Laravel and Mysql 'has gone away'

Question

I'm trying to set up a new project on MacOS (and it is a first time for me). After a while I managed to have a MySQL instance that seemed correct (as I could connect both from a client and the command line).

However, if I try to run anything from my Laravel project, I get the 'MySQL server has gone away' exception. This started when I tried to run the (very small) migrations from my project, but is not related to the size of them. I dug deeper, and tried to use Tinker and a basic

DB::connection()->getPdo();
command. This works fine on my Windows environment, as well as Linux. Not on Mac OS. I even tried connecting with a wrong password, and I got the same exception (as opposed as the 'Wrong Password' expected exception).

So there is definitely something fishy going on in my configuration, however I'm not sure how to investigate further. Any help would be appreciated. Thanks!

尝试在mysql配置中增加max_allowed_packet 。
