php - ZfcTwig is not loading config and fails in bootstrap -

hi relatively new zf2 might simple mistake making.

problem

when loading zfctwig module exception

fatal error: uncaught exception 'zend\servicemanager\exception\servicenotfoundexception' message 'zend\servicemanager\servicemanager::get unable fetch or create instance twig_environment' in /www/zendframework2/library/zend/servicemanager/servicemanager.php on line 555

this exception thrown in onbootstrap function of zfctwig\module.php:

<?php class module implements   bootstraplistenerinterface,   configproviderinterface {   public function onbootstrap(eventinterface $e)   {      /** @var \zend\mvc\mvcevent $e*/     $application    = $e->getapplication();     $servicemanager = $application->getservicemanager();     $environment    = $servicemanager->get('twig_environment'); // throws exception     //...   }   public function getconfig(){ return [/*...*/]; } // never called } 

what don't why bootstrap called before configuration loaded. 'twig_environment' service configured in config of zfctwig module, config has not been loaded, when onbootstrap called.

setup

zf2 loader via zf2_path environment variable. not using composer autoloader.

in application.config.php set additional modules path '/global/vendor' sytem wide repository of reusable modules. not using project local vendor folder.

from '/global/vendor/zfctwig' loading module zfctwig (link) twig template engine support in zf2.

since relies on twig library put twig lib '/global/vendor/twig'

to enable autoloading zfctwig module , twig library classes changed module.php of zfctwig implementing autoloaderproviderinterface , adding configs both twig , zfctwig.

<?php class module implements     bootstraplistenerinterface,     autoloaderproviderinterface,     configproviderinterface {     /**      * autoloading twig library , modules classes      * @return array      */     public function getautoloaderconfig()     {         $pathtotwiglib = dirname(dirname(dirname(__dir__))) . '/twig/twig/lib/twig';         return array(             'zend\loader\standardautoloader' => array(                 'namespaces' => array(                     __namespace__ => __dir__,                 ),                 'prefixes' => array(                     'twig_' => $pathtotwiglib,                 ),             ),         );     } 

in application.config.php loading modules ['application','twig','zfctwig']

auto loading twig working (at least can instantiate twig_environment in bootstrap of zfctwig , other controllers using new).

had config cache enabled

the problem wondering myself. config needs loaded before bootstrapping done. zf2 does, unless, me, have config cache enabled.

<?php // config/applicaiton.config.php return array(   'module_listener_options' => array(     // prevents call getconfig on modules     // implement configproviderinterface     // default: false     'config_cache_enabled' => true,    ) );
