Chef – 通知多個包

我正在嘗試在 CentOS 7 上部署 postgresql 9.4

package ['postgresql94-server', 'postgresql94-contrib'] do
   action :nothing
end

execute "yum check-update" do
   command "yum check-update"
   action :nothing
end

package 'Install Postgres Repo' do
   package_name 'pgdg-redhat94'
   source '/tmp/pgdg-redhat94-9.4-2.noarch.rpm'
   notifies :run, 'execute[yum check-update]', :immediately
   notifies :install, 'package[postgresql94-server, postgresql94-contrib]', :immediately
   action :nothing
end

execute 'Download Postgres repo RPM' do
   command 'curl http://yum.postgresql.org/9.4/redhat/rhel-7-x86_64/pgdg-redhat94-9.4-2.noarch.rpm -o /tmp/pgdg-redhat94-9.4-2.noarch.rpm'
   notifies :install, 'package[Install Postgres Repo]', :immediately
end

我收到以下錯誤：

我究竟做錯了什麼？

雖然該錯誤報告中正在解決此問題，但這裡有一個解決方法：

p = package ['postgresql94-server', 'postgresql94-contrib'] do
   action :nothing
end
# ...
notifies :install, p, :immediately

您始終可以為通知傳遞顯式資源對象。
