How to install 3rd party library to Symfony 3.1 via composer?

Question

I'm trying to develop a web application using Symfony 3.1 and I need to use some external library like Faker and Guzzle. However, everytime I try to install them with composer like this:

composer require fzaninotto/Faker

It always throws an errors like this:

Using version ^1.6 for fzaninotto/Faker
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
  - Installing fzaninotto/faker (v1.6.0)

Do I really need to use a 3rd party symfony bundle for this or how can I use the library "as is"?

It seems you have put a "service" block inside your config_dev.yml and it means, there is no bundle installed and associated with that configuration.

Just remove that "service" block and you should be fine, because clean installation of symfony and running

composer require fzaninotto/Faker

works like a charm.

Simply typo in your config.yml file, you wrote service: instead of services:.

You can autoload a third party library with composer like this

// composer.json
{
    // ...

    "autoload": {
        "psr-4": {
            "Custom\\Namespace\\": "relative/path/to/library"
        }
    }
}

The path must be relative to package root.

You can find more informations in the composer documentation.
