Installation
If you don’t have NVM installed, you can manually downgrade your Node.js version using the official Node.js installer. Follow the steps below based on your operating system:
2.1. Windows
1. Visit the official Node.js website (https://nodejs.org) and navigate to the “Downloads” page.
2. Scroll down to the “Previous Releases” section.
3. Find the version you want to install and click on the corresponding “Windows Installer” link.
4. Once the installer is downloaded, run it and follow the on-screen instructions.
5. After installation, open a new command prompt and verify the installed version by running:
node -v
2.2. macOS
1. Visit the official Node.js website (https://nodejs.org) and navigate to the “Downloads” page.
2. Scroll down to the “Previous Releases” section.
3. Find the version you want to install and click on the corresponding “macOS Installer” link.
4. Once the installer is downloaded, run it and follow the on-screen instructions.
5. After installation, open a new terminal window and verify the installed version by running:
node -v
2.3. Linux
1. Open a terminal and run the following command to remove the existing Node.js installation:
sudo apt-get remove nodejs
2. Visit the official Node.js website (https://nodejs.org) and navigate to the “Downloads” page.
3. Scroll down to the “Previous Releases” section.
4. Find the version you want to install and click on the corresponding “Linux Binaries” link.
5. Download the appropriate binary for your Linux distribution.
6. Extract the downloaded archive.
7. Rename the extracted folder (e.g., node-vX.X.X) to a desired name (e.g., node).
8. Move the renamed folder to a suitable location (e.g., /opt/node).
9. Open a terminal and run the following command to create a symbolic link:
sudo ln -s /opt/node/bin/node /usr/local/bin/node
10. Verify the installed version by running:
node -v
Additional Tips and Best Practices
– It’s generally recommended to use the latest stable version of Node.js to benefit from the latest features, improvements, and security patches. Downgrading should be done cautiously and only when necessary.
– Before downgrading, it’s a good practice to check if the specific issue you are facing can be resolved by updating your dependencies or using alternative libraries or modules.
– Keep track of the Node.js versions used in your projects by specifying the desired version in the package.json file. This ensures that everyone working on the project uses the same version, preventing potential compatibility issues.
– If you frequently switch between different Node.js versions, consider using Node Version Manager (NVM) to simplify the process.
