L'installazione di più pacchetti tramite Vagrant + Chef

Question

Ho appena scoperto Vagrant + Chef e sto cercando di creare una ricetta semplice da installare più pacchetti sul nodo. Ho pensato che qualcosa di simile potrebbe funzionare (io sono del tutto nuovo tu ruby):

# (From cookbooks/MY_COOCKBOOK/recipes/default.rb)
# Install required packages
%w{build-essential libncurses5-dev openssl libssl-dev}.each do |pkg|
  package pkg do
    action :install
  end
end

Ma questo non riesce con il seguente errore:

Ho l'impressione che mi manca qualcosa di base qui ...

Answer 1

Si è scoperto che stavo semplicemente mancava la ricetta "apt" sul mio Vagrantfile, che corrono un apt-get update prima di installare i pacchetti necessari. Quindi, quanto sopra è stato corretto.

Answer 2

Just adding this answer here for future reference. If you ever run into a situation where you must run apt-get update before calling some package commands, you can resort to this snippet:

execute "update package index" do
  command "apt-get update"
  ignore_failure true
  action :nothing
end.run_action(:run)

And it works fine.
