How to Change Node Version with NVM (and Set Default)

Introduction

Node Version Manager (NVM) is a popular tool among developers for managing multiple Node.js versions. It provides the flexibility to switch between Node versions as needed for various projects. In this post, we’ll explore how to effectively use NVM to set a default Node version and change between Node versions, targeting the key phrases “NVM set default node version” and “change node version.”

Node.js’s versatility and version variability can be both a boon and a challenge. For instance, different projects may require different Node versions due to dependency requirements or compatibility issues. Managing these versions efficiently is crucial to maintain productivity and ensure seamless project execution.

Key Takeaways

• Setting a default Node version ensures consistency across projects and sessions.
• Use nvm use <version_number> to switch to a specific version of node.
• Use nvm alias default <version_number> to specify a default version of node.

Setting a Default Node Version with NVM

Setting a default Node version means that every new terminal session will automatically use this specified version, saving time and reducing the risk of version inconsistency issues. Here’s how you can set a default Node version with NVM:

Install NVM:

• Before setting a default Node version, ensure that NVM is installed on your system. You can find installation instructions on the NVM GitHub page.

List Available Node Versions:

• Run nvm list in your terminal to see the installed Node versions.

Set a Default Version:

• Use nvm alias default <version_number> to set your preferred version as the default. For example, nvm alias default 14.17.0.

How to Change Node Versions with NVM

Changing Node versions is a frequent task, especially when working on multiple projects. NVM simplifies this process:

1. Check Current Version:

   • Run nvm current to see which Node version is currently active.

2. Switch Node Versions:

   • To change the Node version, use nvm use <version_number>. For example, nvm use 12.18.3 will switch to version 12.18.3.

Conclusion

NVM is a powerful tool that simplifies the management of multiple Node.js versions. By setting a default Node version, you ensure a consistent development environment across all projects. Additionally, the ability to change Node versions easily facilitates testing and development across different Node environments.
