install nodejs
sudo apt-get install -y nodejs npmsudo npm config set registry https://registry.npm.taobao.orgsudo npm install n -gsudo n stable
n是一个Node工具包，它提供了几个升级命令参数：
n 显示已安装的Node版本n latest 安装最新版本Noden stable 安装最新稳定版Noden lts 安装最新长期维护版(lts)Noden根据提供的版本号安装Node
sudo n stable mkdir: /usr/local/n/versions/node/10.16.03download: wget https://nodejs.org/dist/v10.16.3/node-v10.16.3-linux-x64.tar.gzcp /usr/local/n/versions/node/10.16.03/lib No Such File or Directory
如果下载文件超时，无法进行升级 node，通过上面的信息，可以是下载 node-v10.16.3-linux-x64.tar.gz 文件
在 获取页面，进入到对应的文件夹下，看到列出的文件列表，找到名为node-v10.16.3-linux-x64.tar.gz 的链接，在Chrome浏览器下，可右键 -> 选择"复制链接地址"之后，进入到 终端
