[PHP5.4] Need help in setup pls

[Kazeshini94]

Trying to introduce cs-fixer into an old legacy project that still runs on php 5.4. I already introduced Composer (2.2.5) into the project and wanted to use CS-Fixer

composer require --dev friendsofphp/php-cs-fixer 

Which downloaded these files
  - Locking composer/semver (1.7.2)
  - Locking composer/xdebug-handler (1.4.6)
  - Locking doctrine/annotations (v1.2.7)
  - Locking doctrine/lexer (1.0.2)
  - Locking friendsofphp/php-cs-fixer (v2.2.20)
  - Locking ircmaxell/password-compat (v1.0.4)
  - Locking paragonie/random_compat (v2.0.21)
  - Locking psr/log (1.1.4)
  - Locking symfony/console (v2.8.52)
  - Locking symfony/debug (v2.8.52)
  - Locking symfony/event-dispatcher (v2.8.52)
  - Locking symfony/filesystem (v2.8.52)
  - Locking symfony/finder (v2.8.52)
  - Locking symfony/options-resolver (v2.8.52)
  - Locking symfony/polyfill-mbstring (v1.19.0)
  - Locking symfony/polyfill-php54 (v1.19.0)
  - Locking symfony/polyfill-php55 (v1.19.0)
  - Locking symfony/polyfill-php70 (v1.19.0)
  - Locking symfony/polyfill-php72 (v1.19.0)
  - Locking symfony/process (v2.8.52)
  - Locking symfony/stopwatch (v2.8.52)

and installed it ( I already got cs-fixer downloaded globally for my other Projects )
so i set the ExecutablePath over the full path name of me Application
now i wanted to start defining Rules and test them but i get this Error:

  [ErrorException]

Can`t find the $package['name'] in ToolInfo.php happens in the foreach() loop.

This is an untouched file from the vendor directory.

Error at ToolInfo.php:50

if (null === $this->composerInstallationDetails) {
    $composerInstalled = json_decode(file_get_contents($this->getComposerInstalledFile()), true);

    foreach ($composerInstalled as $package) {
         if (in_array($package['name'], array(self::COMPOSER_PACKAGE_NAME, self::COMPOSER_LEGACY_PACKAGE_NAME), true)) {
              $this->composerInstallationDetails = $package;

              break;
          }
     }
}

Found the Solution in Ticket #4905
Solution:

$packages = isset($composerInstalled['packages']) ? $composerInstalled['packages'] : $composerInstalled;

foreach ($packages as $package) { 

instead of

foreach ($composerInstalled as $package) {
