cURL错误60：Laravel 5.3中的SSL证书

I'm trying to build a social media package socialite version ^2.0 login in Laravel 5.3, where I've configured as per the instruction on github, while getting the callback I'm getting an error:

cURL error 60: SSL certificate problem

Well I tried searching about this problem and whatever it was instructed I did, but still getting the same certificate error.

First of all I'm using wamp server which has PHP version 5.6 and 7 I saved the cacert.pem from the link https://curl.haxx.se/ca/cacert.pem and placed it to C:\wamp\bin\php\php7.0.4\ext and to C:\wamp\bin\php\php5.6.19\ext and edited php.ini file of respective version and added the following at end of the file:

[cURL]
curl.cainfo="C:\wamp\bin\php\php7.0.4\ext\cacert.pem"

and

[cURL]
curl.cainfo="C:\wamp\bin\php\php5.6.19\ext\cacert.pem"

Well this didn't worked so I searched more I came to know that I need to install guzzlehttp/guzzle So I did so, while using the version ^6.0 I was still getting the same then I tried version ^4.0 as it was suggested in many blogs, while doing so I was getting a bindshared error:

  Symfony\Component\Debug\Exception\FatalErrorException]
Call to undefined method Illuminate\Foundation\Application::bindShared()

And it resisted the socialite function to execute. While trying the version 5.0 I was getting this error:

cURL error 60: SSL certificate problem: unable to get local issuer certificate

I tried disabling the firewall too, but same thing are displaying. Guide me in this. Currently I'm working on PHP Version 7.0.4
