无法在symfony2中设置Lessphp

Question

以下从this thread我被要求尝试实施lessphp以查看它是否与商业应用程序的当前版本兼容（它最初开发时并不是这样）。

伊夫安装的软件包与作曲家和成功如下设置配置按指令：

filters: lessphp: file: %kernel.root_dir%/../vendor/leafo/lessphp/lessc.inc.php apply_to: "\.less$" # Formatter options: compressed, lessjs, classic formatter: "compressed" preserve_comments: false

伊夫证实，少主类加载罚款良好的醇”死声明。

但当我试图assetic/dump时遇到以下错误。

Fatal error: Call to undefined method Assetic\Filter\LessphpFilter::setLoadPaths() in C:\Dropbox\xampp\htdocs\SBSonline\sbsonline-v2\app\cache\dev\appDevDebugProjectContainer.php on line 118

任何人都可以帮忙吗？我有一种感觉，我缺少明显的东西，但我无法找到它。

Answer 1

确实很奇怪。

根据的文档，应该有一个明显称为::setLoadPaths()的功能。

它没有在那里，所以我手动添加它。

它现在试图解析文件。
