Laravel 8 Conflict

[marbuser]

Laravel 8 Upgraded to Guzzle 7. Omnipay uses php-http/guzzle6-adapter which has a constraint set for only Guzzle 6.

You can specify a different adapter by using omnipay/common instead of league/omnipay:

composer require omnipay/common:^3 php-http/curl-client

I think Guzzle 7 supports the php-http implementation directly, so can you try with just omnipay/common instead of league/omnipay?
I'll test with requiring Guzzle 7 by default now: #615

@barryvdh Nope, I changed it and same issue.

"omnipay/common": "^3.0",
"omnipay/paypal": "^3.0",

@marbuser you can check that in September 2020, a few days after this post got written, Composer got an update with Guzzle 7: 1ba7c8a

Hi..!
I'm also trying to run composer require league/omnipay:^3 omnipay/paypal in my Laravel 8 project but having following issue:
Problem 1
- php-http/guzzle6-adapter[v1.1.0, ..., v1.1.1] require guzzlehttp/guzzle ^6.0 -> found guzzlehttp/guzzle[6.0.0, ..., 6.5.x-dev] but it conflicts with your root composer.json require (^7.0.1).
- league/omnipay v3.0.0 requires php-http/guzzle6-adapter ^1.1 -> satisfiable by php-http/guzzle6-adapter[v1.1.0, v1.1.1].
- Root composer.json requires league/omnipay 3 -> satisfiable by league/omnipay[v3.0.0].
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require omnipay/paypal:*" to figure out if any version is installable, or "composer require omnipay/paypal:^2.1" if you know
which you need.

After that when I try running composer require league/omnipay:^3 omnipay/paypal -W it gives me following error:
Problem 1
- php-http/guzzle6-adapter[v1.1.0, ..., v1.1.1] require guzzlehttp/guzzle ^6.0 -> found guzzlehttp/guzzle[6.0.0, ..., 6.5.x-dev] but it conflicts with your root composer.json require (^7.0.1).
- league/omnipay v3.0.0 requires php-http/guzzle6-adapter ^1.1 -> satisfiable by php-http/guzzle6-adapter[v1.1.0, v1.1.1].
- Root composer.json requires league/omnipay 3 -> satisfiable by league/omnipay[v3.0.0].

My composer file:
"require": {
"php": "^7.3|^8.0",
"fruitcake/laravel-cors": "^2.0",
"guzzlehttp/guzzle": "^7.0.1",
"laravel/framework": "^8.75",
"laravel/sanctum": "^2.11",
"laravel/tinker": "^2.5"
},

Anybody, please help me with this issue!

Further more, I tried running:
composer require league/common:^3 which gives error stated: Could not find package league/common.
And composer require omnipay/common:^3 which gives the following:
Problem 1
- Root composer.json requires omnipay/common 3 -> satisfiable by omnipay/common[v3.0.0].
- omnipay/common v3.0.0 requires php-http/client-implementation ^1 -> could not be found in any version, but the following packages provide it:
- symfony/http-client Provides powerful methods to fetch HTTP resources synchronously or asynchronously
- php-http/guzzle6-adapter Guzzle 6 HTTP Adapter
- symfony/symfony The Symfony PHP framework
- php-http/curl-client PSR-18 and HTTPlug Async client with cURL
- php-http/guzzle7-adapter Guzzle 7 HTTP Adapter
- kriswallsmith/buzz Lightweight HTTP client
- php-http/mock-client Mock HTTP client
- php-http/socket-client Socket client for PHP-HTTP
- php-http/guzzle5-adapter Guzzle 5 HTTP Adapter
- voku/httpful A Readable, Chainable, REST friendly, PHP HTTP Client
- php-http/react-adapter React HTTP Adapter
- christophwurst/nextcloud-http-client HTTPlug and PSR7 adapter for Nextcloud
- jorge-matricali/http-client A wrapper of libcurl that implements PSR-7 HTTP message interface.
- code-tool/curl-client cURL client
- juststeveking/http-slim A slim psr compliant http client to provide better interoperability.
- php-http/buzz-adapter Buzz HTTP Adapter
- code-tool/socket-client Socket client for PHP-HTTP
- php-http/cakephp-adapter Cake adapter for PHP-HTTP
- windwalker/framework The next generation PHP framework.
- windwalker/http Windwalker Http package
... and 36 more.
Consider requiring one of these to satisfy the php-http/client-implementation requirement.

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.
• It's a private package and you forgot to add a custom repository to find it
