Error when upgrading to 5.2 - 'Class log does not exist'

Have you tried manually deleting the bootstrap/compiled.php file?

Edit;

Some people don't seem to understand how vars work and add spaces without adding double quotes for some reason.

Wrong

SOME_VAR=some value

Correct

MY_VAR="some value"

Have you tested a fresh install?

Looking at your error message, it has a lowercase L for log. Class log does not exist It may mean you have something which is referencing log instead of Log. Check all configs etc and compare to the master branch https://github.com/laravel/laravel

@bashy Thanks for recommending config files. The fix was in config/app.php replacing:

'rss_output_dir' => $app->environment('production') ? '/var/www/foo/public' : '/home/vagrant/homestead/foo/public',

with:

'rss_output_dir' => 'production' === env('APP_ENV') ? '/var/www/foo/public' : '/home/vagrant/homestead/foo/public',

(I'm using this because I found, like other people, that extending the configuration by adding a subdirectory with the environment name under /config/ didn't (or no longer) worked.)

I also had the problem. In the end I debugged it from the console by running php artisan and tracing the execution path step by step inside PHPStorm from the artisan.php-file in the project root. I did it simply by putting in the good old dd('here'); to see where the execution would stop.

I debugged it like this: In the file /vendor/laravel/framework/src/Illuminate/Foundation/Application.php I changed the method bootstrapWith to

    public function bootstrapWith(array $bootstrappers)
    {
        $this->hasBeenBootstrapped = true;

        foreach ($bootstrappers as $bootstrapper) {
            var_dump('bootstrapping: ' . $bootstrapper);
            $this['events']->fire('bootstrapping: '.$bootstrapper, [$this]);

            $this->make($bootstrapper)->bootstrap($this);

            var_dump('bootstrapped: ' . $bootstrapper);
            $this['events']->fire('bootstrapped: '.$bootstrapper, [$this]);
        }
    }

And ran php artisan again from the terminal. The last provider that started loading (but didn't finish) was LoadConfiguration provider. It gave me a clue where to look.

And so I changed the file /vendor/laravel/framework/src/Illuminate/Foundation/Bootstrap/LoadConfiguration.php in the method loadConfigurationFiles to:

    protected function loadConfigurationFiles(Application $app, RepositoryContract $repository)
    {
        foreach ($this->getConfigurationFiles($app) as $key => $path) {
            $repository->set($key, require $path);
            var_dump('loaded key: ' . $key . ' -- path: ' . $path);
        }
    }

After which it was clear that the last configuration key loaded was /config/queue.php string(87) "loaded key: queue -- path: /home/vagrant/Code/traeningsprojekt.dk/site/config/queue.php"

So it must be the file after that. And it was indeed - in my /config/services.php where I had the array key:

    // One key is for testing (doesn't send any actual mail), the other for real mails.
    'mandrill' => [
        'secret' => app()->environment() === 'testing' ? 'hidden-in-this-post' : 'also-hidden-in-this-post'
    ],

Phew what a journey. But in the end I solved it, and it was indeed a configuration issue.

OH! And DO remember to undo the two changes to the Illuminate files when you are done :-)

For me everything was so much easier but however stupid. :) I just forgot to write quotes around params in .env file ,that contains Space.

So it was like:

SITE_NAME = My SIte Name

But of course has to be

SITE_NAME = "My Site Name"

This was the error-causing stuff. :)

@ Garfild — observation works for me. In 5.1 works fine values without quotes but not anymore in 5.2

I have an fresh install and facing the same issue right now! any clue? I understand that there is a problem with log class, but what I do not get it is where this is happening exactly!

Hey Guys, I had a similar issue to this

I found that this was because i had a password for my email provider that had a space in it so i just put the password in 'xyz abc' and this resolved it for me... This was in the 'env' file which is referenced in the mail providers file

Apparently spaces are not welcome... its not nice when the errors are not so descriptive

@XenitXTD Use double quotes for that?

email_password="abc def"

testing an new installation and having the same issue... any clue?

I have tried everything I have could and nothing yet. Also, I went through all the config files and see if I had something different but still

Thanks!

Ok, the solution to this problem is right here >>> https://laracasts.com/discuss/channels/general-discussion/class-log-does-not-exist

It was because spaces in .env files vars!

This thread helped me out a great deal thanks everyone in here.

I did the same thing that @Garfild did and it work!

Hi,

Did you check that PDO PHP Extension installed? I had the same issue and it is fixed after installing PDO extension.

Was spaces in .env

Hi ,

can anyone help me out this error

@skovmand - Thanks for posting the details on how you debugged this. I followed the steps you provided and got what I needed within just a few minutes.

For me I ran into this issue running my site on the php-fpm docker container when hitting mb_internal_encoding('UTF-8'); in the LoadConfiguration class. Clearly the php-fpm container is missing something I need ^_^

Thanks for the hint to check for errors in the .env file. For me, it was a like with an empty value, just "foo=". That used to work in earlier versions of DotEnv, but apparently no longer does.

I'm not sure why the "log" error is the error that displays when there is a problem with the .env file, but something should be changed to make it display a more relevant error message.

here the way to go

Fell fowl of the same thing recently when updating some older projects; no quotes around .env variables with spaces.

Hi,

Just my 2 cents here. Go through your .env file and double-check that any string value with white-spaces is in quotes. e.g.:

MY_VAR=some value <-- bad

MY_VAR="some value" <-- good

it drove me crazy for 1 hours to realize about it. Just guessing, but it looks like the .env validation fails during the config load and (likely) a log line is written somewhere, BUT the Log facade is still not loaded which causes a crash.

Hii,

This error occurred because special character and space in .env file.

I hosted my application on shared hosting (BLUE HOST) suddenly i got error ; like this https://drive.google.com/open?id=0ByoLPyyQ3jAjZUFrRDk1ZGRLQVk

so i download my application run on my local host im getting this error

can any one give idea ???? why is that ???

Wow, thanks mr @bashy it works well :D

After many frustrating hours, the solution I found was to use env('APP_ENV') instead of App::environment(). In my config/services.php:

// credentials for loggly.com
'loggly' => [
    'key'   => '18f2blah_blah_blah',
    'tag'   => 'MyProject_'.env('APP_ENV'), // .strtolower(App::environment()) causes a reflection error about class log
],

Hi, Just just ran into the same error on a 5.2 project. I forgot to type the ::class static modifier after I updated the config/app.php with a new service provider.

e.g:

'providers' => [
 ...
MyVendor\MyServiceProvider
...
];

should be:

'providers' => [
 ...
MyVendor\MyServiceProvider::class
...
];
