Problem importing and parsing bower_component

[edvanleeuwen]

After upgrading from 8.9.0 tot 9.1.0, I get the following error executing composer update just after the last step (compiling Greenwhich css).
Reverting to 8.9.0 works.

`> @php -r 'require_once '''/home/myuser/domains/o.mydomain/public_html/vendor/autoload.php'''; Civi\CompilePlugin\TaskTransfer::import(); \CCL::copy('''../../bower_components/select2/select2-bootstrap.css''', '''extern/select2/select2-bootstrap.scss''');'

@php -r 'require_once '''/home/myuser/domains/o.mydomain/public_html/vendor/autoload.php'''; Civi\CompilePlugin\TaskTransfer::import(); \CCL\Tasks::scss($GLOBALS[\Civi\CompilePlugin\TaskTransfer::GLOBAL_VAR]);'

@edvanleeuwen Thanks for taking the time to report this!

This looks like some code gets automatically executed after a composer dumpautoload, and that this code (or some dependency) is not compatible with PHP-CSS-Parser V9.

If I read your code correctly, the problem lies in the https://github.com/padaliyajay/php-autoprefixer package, which has PHP-CSS-Parser as a dependency using the "death star version constraint".

So, if I see this correctly, this is not a bug in PHP-CSS-Parser, but an issue in said library. I recommend filing two issues there:

1. switch from the death star version constraint to a proper version for the dependency
2. fix compatibility with PHP-CSS-Parser V9

Please feel free to reopen this issue if you find out that this actually is a bug in our library.

This issue should be fixed in version 1.5 of php-autoprefixer. You may need to change your composer.json to use that version.

Thanks for your help! The 1.5 version only works with the dev version 6.10 of CiviCRM. I will wait for the stable version.
