nvm installation and use

nvm install

It is recommended to use the nvm-setup installation version, which is free of configuration.
Just download the installation package and install it in a fool-like way;
open CMD, enter the command nvm, and the installation is successful, as shown below. You can see that there are various commands listed in it.

install/manage nodejs

1. Install the node command (when installing, npm will be installed automatically)

	nvm install  <version>  // version是版本号 	
		例如 ：  nvm install 14.11.0

2. Switch node version

	nvm use  <version>   //切换到使用指定的nodejs版本
		例如 ：  nvm use 14.11.0

3. Uninstall the node version

	nvm uninstall<version>   //卸载指定的nodejs版本
		例如 ：  nvm uninstall 14.11.0
