Install nvm under linux to quickly switch node versions

nvm (Node Version Manager) is a Nodejs version manager that can quickly switch between different node versions.

Why use NVM?

There are more and more node-based tools and projects, but the node version used by each project may be inconsistent, and some strange problems will occur. For example: The latest version of node is installed on your computer, but the project you take over uses a lower version of node. Then I can only switch to a lower version of node and perform the operation without error. NVM is used to help us quickly switch node versions.
