user47544: I am using code from GitHub.
Once I run composer its gives error as:

C:\wamp64\www\bitcoin-php-master>composer require bitwasp/bitcoin
  Using version v0.0.33.1 for bitwasp/bitcoin
  ./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 bitwasp/bitcoin No version set (parsed as 1.0.0) is
satisfiable by bitwasp/bitcoin[No version set (parsed as 1.0.0)] but these confl
ict with your requirements or minimum-stability.

Installation failed, reverting ./composer.json to its original content.



user1652: Since Bit-Wasp/bitcoin-php has its own composer.json file, after cloning you should just run:
composer install

If there is still some issue, run the following command to diagnose the problem:
composer self-update
composer diagnose

Otherwise report it at the project page.
