wordpress can't create debug.log

I need to create debug.log, but for some reason it was not created.

Things I've tried:

1. Installing plugin that should allow logging, to create history of my problems.
2. editing wp-config.php with debug lines:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_DISPLAY', true );
define( 'WP_DEBUG_LOG', '/tmp/wp-errors.log' );

I hope it ends well :D
