laravel 5 composer update omnipay fails - php

Question

I am having a problem with composer when I run composer update.
The relevant bits of my composer.json file looks like this:
"require": {
"php": ">=5.5.9",
"laravel/framework": "5.1.*",
"omnipay/common": "~2.0",
"omnipay/authorizenet": "~2.0",
"omnipay/firstdata": "~2.0",
"omnipay/stripe": "~2.0",
"omnipay/paypal": "~2.0"
},
"minimum-stability": "dev",
When I run composer update, I receive the following error:
[Composer\DependencyResolver\SolverProblemsException]
Problem 1
- The requested package omnipay/common could not be found in any version, there may be a typo in the package name.
Problem 2
- Installation request for omnipay/authorizenet ~2.0 -> satisfiable by omnipay/authorizenet[2.5.0].
- omnipay/authorizenet 2.5.0 requires omnipay/common ~2.2 -> no matching package found.
Problem 3
- Installation request for omnipay/firstdata ~2.0 -> satisfiable by omnipay/firstdata[v2.3.0].
- omnipay/firstdata v2.3.0 requires omnipay/common ~2.0 -> no matching package found.
Problem 4
- Installation request for omnipay/stripe ~2.0 -> satisfiable by omnipay/stripe[v2.4.3].
- omnipay/stripe v2.4.3 requires omnipay/common ~2.0 -> no matching package found.
Problem 5
- Installation request for omnipay/paypal ~2.0 -> satisfiable by omnipay/paypal[v2.6.3].
- omnipay/paypal v2.6.3 requires omnipay/common ~2.0 -> no matching package found.
Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details. Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.
I'm at a loss as to what direction to take to fix this or why it occurred in the first place. I last ran composer update several months ago and it ran with no issue.

Answer 1

There's no need to specifically require omnipay/common or omnipay/omnipay (which is a dummy package anyway).
(1) remove all of the omnipay/* lines from your composer.json
(2) The composer commands you need to bring your composer.json into having the correct versions are:
composer require omnipay/authorizenet
composer require omnipay/firstdata
composer require omnipay/stripe
composer require omnipay/paypal

Answer 2

Try running this command, I think composer will update your dependencies.
composer require omnipay/omnipay
I suppose the problem is with the package name. You can add omnipay/omnipay in your composer.json file as the package name.

Answer 3

I hope You Read All The Error Once. Its All Package You Declare is not found or not getting or its required update So, Just Remove the All The omipay packge form the Coposer.json and also Remove from ServiceProvider in config/app.php
Example Remove This Code Form Composer.json
"omnipay/common": "~2.0",
"omnipay/authorizenet": "~2.0",
"omnipay/firstdata": "~2.0",
"omnipay/stripe": "~2.0",
"omnipay/paypal": "~2.0"
And Then Try To Update Your Composer and Then After Install New Version Package From Here
I Hope Its Work For Your !!
