I've got drupal 7 and drush on Mac OSX 10.7 The original PHP install (as shipped) is 5.3.25. with that configuration I was able to upgrade drupal sites running locally for several occassions. One site used sqlite, the other mysql. Now I have installed PHP 5.4.15, as well as the mysql and sqlite drivers for php54. Now when I run drush updb, I get the following: A PDO database driver is required! You need to enable the PDO_SQLITE (or PDO_MYSQL) database driver for PHP 5.2.4 or higher so that Drupal 7 can access the database. I find Applications/MySQLWorkbench.app/Contents/Resources/libraries/pysqlite2/_sqlite.so /opt/local/lib/php54/extensions/no-debug-non-zts-20100525/pdo_sqlite.so and opt/local/lib/php54/extensions/no-debug-non-zts-20100525/mysql.so /opt/local/lib/php54/extensions/no-debug-non-zts-20100525/pdo_mysql.so Worse, if I set the php execute as php54, drush freezes on the drush updb command. No error messages, just stalls. This is a mess. I feel that I am back in linux 6 dependency hell! BTW: Those of you who might be using homebrew and would recommend that I convert, would be on the right track but unfortunately I have over 200 _active_ packages installed via macports. Where do I start? thanks -- Tim tim at tee jay forty nine dot com or akwebsoft dot com http://www.akwebsoft.com
