3、安装LTS版本

[root@localhost ~]# n lts
      installing : node-v14.15.4
           mkdir : /usr/local/n/versions/node/14.15.4
           fetch : https://nodejs.org/dist/v14.15.4/node-v14.15.4-linux-x64.tar.xz
       installed : v14.15.4 (with npm 6.14.10)
    
    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"
    [root@localhost ~]#

4、编辑环境变量：vim ~/.bash\_profile

# .bash_profile
    
    # Get the aliases and functions
    if [ -f ~/.bashrc ]; then
            . ~/.bashrc
    fi
    
    # User specific environment and startup programs
    
    PATH=/usr/local/bin/node:$PATH:$HOME/bin
    
    export PATH

5、刷新配置

[root@localhost ~]# source ~/.bash_profile
    [root@localhost ~]# node -v
    v14.15.4
