Ok, you want to install a bundly in Symfony2, and you are going to use git. You go to your root directory... but, here is the problem

Command:

{syntaxhighlighter brush: as3;fontsize: 100; first-line: 1; }git submodule add git://github.com/simplepie/simplepie.git vendor/simplepie{/syntaxhighlighter}

Yes, it's Simplepie bundles for Symfony2. Ok, the error:

 

{syntaxhighlighter brush: as3;fontsize: 100; first-line: 1; }fatal: Not a git repository (or any of the parent directories): .git{/syntaxhighlighter}

It's quite simple. You don't have initialized git:

{syntaxhighlighter brush: as3;fontsize: 100; first-line: 1; }$git init > Initialized empty Git repository in /var/www/symlabs/[project]/.git/ {/syntaxhighlighter}

Try again and... Yes, you welcome :-)
