Symfony2 RuntimeException：将定义自动加载器的预期类“ Doctrine \\ DBAL \\ Driver \\ PDOMySql \\ Driver”

Question

I've deployed my site to my development server using Capifony and although it has been deployed correctly when I go the the site ie dev.xyz.co.uk/app_dev.php I get the following error:

RuntimeException: The autoloader expected class "Doctrine\\DBAL\\Driver\\PDOMySql\\Driver" to be defined in file "/var/www/vhosts/dev.xyz.co.uk/shared/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOMySql/Driver.php". The file was found but the class was not in it, the class name or namespace probably has a typo.

Any idea what's causing it? It works fine when deploying to production.

Answer 1

You may check the first line of the file "Driver.php" just to read <?php .

If you just read <? and tried to deploy on differents servers for dev and prod, just check if they have the same value for "short_open_tag" (in php.ini). If it's "on" on your prod's server and "off" on your dev's server you may have this error.

Answer 2

It can be problem of accelerator (xcache, eaccelerator, apc). Restart PHP it can help.
