How to restore .json composer from an existing symfony2 project?

I need to work on a project on symphony 2 without composer configuration, but with the / * folder providers in the repository.

I want to reinstall the composer and create a configuration for an existing package. Is it possible?

Thanks!

You must create bare composer.json manually or using the composer init command.

And then you can list all the packages in the vendor folder on composer show --installed .

Then just generate the required section for composer.json with the specified values. And you're done. You can use regular expressions to make this easier.

I think you can do composer update , it will show you all the packages and then composer install ... one by one
