One time login url: &lt;http://127.0.0.1:8888/user/reset/1/1560664888/oDldybNCOH_0nRc1n4YXZWm2NwEehXnN63rWHq_Isqo/login&gt;
Press Ctrl-C to quit the Drupal development server.

Server command: '/Applications/MAMP/bin/php/php7.2.1/bin/php' '-S' '127.0.0.1:8888' '.ht.router.php'


Unfortunately the given URL returns with HTTP error code 500. Also I added -vvv and --verbose no additional error messages are visible.

When I change from MAMP to OS X standard PHP installation the browser shows:

Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0

Fatal error: Unknown: Failed opening required '.ht.router.php' (include_path='.:') in Unknown on line 0


Actually there's no .ht.router.php from where I started the quick-start command.
