Issue with installing Postgres on Vagrant VM using Chef: undefined method `ruby' for Config:Module

问题

That's how my Vagrantfile looks :

   config.vm.provision :chef_solo do |chef|
     chef.cookbooks_path = "cookbooks"

     chef.json = {
        postgresql: {
            password: {
                postgres: 'password'
            }
        },
        database: {
            create: ['mydb']
        },
        'build-essential' => {
            compiletime: true
        }

     }
     chef.run_list = ['recipe[build-essential]', 'recipe[openssl]', 'recipe[postgresql::server]', 'recipe[database::postgresql]']

   end

Also I used precise32 box. And while my VM starts after vagrant up, I get very long traceback with error message: undefined methodruby' for Config:Module`.

Does anybody encountered this?

There appears to be a problem installing the "pg" gem:

I suggest reading the documentation of the build-essentials cookbook. It suggests setting the "compiletime" attribute in order to support to ensure that the build tools are available to compile RubyGems extensions.

Update 1

The following json settings worked for me:

chef.json = { 
  "postgresql" => {
    "password" => {
      "postgres" => "password"
    }
  },
  "database" => {
    "create" => ["encased_dev"]
  },
  "build_essential" => {
    "compiletime" => true
  }
}

Note:

Attribute is "build_essential" and not "build-essential"

Updated 2

I have since discovered that there is a ruby recipe that fixes this issue as well (by setting the build essential node attributes about). Either add it to your run-list or use the database cookbook
