php - Symfony 2- it looks like your system doesn't support relative symbolic links -

i'm new in symfony 2. started install symfony 2.7 on windows 7. downloaded composer , run in http://symfony.com/doc/current/book/installation.html

but when run command,

$ composer create-project symfony/framework-standard-edition my_project_name 

and set parametters database_host, database_name,.... default , hit enter error happened:

    trying install assets symbolic links. installing assets symfony\bundle\frameworkbundle web/bundles/framework looks system doesn't support relative symbolic links, assets  installed using absolute symbolic links. installing assets sensio\bundle\distributionbundle web/bundles/sensiodi stribution looks system doesn't support relative symbolic links, assets  installed using absolute symbolic links. 

my symfony still running there many errors. there many file missing in 'my_project_name\src\appbundle' folder folder in tutorial. , many error 'no route found "get /" 'when run '127.0.0.1:8000/app_dev.php/'; in browser can me fix php version 5.5.12

you need run composer administrator (of windows). create symbolic links.

also can change method default assets management after composer update or composer install changing in composer.json next line:

"symfony-assets-install": "relative", 

to this:

"symfony-assets-install": "symlink", 

or this:

"symfony-assets-install": "hard-copy",
