  symfony/runtime contains a Composer plugin which is blocked by your allow-p  
  lugins config. You may add it to the list if you consider it safe.           
  You can run "composer config --no-plugins allow-plugins.symfony/runtime [tr  
  ue|false]" to enable it (true) or disable it explicitly and suppress this e  
  xception (false)
