Error message


I have a FAQ page with a link to view the page in .pdf.
However when I click on the link, I have the following error message:

Anyone knows what has to be done?

Thanks a lot.

Dear Isabelle,

This module has external dependencies (libraries) that need to be installed in order to generate PDFs. Unfortunately this is not possible in the current Drupal infrastructure.

It will be possible though in the new Drupal infrastructure in Openshift where we will migrate in a few months. There you will install the module using composer which will take are all the required dependencies and will install the module properly.

ok, thanks a lot for your answer!
