'Error while compiling css and js files using gulp

I am getting the below mentioned error and I am not able to figure out how to handle it. Versions of gulp, node and npm are mentioned below. I don't know if it is node's version mismatch with that of gulp or something else but so far any help would be much appreciated.

gulp -v
CLI Version: 2.3.0
Local Version: 3.9.1

node -v
v6.10.3

npm -v
3.10.10

ERROR

Solution 1:[1]

Support for async functions was added in Node 7.6.0.

You are using Node 6.10.3.

You need to upgrade.

The oldest version of Node which is still supported (although only for a matter of weeks!) is version 12.

Upgrade to at least version 16.14.2 (the current long term support release).

Solution 2:[2]

install version 8.11.1 and run :

npm install
npm install gulp bower --global
            
npm install node-sass@latest
npm uninstall laravel-elixir
npm uninstall session
npm install --save laravel-elixir
npm install --save session
gulp

after that it will work
