How does Node.js perform version management? 3 practical version management tools to share

NodeHow to perform version management? The following article will share with you 3 very practical Node.js version management tools. I hope it will be helpful to you!

In the previous article "What are the differences between various versions of Node.js? How to choose the right version?" introduced that Node.js versions are divided into LTS and Current series. When we need to install both the LTS version and the Current version in the local development environment, we need to perform version management on the Node.js version.

For example, Node.js 8.0.0 and Node.js 17.0.0 need to be installed locally.

In order to be able to version manage theNode.jsversion, I have compiled 3 very practical Node.js version management tools, allowing everyone to freely switch to Node in different local environments. js version.
