I'm a beginner in PHP and other stuff and I have problem with Sylius (for symfony2) installation. I used XAMP and windows 7. After the command
$ php app/console sylius:install
in step 2 of 4 i got fatal error:
Uncaught exception 'Symfony\Component\Filesystem\Exception\IOException' with message "Cannot rename "C:\Users\xyz\sylius\app\cache\de_" to "C:\Users\xyz\sylius\app\cache\dev".
in C:\Users\xyz\sylius\sylius\vendor\symfony\symfony\src\Symfony\Component\Filesystem\Filesystemphp:262.
I have no idea what to do next. I tried cache:clear and normal delete cache folder but it's still doesn't work. Any ideas? I'm a beginner so if you could explain it I would be grateful. PHP is really hard for me... :(
