Troubleshooting

Here is common list of troubleshooting if you encountering errors.

Console application won't start

For example if you can't load node socket service using

app/console nodesocket start

and returns error such as:

[Symfony\Component\Debug\Exception\ContextErrorException] Warning: file_put_contents(myproject/app/cache/runtime_node/): failed to open stream: Is a directory

than you need to setup properly configuration or is not activate in app/console.yml configuration. This example of configuration is on Step 4 documentation.

Configuration loader returns no extension

Starting a service produces an error:

$event = $this->get('service_nodesocket');

When you calling a service and you receive error such as no extension or error in dependecy Injection. This example produce error:

[Symfony\Component\DependencyInjection\Exception\InvalidArgumentException] There is no extension able to load the configuration for "reactorcoder_symfony2_nodesocket" (in /data/development/web/www/symfony2/myproject/app/config/config_dev.yml). Looked for namespace "reactorcoder_symfony2_nodesocket", found "framework", ...

This errors are because in a framework of kernel are not loaded instance in AppKernel.php descripted in Step 2 documentation.
