bin/console missing after running composer install

Symfony 2 => app/console

Symfony 3 => bin/console

I had deleted the bin directory assuming that the executable console file would be created in my next composer install. I was wrong! Don't gitignore your bin/composer file and also make sure that if you are using the symfony 3 folder structure, you don't have .gitignore for the symfony 2 folder structure.

I had the same problem because I was accostumed to add the bin directory to my .gitignore file, because in Symfony2 all bin files (including the ones from other vendors) where placed in that folder, but that is not the case in Symfony3, so we can add the bin directory to our code repositories.

You can solve problem installing a new application (using the symfony installer) and copying the bin directory from this new project to your own project.
