How to get list of all installed packages along with version in composer?

I have been working on a project using Symfony 2.1 on my local machine. I have uploaded it to my server but when I try and install the vendor bundles using Composer, I’m getting a lot of dependency errors. Presumably this is something to do with the latest version of Symfony just being released and my composer.json file not specifying exact version numbers.

Is there any way I can quickly display the version numbers of everything on my local machine?

Here is my composer.json file (which worked fine until a few days ago):
