Laravel - Installation Request for Guzzle/guzzle - Solved

When i was working on my updated ubuntu version, i did fetch this problem. I had ubuntu 14.04 then i updated ubuntu 16.04, at that time i think PHP version also updated PHP 5 from PHP 7.

Ubuntu 16 updated successfully but when i was trying to composer install or update on my project i was found guzzle package error and to enable extensions php 7 extensions as like bellow:

Error

Problem 1

You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

But at last i found what was the error and how to solve. I need to install curl and then php-curl on my ubuntu system like as bellow:

sudo apt-get install curl
sudo apt-get update
sudo apt-get install php-curl php-gd php-mbstring php-mcrypt php-xml php-xmlrpc

You can try and solve your issue....
