configurations

Just follow this document

You might need to restart PHP so you can do this using the following command (command will change according the PHP version you have).

brew services restart php@7.1

Generally if you are not sure where your JAVA_HOME is the first thing you would do is type in the following command

echo $JAVA_HOME

But more times than usual if you have not intentionally set this variable in your MAC you would see an empty response. So now how would you proceed to find the real JAVA_HOME.  Some times a quick solution is looking in /System/Library/Frameworks/JavaVM.framework/Versions. Still there can be a lot of Java HOME's in there (like what happened to me).

1. First copy sites/example.settings.local.php to default/settings.local.php
2. Now uncomment the following lines in default/settings.php

   # if (file_exists(__DIR__ . '/settings.local.php')) {
   #   include __DIR__ . '/settings.local.php';
   # }

3. Now debugging is set. You also can use the following command

   drupal routing:debug <route name>

   This command will give the user information regarding a specific route
