preface

Most of today’s web front-end development is inseparable from Node, and Node updates iteration quickly; Different projects depend on different Node versions. Therefore, the node version must be installed to ensure proper operation. Maintaining multiple versions of Node at the same time can be a very troublesome thing, at this point we need a version control tool that can install multiple versions of node and can switch at any time to simplify our work, the commonly used node version management tools are N, NVM, NVS, here I mainly introduce NVM.

NVM is introduced

NVM is a nodeJS versioning tool. It lets you install and switch different versions of NodeJS. Download, install, and use are listed below.
