Git crashes while installing libraries

I'm starting using Doctrine (2.0.0 Beta5). I've tried to install doctrine-fixtures and DoctrineFixturesBundle by adding

[doctrine-fixtures]     
    git=https://github.com/doctrine/data-fixtures.git
    target=/

[DoctrineFixturesBundle] 
    git=https://github.com/symfony/DoctrineFixturesBundle.git
    target=/bundles/Symfony/Bundle

to my deps file. Then I've launched a command like this

php bin/vendors install

Here's an error

> Installing/Updating doctrine-fixtures
fatal: Not a git repository (or any parent up to mount parent )
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
> Installing/Updating DoctrineFixturesBundle
fatal: Not a git repository (or any parent up to mount parent )
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).

And here's the whole output

Try this. I think, that you didn't write git address right.
