'Lcobucci\JWT\Signer\Key\InMemory' not found

yacineblr commented 3 years ago

Hi, I just installed the lib with composer and I have a problem with the lib "Lcobucci/JWT".

Error:

Fatal error: Uncaught Error: Class 'Lcobucci\JWT\Signer\Key\InMemory' not found in /wp-content/plugins/myplugin/Firebase/vendor/kreait/firebase-tokens/src/Firebase/Auth/Token/Generator.php on line 38

My composer

    "minimum-stability": "dev",
    "require": {
        "kreait/firebase-php": "^5.19",
        "kreait/firebase-tokens": "^1.15"
    }

My php file

  use Kreait\Firebase\Factory;
  use  Kreait\Firebase\Auth;

  $factory = (new Factory)->withServiceAccount(__DIR__ . '/google-service.json);

  $auth = $factory->createAuth();

Do you know what the error is, please ?

The error indicates that a required class cannot be found (Lcobucci\JWT\Signer\Key\InMemory). This could have many reasons:

The autoloader of your project didn't pick up the class, you can try to composer dumpautoload and see if that helps.
If you're planning on using the SDK and not just the tokens library, you can remove the kreait/firebase-tokens dependency, as it is included in kreait/firebase-php
It could be that other dependencies in your project prevent a working installation of the SDK

You can check what is installed by running composer show and see which version of the kreait and lcobucci/jwt libraries are installed. lcobucci/jwt should be a version greater than 3.4.1, kreait/firebase-php should currently be greater than 5.20.1 and kreait/firebase-tokens should be ^1.15.

I don't know how composer behaves in the context of a Wordpress project / Wordpress plugin (I've seen it in a file path of your original post), so I'm afraid I can't help with that.

Composer log after "composer installl":

  Problem 1
    - kreait/firebase-php[5.20.1, ..., 5.x-dev] require php ^7.4|^8.0 -> your php version (7.3.11) does not satisfy that requirement.
    - Root composer.json requires kreait/firebase-php ^5.20.1 -> satisfiable by kreait/firebase-php[5.20.1, 5.x-dev].

It was a problem with my PHP version (7.3.11) of "compose". It was installing "kreait/firebase-php" in version 5.19 and not the latest "5.20.1".

Thanks to the fact that you told me the version number, I solved the problem
