Cannot install (problem with composer on PHP 7.2)

[kylelondonuk]

Hi, I tried running your suggested composer commands, but when I open vendor/autoload.php, I get this:

[25-Mar-2019 18:10:12 UTC] PHP Fatal error:  Uncaught Http\Discovery\Exception\DiscoveryFailedException: Could not find resource using any discovery strategy. Find more information at http://docs.php-http.org/en/latest/discovery.html#common-errors

I am running PHP 7.2. I looked at this link: http://docs.php-http.org/en/latest/discovery.html#common-errors and tried installing all the packages it mentions, but when I try the Puli install:

composer require puli/composer-plugin

i get this:

[InvalidArgumentException]                    
  Could not find package puli/composer-plugin.  
                                                
  Did you mean this?                            
      puli/composer-plugin

it looks like a full stop is somehow being added to the end of the word plugin?

Can you help?

Hum, it looks like php-http fails to find a suitable factory for http messages. And I'm pretty sure Puli is not the best option for you.
Did you run the command compose composer require php-http/curl-client guzzlehttp/psr7? What was the output? It should have install the factories from Guzzle.

Hi - thanks for such a quick response! Yes I ran that command and it all seemed fine. it suggested installing a few more at the end, but no errors... here it is:

And then I run this with my token, which is where the error comes:

$client = JoliCode\Slack\ClientFactory::create($yourToken);

[kylelondonuk]

And if it helps, here's the composer.json file:

"require": {
        "php-http/curl-client": "^2.0",
        "guzzlehttp/psr7": "^1.5",
        "jolicode/slack-php-api": "^1.1"
    }

[kylelondonuk]

Ah, i did

composer require zendframework/zend-diactoros

and that worked - was the problem just that guzzle wasn't installing the discovery factories for me?

[pyrech]

This behavior is quite strange because, as far as I know, zendframework/zend-diactoros & guzzlehttp/psr7 are equivalent libraries providing both PSR-7 implementations. They should work similarly. I do not really understand why guzzle's one is not detected correctly by the CommonClassesStrategy discovery 😕

I would say if Zend Diactoros works for you, just go ahead with it and remove guzzlehttp/psr7 😉

[vmunich]

I was having this when using guzzlehttp/psr7:

Http/Discovery/Exception/ClassInstantiationFailedException with message 'Unexpected exception when instantiating class.'

However, it works as expected when I install zendframework/zend-diactoros instead.

[damienalexandre]

Confirmed, the installation steps are broken. I'm going to take a deeper look at it.

[pawelkmpt]

It also fails for me. I tried to install puli/composer-plugin as suggested in http://docs.php-http.org/en/latest/discovery.html#puli-factory-is-not-available but failed as well.

composer require puli/composer-plugin
                                                                                                                                                                                     
  [InvalidArgumentException]                                                                                                                                                         
  Could not find a version of package puli/composer-plugin matching your minimum-stability (stable). Require it with an explicit version constraint allowing its desired stability. 

Defining version of that package also fails as one of its dependencies doesn't meet minimum stability condition. Basically chain reaction of errors.

[damienalexandre]

As a quick fix you can just force this package to version 1.x, the new 2.x version seams to be the problem:

"php-http/curl-client": "^1.0",

[damienalexandre]

Just updated the documentation. Please do not use curl-client 2.0, I have no idea why it does not found the client.

composer require php-http/curl-client:"^1.7" guzzlehttp/psr7

[pawelkmpt]

composer require php-http/curl-client:"^1.7" guzzlehttp/psr7

it works! thanks!

Closing as this issue is fixed now. Please feel free to submit a new issue if someone face again a similar error 🙂
