  • Welcome to Drupal Answers! In which directory did you execute Composer? Did you remove any Drupal file by mistake? Did you check none of the Drupal files is missing? – kiamlaluno Mar 12 '18 at 14:55
  • That said, you don't directly install a library on Drupal core, but you use a module that has the library as dependency. If there isn't any module that depends on that library, you create a custom module. – kiamlaluno Mar 12 '18 at 14:58
  • ok good i created i custom module and add class, but i don't know how i can pass variables to node.html.twig ? – Daniel Jean Mar 12 '18 at 17:48
  • Implement a preprocess function for nodes. – kiamlaluno Mar 12 '18 at 17:56
