composer error on installing

You're adding $ to the installation command, which is not necessary. It is included in the README to indicate a console command.

Can you show the contents of your composer.json file? Aside from the misuse of $ the first time you run the commands, when you do run the command correctly, you're getting an error about Composer being unable to satisfy requirements. This could be due to any number of issues, and seeing the contents of your composer.json will help us troubleshoot.

Thanks!

Thank you all of you for giving me your time, this is my composer.json file contents...!!

{ "name": "league/oauth2-github", "description": "Github OAuth 2.0 Client Provider for The PHP League OAuth2-Client", "license": "MIT", "authors": [ { "name": "Steven Maguire", "email": "stevenmaguire@gmail.com", "homepage": "https://github.com/stevenmaguire" } ], "keywords": [ "oauth", "oauth2", "client", "authorization", "authorisation", "github" ], "require": { "php": ">=5.5.0", "league/oauth2-client": "~1.0" }, "require-dev": { "phpunit/phpunit": "~4.0", "mockery/mockery": "~0.9", "squizlabs/php_codesniffer": "~2.0" }, "autoload": { "psr-4": { "League\OAuth2\Client\": "src/" } }, "autoload-dev": { "psr-4": { "League\OAuth2\Client\Test\": "test/src/" } }, "extra": { "branch-alias": { "dev-master": "1.0.x-dev" } } }

This is the composer.json file for the league/oauth2-github package. Do you have a composer.json file for your own project?

no, i want to install this package but its give me error, i already installed oauth2-google package its successfully installed but this one give me error.

I recommend reading this guide to Composer first. Let me know if you still have installation issues afterwards.
