I get an error when trying to use artisan command tinker. For example I would like to add a user. In my terminal I type

$ php artisan tinker 

Answer 1

One or more of readline posix and pcntl extensions are missing. You need to compile PHP with the appropiate configuration options to enabled it.

Here are the instructions:

• readline http://www.php.net/manual/en/readline.installation.php
• pcntl http://www.php.net/manual/en/pcntl.installation.php
• posix http://www.php.net/manual/en/posix.installation.php

Note that posix functions are enabled by default.
