When trying to run Drush on my shared hosting account I get this error:
Your command line PHP installation is too old. Drush requires at least PHP 5.3.0.
To suppress this check, set the environment variable DRUSH_NO_MIN_PHP=1
When I type
php --version, it tells me that I am running PHP 5.2.6.
The .bashrc file has the following lines
export COLUMNS alias drush='/usr/bin/php ~/public_html/drush/drush.php' alias php='/usr/bin/php'
How I can fix this?
