n lts Install the latest LTS node release (downloading if necessary)
n Install node (downloading if necessary)
n run [args …] Execute downloaded node with [args …]
n which Output path for downloaded node
n exec [args…] Execute command with modified PATH, so downloaded node and npm first
n rm <version …> Remove the given downloaded version(s)
n prune Remove all downloaded versions except the installed version
n --latest Output the latest node version available

3.6 升级node到稳定版

[root@localhost ~]# n stable

installing : node-v12.18.2
mkdir : /usr/local/n/versions/node/12.18.2
fetch : https://nodejs.org/dist/v12.18.2/node-v12.18.2-linux-x64.tar.xz
installed : v12.18.2 (with npm 6.14.5)

Note: the node command changed location and the old location may be remembered in your current shell.
old : /usr/bin/node
new : /usr/local/bin/node
To reset the command location hash either start a new shell, or execute PATH=“$PATH”
3.7、升级npm到最新

[root@localhost ~]# npm install -g npm
/usr/local/bin/npm -> /usr/local/lib/node_modules/npm/bin/npm-cli.js
/usr/local/bin/npx -> /usr/local/lib/node_modules/npm/bin/npx-cli.js
/usr/local/lib
└── npm@6.14.5
3.8、验证是否是最新稳定版

[root@localhost ~]# node -v
v12.18.2
[root@localhost ~]# npm -v
6.14.5
3.9、n工具指定node版本，命令打包编译

n exec 12 cnpm install

n：为指定使用的工具
exec：命令使用的方法
12：为node版本
cnpm：执行的工具
install：执行安装命令
