安装RVM后无法加载Sass / Compass，无法与Symfony2中的Assetic一起使用

Question

I was trying to use Capifony, which requires Capistrano, which requires Ruby. But my apt version of ruby was old and was throwing syntax errors. So then I installed RVM and did this:

$ 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

Copied and pasted those paths to 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$"
    compass:
        bin: /usr/local/rvm/gems/ruby-1.9.3-p194@myapp/gems/compass-0.13.alpha.0/bin/compass
        apply_to: "\.scss$"

Everything about Compass and Sass worked fine before switching to RVM. Compass/Sass still seem to work from app_dev.php, but they break when I try to dump assets for production:

$ 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.

Related: @mpapis @jamz Sass broken after install with RVM, using Assetic PHP

I would like to add more tags: compass and sass. Not sure if can be done with higher score.

UPDATE

I added a wrapper like this:

$ rvm wrapper ruby-1.9.3-p194@myapp php sass compass

And edited config.yml again, but now I get these errors alternated, randomly:

Compass still works fine through app_dev.php

Answer 1

I guess you need a wrapper:

rvm wrapper ruby-1.9.3-p194@myapp php sass compass

this will generate wrappers which will call proper ruby(rvm) environment, use them like:

sass:
    bin: /usr/local/rvm/bin/php_sass
    #apply_to: "\.scss$"
compass:
    bin: /usr/local/rvm/bin/php_compass
    apply_to: "\.scss$"

Answer 2

Solution

Just use lessphp . It can be installed with Composer, and then in config.yml:

    lessphp:
         php: %kernel.root_dir%/../vendor/leafo/lessphp/lessc.inc.php
         apply_to: "\.less"
