Chef crashes when installing gem

Im using chef and vagrant as provisioner.

When I try to install gems as follows, the app crashes:

metadata.rb

gem 'faraday'
gem 'json'

default.rb

require 'faraday'
require 'json'

conn = Faraday.new(:url => 'http://127.0.0.1:8200')

This error raises:

Chef never successfully completed! Any errors should be visible in the
output above. Please fix your recipes so that they properly complete.

It seems that gcc is missing, but I can't install it because it tries first to install gems and then executes the recipe, so it crashes before I can do anything.

-- EDIT --

I've added these lines and is working:

metadata.rb: (Remove gem dependency from here)

depends 'hashicorp-vault', '~> 2.5.0'
depends 'build-essential', '~> 8.0.3'

default.rb:

include_recipe 'hashicorp-vault::default'
chef_gem 'faraday'
chef_gem 'json'
require 'faraday'
require 'json'

The Chef-y way to install gcc is to use the build-essential cookbook.

Recipes are perfectly capable of running arbitrary commands, so if you know how to do it manually you can do it with Chef in a pinch. That being said you should guard any arbitrary commands so they aren't run every single time the recipe runs, only when they're needed.

execute 'sudo yum groupinstall \'Development Tools\'' unless <your logic for 
detecting gcc goes here>

Chef also has Ohai which gathers metadata about the run before it even starts, including what OS you're operating on, so you can make your recipe multiplatform by leveraging that.

https://docs.chef.io/dsl_recipe.html

include_recipe 'mycookbook::debian' if node['platform_family'] == 'debian'
include_recipe 'mycookbook::rhel' if node['platform_family'] == 'rhel'

Or, to give you more flexibility if you plan on having many platform types

possible_platforms = ['debian', 'rhel']
if possible_platforms.contains? node['platform_family']
   include_recipe "mycookbook::node['platform_family']"
else
    puts 'This platform isn't valid'
end

Add a shell provisioner before the chef provisioning?

In your Vagrantfile for example:

Vagrant.configure("2") do |config|
    config.vm.provision :shell, inline: 'yum install -y gcc'
    config.vm.provision :chef, inline: '...'
end
