 * Be careful when using less this way, might be most straight forward, but  
 assetic doesnt check the included files                                     
 * for changes, and will only regenerate the css if it detects changes in t

 * But then assetic will compile each less file in a own compiler session s  
o you cant mix in the less style into bootstrap, which might not be OK

// if you have any variables.less file INCLUDE IT AFTER EVERYTHING cause re  
sponsive.less also overrides it with the one from bootstrap!!!!!

I don't understand what is the error come from. I tried to search for this error but none of the solutions is work

This is my twig file

{% block stylesheets %}
    {{ parent() }}
    {% stylesheets 
        filter='cssrewrite,?yui_css'
        'bundles/mopabootstrap/css/mopabootstrapbundle.css'
    %}
        <link href="{{ asset_url }}" rel="stylesheet" type="text/css" />
    {% endstylesheets %}
{% endblock %}

Answer 1

I had the same error with mopabootstrap bundle. The command php app/console mopa:bootstrap:symlink:less , used to install symlink, is correctly creating a symlink in vendor/mopa/bootstrap-bundle/Mopa/Bundle/BootstrapBundle/Resources, but the bootstrap.less file is still not found.

So I fixed it by copying the vendor/twbs/bootstrap folder in vendor/mopa/bootstrap-bundle/Mopa/Bundle/BootstrapBundle/Resources. It's not a really proper solution, but at least I can dump the assets.

Answer 2

@Kevin is correct here is the demo solution for what Kevin has given:

php app/console mopa:bootstrap:symlink:less

Initializing composer ... done.

Checking symlink ... not existing

Creating symlink: /var/www/carsing/vendor/mopa/bootstrap-bundle/Mopa/Bundle/BootstrapBundle/Resources/public/bootstrap

for target: ../../../../../../../twbs/bootstrap ... OK

As you can see mopa bundle needs (a link to) bootstrap.

And now php app/console assetic:dump works without error at all.
