问题
Is it possible to reload all the packages installed using composer? I'm not sure if I made an accidental change to the source of on of the packages, and my app stopped working so I want to rule this out by reloading all the packages.
回答1:
You can generally just wipe the vendor/ directory and then run composer install to get everything back from your last known state (stored in composer.lock). Some plugins/custom installers in some frameworks however drop packages outside the vendor dir, but as far as I know with Laravel you should be ok doing this.
回答2:
I think php artisan dump-autoload should help.
