安装最新版本的Nodejs

安装最新版本的Nodejs
==================

sudo apt-get install npm
sudo npm install npm@latest -g
sudo npm cache clean -f
sudo npm install -g n
sudo n latest

sudo ln -sf /usr/local/n/versions/node/<VERSION>/bin/node /usr/bin/nodejs

如果遇到以下问题

sudo npm install -g n 
/usr/local/lib/node_modules/npm/bin/npm-cli.js:79
      let notifier = require('update-notifier')({pkg})
      ^^^

SyntaxError: Block-scoped declarations (let, const, function, class) 
not yet supported outside strict mode
    at exports.runInThisContext (vm.js:53:16)
    at Module._compile (module.js:374:25)
    at Object.Module._extensions..js (module.js:417:10)
    at Module.load (module.js:344:32)
    at Function.Module._load (module.js:301:12)
    at Function.Module.runMain (module.js:442:10)
    at startup (node.js:136:18)
    at node.js:966:3

则只需要删除安装的npm

cd /usr/local/lib/node_modules
mv npm/ /tmp/usr_local_lib_node_modules_npm

然后重新执行

sudo npm install -g n 
sudo n stable
