Cant update with composer

[MichaelHindley]

Running "composer.phar update" on symfony 2.1 RC1 results in:

Updating dependencies

• Updating twig/twig (dev-master)

  [RuntimeException]
  Failed to execute cd "D:\wamp\www\Symfony\vendor/twig/twig" && git status -
  -porcelain --untracked-files=no

  fatal: Not a git repository (or any of the parent directories): .git

This error is brand new with 2.1 RC1.

What's the relationship with this bundle ?

[MichaelHindley]

The relationship is that JMS tries to update its twig dependency even though twig is fully updated and fails to update and thus fails to install on a fresh 2.1 RC install, I have not encountered this problem with any other bundle so I figured to post it here rather than in twig repo.

I cannot help you here. Please post this on composer with the exact steps to reproduce. Please also check whether this happens on a fresh install (e.g. delete your entire vendor folder).

Thanks!
