補足

いくつが設定が足りなかったため、リソースを追加した。

execute "rbenv global #{node['ruby-env']['version']}" do
  command "/home/#{node['user']}/.rbenv/bin/rbenv global #{node['ruby-env']['version']}"
  user node['user']
  group node['group']
  environment 'HOME' => "/home/#{node['user']}"
end

cookbook_file "/home/#{node['user']}/.gemrc" do
  owner node['user']
  group node['group']
  mode '0644'
end

%w(rbenv-rehash bundler).each do |gem|
  execute "gem install #{gem}" do
    command "/home/#{node['user']}/.rbenv/shims/gem install #{gem}"
    user node['user']
