Error creating Symfony2 project from composer

Question

I try to create a Symfony2 project with composer on Ubuntu with command:

php composer.phar create-project symfony/framework-standard-edition projectpath

And I get this error

Installing symfony/framework-standard-edition (dev-master 506ffaab8d8474db2512fca879ca4b9877616a1e)
  - Installing symfony/framework-standard-edition (dev-master master)
    Cloning master

Created project in projectpath/
Loading composer repositories with package information
Installing dependencies from lock file

  Problem 1
    - Installation request for symfony/symfony == 2.1.9999999.9999999-dev -> satisfiable by symfony/symfony 2.1.x-dev.
    - Can only install one of: symfony/symfony dev-master, symfony/symfony 2.1.x-dev.
    - Installation request for symfony/symfony == 9999999-dev -> satisfiable by symfony/symfony dev-master.

composer.phar update also return an error.

Any ideas?

Try by specifying the exact version you want, it has now been fixed in the symfony-standard repo and this should work:

 php composer.phar create-project symfony/framework-standard-edition projectpath 2.1.x-dev
