I downloaded the latest stable release of Drush this morning, and ran it, only to have it error out and not do anything, which is a first with Drush for me.
The error is ”Fatal error, class Console_Table not found in file⦔.
Using the link below:
http://svn.php.net/viewvc/pear/packages/Console_Table/trunk/Table.php?revision=267580&view;=co
Copy that code and save the file as table.inc. Place the file in /drush/includes/ and drush should then be working for you.
I’m not sure why this suddenly started happening, someone noted it could be from the move from CVS to SVN over at php.net.
