php - Use of undefined constant MCRYPT_RIJNDAEL_128 - assumed 'MCRYPT_RIJNDAEL_128'

Question

I have successfully installed Laravel, but after running php artisan serve and going to localhost:8000 I get this error:

Use of undefined constant MCRYPT_RIJNDAEL_128 - assumed 'MCRYPT_RIJNDAEL_128'

I have checked phpinfo() on localhost:8888 and it says that mcrypt is properly installed. However the only thing I can think of is that maybe my path is wrong?

in my .bash_profile I have

PATH=/usr/local/bin:$PATH

Every time I try to run Laravel commands I have to type this in the terminal:

export PATH="~/.composer/vendor/bin:$PATH" 

I am running on a Mac. Is there a simple way I can set up my bash_profile so that I can consistently change between localhost addresses and still have all the proper PHP functions working?

Answer 1

More simple way on ubuntu

• apt-get install php5-mcrypt
• mv -i /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/
• php5enmod mcrypt
• service apache2 restart

Note: if you don't have "/etc/php5/conf.d" just skip that step and it will work ok
