Downgrading Node Version: A Step-By-Step Guide To Revert To A Previous Node.Js Version

How to Downgrade Node Version: A Comprehensive Guide

Prerequisites for Downgrading Node Version:

Before proceeding with the steps to downgrade Node version, ensure that you have the following prerequisites in place:

1. Node Version Manager (NVM): This tool allows you to easily switch between different versions of Node on your system. It is recommended to have NVM installed, as it simplifies the process of downgrading Node.

2. Current Node Version: Check the current version of Node installed on your system. This will help in identifying the target version you wish to downgrade to.

Checking the Current Node Version:

To check the current Node version installed on your system, open your command prompt (Windows) or terminal (macOS or Linux) and execute the following command:

“`
node -v
“`

This will display the installed Node version.

Identifying the Target Node Version:

Before downgrading Node, it is essential to identify the target version. It can be a specific version like 16 or a more general version like 14.x. Having a clear target version will help you determine the steps required for the downgrade.

Now, let’s explore two different approaches to downgrade Node version using NVM and NVM Windows.

Step 2: List Available Node Versions:
– To list all available Node versions, use the command `nvm list available`.
– This will display a list of Node versions with their respective architectures and release dates.

Step 3: Install Target Node Version:
– Choose the target Node version you want to downgrade to from the available list in the previous step.
– Execute the command `nvm install ` replacing `` with the desired Node version (e.g., `nvm install 14.17.3`).
– NVM will download and install the specified Node version.

Step 4: Switch to the Downgraded Node Version:
– After installation, switch to the desired Node version by executing the command `nvm use `.
– Replace `` with the target version (e.g., `nvm use 14.17.3`).
– This will set the chosen Node version as the active version.

Troubleshooting Common Issues with Node Downgrading:

Here are some common issues that users may face when downgrading Node version and their possible solutions:

1. Permission Errors:
– If you encounter permission errors while installing or switching the Node version, try running the terminal or command prompt as an administrator.

2. NPM Compatibility:
– Downgrading the Node version may also require downgrading the NPM version to maintain compatibility. To do this, run the command `npm install -g npm@`, replacing `` with the desired NPM version.

3. Path Configuration Issues:
– Sometimes, after downgrading Node, the command prompt or terminal may still point to the old version. In such cases, update the PATH environment variable to point to the correct Node version.

How Can I Downgrade Node Version?

Node.js is an open-source, JavaScript runtime environment that allows developers to run JavaScript code on the server side. It offers a range of features and benefits, making it a popular choice among developers. However, there may be instances where you need to downgrade your Node.js version. This article will explain the various methods you can use to achieve this.

Before we dive into the steps, it’s essential to understand why you may find yourself needing to downgrade a Node version. One of the most common reasons is compatibility issues. Sometimes, new versions of Node might introduce changes that break your existing codebase or are not compatible with certain libraries or dependencies.

Another reason might be to match the exact version used in a production environment. In such cases, you’ll need to ensure your local development environment is aligned with the production setup to avoid any unexpected issues.

Without further ado, let’s explore the methods to downgrade your Node.js version.

1. Using Node Version Manager (NVM):
Node Version Manager, commonly known as NVM, is a handy tool that allows you to manage multiple Node.js versions on your machine. NVM makes downgrading Node.js version a breeze. Begin by installing NVM on your system as per the provided instructions. Once installed, open your command prompt or terminal and run the following command:

$ nvm install [version]

Replace [version] with the desired Node.js version you want to downgrade to. NVM will automatically install the specified version alongside your existing version, allowing you to switch between them easily.

2. Installing a Specific Version:
If you prefer not to use NVM, you can download the specific Node.js version you want from the official Node.js website. Locate the “Previous Releases” section on the download page and select the desired version. Once downloaded, run the installer and follow the installation instructions. This method will replace your existing Node version entirely with the version you downloaded.

3. Using Package Managers:
If you have Node.js installed using package managers like npm or yarn, you can leverage their capabilities to downgrade your Node.js version. These package managers also come with version management features.

To downgrade Node.js using npm, open your command prompt or terminal and run the following command:

$ npm install -g [email protected][version]

Replace [version] with the desired Node.js version you want to downgrade to. This command will install the specified version globally on your system.

For yarn users, execute the following command:

$ yarn global add [email protected][version]

Again, replace [version] with the specific Node.js version you want to downgrade to.

How to Downgrade Node Version on Mac: A Step-by-Step Guide

Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to build server-side and networking applications. It provides a rich collection of libraries and frameworks to streamline the development process. However, occasionally, you may need to downgrade your Node version on your Mac due to compatibility issues or project requirements. In this article, we will explore the steps involved in downgrading your Node version on a Mac, along with some frequently asked questions.

Before we begin, it is important to note that downgrading Node.js versions can have implications for your existing projects. Make sure to backup any important code or data before proceeding with the downgrade process.

Step 1: Check Your Current Node Version
First, check the version of Node.js installed on your machine before you proceed with the downgrade. Open the Terminal application on your Mac and type the following command:
“`
node -v
“`
This will display the current Node version you have installed.

Step 2: Uninstall the Current Node Version
To downgrade Node.js, you need to uninstall the current version from your system. One of the popular tools to manage Node.js installations is NVM (Node Version Manager). If you don’t have NVM installed, you can install it by following the instructions on the official NVM GitHub repository.

Once NVM is installed, you can use it to uninstall the current Node.js version by running the following commands in the Terminal:
“`
nvm ls
nvm uninstall
“`
Replace `` with the actual version of Node.js you want to uninstall. For example, if your current version is 12.22.2, you would run `nvm uninstall 12.22.2`. NVM will take care of removing the selected version from your system.

Step 3: Install the Desired Node Version
After successfully uninstalling the existing version, it’s time to install the desired Node version. In the Terminal, run the following command:
“`
nvm install
“`
Replace `` with the version of Node.js you want to install. For instance, if you want to install version 10.15.3, you would run `nvm install 10.15.3`. NVM will download and install the specified version on your Mac.

Step 4: Set the Default Node Version
To avoid conflicts and ensure that the desired Node version is used globally, you should set it as the default version. Run the following command in the Terminal:
“`
nvm alias default
“`
Again, replace `` with the version of Node.js that you just installed. This command will set the specified version as the default for your system.

Step 5: Verify the Downgraded Node Version
Restart your Terminal application and type `node -v` to check if the Node.js version has been successfully downgraded. If the displayed version matches the one you installed in Step 3, congratulations! You have successfully downgraded your Node version on your Mac.
