Directory Permissions
After installing Laravel, you may need to configure some permissions. Directories within the
storageand thebootstrap/cachedirectories should be writable by your web server or Laravel will not run.
https://laravel.com/docs/5.4/installation#installing-laravel
So, for example, in Linux you can do this by executing chmod command:
chmod -R 755 storage bootstrap/cache
This is not a complete answer. I set the permissions and am still getting permission denied on laravel.log.
@JayBienvenu instead of downvoting you could try to find a problem in your system and add your own answer. This solution perfectly works for me for years (Linux, Mac OS).
That's what I've spent most of this afternoon doing. Thanks for your help.
The resolution was to set it to 777 instead of 755.
