assetic:dump fails with ".pull-right is undefined: line: 60"

Question

I was trying to install the glyphicons locally rather than pulling from the CDN (which had stopped displaying them, for reasons I didn't investigate). Now running assetic:dump results in an exception I have no idea how to fix:

me@server:/var/www/blah$ php app/console assetic:dump -vvv
Dumping all dev assets.
Debug mode is on.

Any advice is greatly appreciated!

Answer 1

Turns out it's a bug in lessphp: https://github.com/leafo/lessphp/pull/478

Currently the solution is change the version in composer.json to:

"require": {
    "leafo/lessphp": "dev-master#85bd4557920d5f4fcbf41beb621e91b842e3621b"
}

but obviously this is just temporary. Thanks to milka in #symfony on freenode!

Answer 2

Checkout this reported bug on github. It looks like compressed files with a missing ; at the end are causing this behaviour. One solution would be to add it manually.

The suggested solution from me is to use uncompressed files to prevent this and also have more readable code in your dev environment. For the prod environment the files will be compressed by assetic anyway.

Answer 3

I'm pretty sure that I ran into this issue and determine that it was because of the Bootstrap LESS has variables defined in separate files and the Assetic LESS compiler doesn't play well with variables defined in a different file.
