Tutorial on using node version management tool n

1. Installation 

n is a nodejs management tool, https://github.com/tj/n

 npm install -g n

2. Use n to install the nodejs version

// 安装最新版本
n latest

// 安装指定版本13.11.0
n node/13.11.0

3. Switch nodejs version

n

Use the up and down arrow keys to select the installed version and press Enter to confirm.

 After the switch is successful, use the node -v command to view the current version. If the version number just selected is displayed, the switch is successful.

If it still doesn't work, you may need to set the PATH.
