1. What is nvm?
nvm is a node version management tool, which can easily switch, install and view node versions. . . Wait, unlike npm, npm is a management tool for dependent packages.

Before installing, you need to uninstall the node on your computer!!!! Very important

Unzip the nvm-setup.zip installation package, enter the unzipped folder, double-click the exe suffix file to install
This interface is to choose the path to install nvm. You can change the installation path by yourself. Generally, the default path
This is the node installation location. The default is fine. The node folder will be automatically generated.
After the installation is complete, enter nvm -v to view the version.
3. The use of nvm
After the installation is complete, find the installation path, some simple configuration, and open the setting.txt (it will automatically generate npm for you after the download is complete, and you don’t need to install npm repeatedly after downloading the node package)
