Answer 1

I believe this error results from not being able to find mcrypt.

Script php artisan optimize handling the post-update-cmd event returned with an error

Apparently it is not quite that easy to install mcrypt.

1. Install the php5-mcrypt package, or verify that it has been installed correctly.

   sudo apt-get install php5-mcrypt
   

2. Check whether mcrypt has been installed and enabled for PHP:

   php --ri mcrypt
   

3. You're done if it says:

   mcrypt support => enabled
   

   Otherwise, continue if it says:

   Extension 'mcrypt' not present.
   

4. Verify that mcrypt.ini is present in PHP's mods-available directory.

   ls /etc/php5/mods-available/mcrypt.ini
   

5. If it says No such file or directory, create a symbolic link from mcrypt.ini to PHP's mods-available directory.

   sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available
   

6. Enable the mod.

   sudo php5enmod mcrypt
   

7. Restart apache.

   sudo service apache2 restart
   

8. Check again whether mcrypt is enabled.

   php --ri mcrypt
