安裝RVM后無法加載Sass / Compass，無法與Symfony2中的Assetic一起使用

Question

我試圖使用Capifony，它需要Capistrano，而后者需要Ruby。 但是我的Ruby apt版本過舊，並引發語法錯誤。 因此，我安裝了RVM並執行以下操作：

$ 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

將這些路徑復制並粘貼到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$"
    compass:
        bin: /usr/local/rvm/gems/ruby-1.9.3-p194@myapp/gems/compass-0.13.alpha.0/bin/compass
        apply_to: "\.scss$"

在切換到RVM之前，有關Compass和Sass的所有操作均正常。 Compass / Sass似乎仍然可以從app_dev.php運行，但是當我嘗試轉儲資產進行生產時，它們會中斷：

$ 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.

我得到的另一個錯誤：

相關：@mpapis @jamz 使用Assetic PHP與RVM安裝后，Sass斷開了

我想添加更多標簽：指南針和sass。 不知道是否可以用更高的分數來完成。

更新

我添加了一個這樣的包裝器：

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

並再次編輯config.yml，但是現在我交替出現這些錯誤：

指南針仍然可以通過app_dev.php正常工作

Answer 1

我想你需要一個包裝紙：

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

這將生成包裝，該包裝將調用適當的ruby（rvm）環境，如下所示使用它們：

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

Answer 2

解

只需使用lessphp即可 。 它可以與Composer一起安裝，然后在config.yml中安裝：

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