Attempted to load class "Compiler" from namespace "Leafo\ScssPhp".

[abelardolg]

Hi there,

I am using the package:
"scssphp/scssphp": "^1.0.6"

When I delete vendor, var/cache and clear cache of composer, I run:
composer install

then this message outputs:

Attempted to load class "Compiler" from namespace "Leafo\ScssPhp".           
  Did you forget a "use" statement for e.g. "Twig_Compiler", "Twig\Compiler",  
   "Symfony\Component\ExpressionLanguage\Compiler", "Symfony\Component\Depend  
  encyInjection\Compiler\Compiler" or "ScssPhp\ScssPhp\Compiler"? 

Then, I run the following command:

fgrep -R "use Leafo" vendor/

and I discovered that your package still uses Leafo/scss (this package was abandoned in favour of scssphp/scssphp):

vendor/kriswallsmith/assetic/src/Assetic/Filter/ScssphpFilter.php:use Leafo\ScssPhp\Compiler;

Operating System: Ubuntu 18.04.3 LTS 
            Kernel: Linux 5.3.0-26-generic

What's wrong?

Best regards.

This has been reported in pull request #892

@abelardolg @robocoder This has been implemented in the 2.0 branch of assetic-php/assetic. Until we tag 2.0, you can pull it in by using "assetic/framework": "dev-2.0/dev" in your composer.json files.

@LukeTowers , I have added these two lines inside my composer.json:

"scssphp/scssphp": "^1.0.6",
        "assetic/framework": "dev-2.0/dev"

Previously, I deleted var/cache, logs, composer cacheclear and vendor dir but it still continues showing me the same message.

Should I add some lines more inside another file (e.g. AppKernel)?

Any help would be welcome. Best regards.

[LukeTowers]

@abelardolg what's the full stack trace? Are you using ScssFilter? Do you still have kriswallsmith/assetic included?

See https://github.com/assetic-php/assetic/blob/2.0/dev/src/Assetic/Filter/ScssFilter.php

[abelardolg]

Thanks for your tips.
The full stack trace is attached.
Yes, I am using ScssFilter.
I have added kriswallsmith/assetic (kriswallsmith/assetic: "1.4.0").

I commented the line where I inserted the reference to this package:
kriswallsmith

but it still continues with the same issue:

Best regards.

[LukeTowers]

@abelardolg you need to remove the kriswallsmith reference from your composer and run composer update. If it's still present at all it will cause issues.

[abelardolg]

@LukeTowers : thanks for your comment but I proceed to run the above steps but this time I run composer update (instead of composer install) but nothing happens: it remains same issue.

[LukeTowers]

@abelardolg please post your current composer.json

[abelardolg]

composer.txt
Best regards.

[abelardolg]

Anybody could help me with this issue, please?
Thanks in advance.

Best regards.

[LukeTowers]

@abelardolg the problem is that you're using symfony/assetic-bundle which pulls in this current library instead of the updated fork: https://github.com/symfony/assetic-bundle/blob/master/composer.json#L21.

You can try adding "assetic/framework": "dev-2.0/dev as 1.4" to your composer.json require property near the top, although you'll have to wait for @jaxwilko to update the name of the ScssFilter to ScssphpFilter.

[abelardolg]

Ok, then I'll wait to download that library...when it is available.

Thanks for your help, time and effort.

Best regards.

[jaxwilko]

@LukeTowers @abelardolg the ScssFilter change has been merged into 2.0/dev :)

[abelardolg]

Hi,

According to my attached composer.txt, what changes should I do?

Best regards.

[LukeTowers]

@abelardolg

try adding "assetic/framework": "dev-2.0/dev as 1.4" to your composer.json require property near the top

@jaxwilko can you submit a PR to the october rain library to update the reference? To the wip/laravel-6 branch please.

[abelardolg]

I added that library on the top:

"roave/security-advisories": "dev-master",

but it nothing solves.

[LukeTowers]

@jaxwilko I think we might have to update the replace property of composer.json to reference 1.4 instead of *

[LukeTowers]

@abelardolg We've just released the 2.0 release that addresses a number of existing issues and dependency updates, see https://github.com/assetic-php/assetic/releases/tag/v2.0.0 for more information! Please try it out and let us know if you have any issues!
