"No PSR-17 request factory found" incorrectly suggests guzzlehttp/psr7

PHP version: 7.3

Description
Hi!

This seems related to #156 and #149.

I received the error:

No PSR-17 request factory found. Install a package from this list: https://packagist.org/providers/psr/http-factory-implementation

But when I go to https://packagist.org/providers/psr/http-factory-implementation, the first item on the list is guzzlehttp/psr7. When I installed it, I got the same error. After some deep digging, If found out that I actually needed http-interop/http-factory-guzzle. Installing that package does fix things - it's just the recommendation that was wrong (and tough to debug!).

Am I correct that guzzlehttp/psr7 should not be shown on the list of "http factory implementations"? If so, why is it there? Is it a bug in that package's metadata? Something on Packagist? I don't know much about this - I'm just trying to get a bundle that is a few layers above this to work :).

Thanks!

No you aren't: the guzzlehttp/psr7 package is providing all PSR-17 factories but only starting from version 2.0.x-dev which is currently in development (the change is already in master), thus Packagist is correctly showing this package as a provider for the psr/http-factory-implementation virtual package. The error you got is due to the reason explained above: the version you have installed is not supporting PSR-17 and anyway the php-http/discovery package is not able to discover the newest version. I opened a PR to fix this, but if you want to stop requiring the http-interop/http-factory-guzzle package you will also have to update to an unstable version of the guzzlehttp/psr7 package

A year later the package is still not taged :/

This took me an hour to figure hour, painful WTF. The dev version packages should not be part of list that provide interface.

i am not exactly sure what you are reporting. afaik the only thing not tagged in php-http/discovery is the removal of puli. which should have been tagged, i am doing that now.

I'm sorry, this might not be related to your repository.
