我试图使用Capifony，它需要Capistrano，它需要Ruby。但是我的ruby的apt版本已经过时了，并且出现了语法错误。然后我安装了RVM并这样做：
$ rvm use 1.9.3
$ rvm --rvmrc --create use 1.9.3@myapp
$ gem install sass [--pre]
$ gem install compass [--pre]
$ updatedb
$ locate sass | grep myapp | grep bin
$ locate compass | grep myapp | grep bin
复制并粘贴这些路径到config.yml
sass:
bin: /usr/local/rvm/gems/ruby-1.9.3-p194@myapp/gems/sass-3.2.0.alpha.277/bin/sass
#apply_to: "'.scss$"
compass:
bin: /usr/local/rvm/gems/ruby-1.9.3-p194@myapp/gems/compass-0.13.alpha.0/bin/compass
apply_to: "'.scss$"
在切换到RVM之前，Compass和Sass的一切都很好。Compass/Sass似乎仍然可以在app_dev.php中工作，但当我试图为生产转储资产时，它们就坏了：
$ rm -r app/cache/ # this is how I delete cache, any other way give me errors, even before having this compass problem. This have always worked fine. I removed the * because this code block was interpreting it as a comment
$ php app/console assetic:dump --env=prod --no-debug
Dumping all prod assets.
Debug mode is off.

相关：@mmpapis@jamz-Sass在使用RVM安装后损坏，使用Assetic PHP
我想添加更多标签：指南针和时髦。不确定是否可以用更高的分数完成。
更新
我添加了一个这样的包装：
$ rvm wrapper ruby-1.9.3-p194@myapp php sass compass
并再次编辑config.yml，但现在我得到这些错误交替，随机：
错误1:
[Assetic'Exception'FilterException]

Compass在app_dev.php 中仍然运行良好
我想你需要一个包装器：
rvm wrapper ruby-1.9.3-p194@myapp php sass compass
这将生成包装器，该包装器将调用适当的ruby（rvm）环境，像一样使用它们
sass:
bin: /usr/local/rvm/bin/php_sass
#apply_to: "'.scss$"
compass:
bin: /usr/local/rvm/bin/php_compass
apply_to: "'.scss$"
解决方案
只需使用lesstphp。它可以用Composer安装，然后在config.yml:中安装
lessphp:
php: %kernel.root_dir%/../vendor/leafo/lessphp/lessc.inc.php
apply_to: "'.less"
