Uncaught ReflectionException: Class log does not exist in /vendor/laravel/framework/src/Illuminate/Container/Container.php:738

Question

I had my Laravel 5.2 working well, I was happy.

Then I executed :

 php artisan config:cache

And my day became darker

I got this message:

PHP Fatal error:  Uncaught ReflectionException: Class log does not exist in /home/vagrant/Code/vendor/laravel/framework/src/Illuminate/Container/Container.php:738

I don't really know how to debug it,

I tried to remove anything that I lastely did. Some says it is a .env file with spaces inside, but not in my case, so basically, I don't know how to debug it.

I tried

composer dump-autoload

I tried to delete vendor folder

All php artisan commands fails.

It seems to happen to a lot of people but the cause always different and difficult to debug.

Any help will be appreciated!

EDIT 1: I could restore a functional version of my site deleting

bootstrap/cache/config.php

I also did a php artisan config:cache before it fails

and restoring a previous version of

    bootstrap/cache/services.php

But I would like to use those commands, because they make a significant difference in production!

Answer 1

As noodles_ftw says, this was a config file issue. so, checking for errors in my config folder did the trick, I had an error in jwt.php

Hope it helps!
