Setting up php-casperjs with composer - php

Question

I'm having trouble setting up php-casperjs for my project. I've never used composer before, so I'm not exactly sure what I'm doing wrong.
I got xampp installed on Windows with php version 5.6.12
Here are the steps I completed so far.
Downloaded and installed composer. It launches successfully from the command prompt.
Downloaded php-casperjs and extracted composer.json and src/Casper.php into my project folder C:\xampp\htdocs\test
Navigated to the project folder in the command prompt and ran composer install command which installed 22 packages
Then I ran composer require phpcasperjs/phpcasperjs command and here I ran into problems. I get the following error message
Using version ^1.2 for phpcasperjs/phpcasperjs
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
Problem 1
- The requested package phpcasperjs/phpcasperjs No version set (parsed as 1.0.0) is satisfiable by phpcasperjs/phpcasperjs[No version
set (parsed as 1.0.0)] but these conflict with your requirements or
minimum-stability.
Installation failed, reverting ./composer.json to its original
content.
When I run the following php code
use Browser\Casper;
$casper = new Casper();
I get Fatal error: Class 'Browser\Casper' not found in C:\xampp\htdocs\test\test.php on line 3

Step1: Go to you project directory and create a file "composer.json"
codes for composer.json
{
"require": {
"monolog/monolog": "1.0.*"
}
}
Note: You can create you composer.json with your required packages but i just created a simple composer.json file with monolog/monolog package. For your understanding you can follow my steps (this). You can remove the package monolog later on.
Now navigate to the project directory where composer.json file located
Run the following command:
composer require phpcasperjs/phpcasperjs
And you faced the above problem because of wrong or mismatched version of the intended package. Keep in mind that you always can create composer.json with your custom packages and their versions and which will be your package manager. For more detail about composer please visit Link
