【中文标题】安装 RVM 后无法加载 Sass / Compass，与 Symfony2 中的 Assetic 一起使用【英文标题】：Unable to load Sass / Compass after installing RVM, to use with Assetic in Symfony2 【发布时间】：2012-07-29 22:18:52 【问题描述】：我尝试使用 Capifony，它需要 Capistrano，它需要 Ruby。但是我的 ruby apt 版本很旧，并且会抛出语法错误。然后我安装了 RVM 并这样做了：
$ 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
将这些路径复制并粘贴到 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，关于 Compass 和 Sass 的一切都运行良好。 Compass/Sass 似乎仍然可以从 app_dev.php 工作，但是当我尝试转储资产进行生产时它们会中断：
$ 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.

我想添加更多标签：compass 和 sass。不知道能不能高分。
更新
我添加了一个这样的包装器：
$ rvm wrapper ruby-1.9.3-p194@myapp php sass compass
并再次编辑了 config.yml，但现在我会随机交替出现这些错误：
错误 1：
[Assetic\Exception\FilterException]
An error occurred while running: '/usr/local/rvm/rubies/ruby-1.9.3-p194/bin/ruby' '/usr/local/rvm/bin/php_compass' 'compile' '/tmp' '--config' '/tmp/assetic_compass0Tmn8t' '--sass- dir' '' '--css-dir' '' '/tmp/assetic_compasssw2S3k.scss'
Error Output: /usr/local/rvm/rubies/ruby-1.9.3-p194/bin/ruby: no Ruby script found in input (LoadError)
Input:

body

错误 2：
Error Output: /usr/local/rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.1.5/lib/bundler/shared_helpers.rb:22:in `default_gemfile': Could not locate Gemfile (Bundler::GemfileNotFound)
from /usr/local/rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.1.5/lib/bundler.rb:213:in `default_gemfile'
指南针通过 app_dev.php 仍然可以正常工作
【问题讨论】：
【参考方案1】：解决方案
只需使用lessphp。可以用 Composer 安装，然后在 config.yml 中：
lessphp:
php: %kernel.root_dir%/../vendor/leafo/lessphp/lessc.inc.php
apply_to: "\.less"
【讨论】：
@alex88 我试过了，真的。我过去使用过 ruby 和 rails。 ruby 废话就够了，php + less 就赢了。 哦，当然 :) 我也是，有时它可能是一个 PITA.. 缺少的一个很好的东西是精灵生成 :)【参考方案2】：我猜你需要一个包装器：
rvm wrapper ruby-1.9.3-p194@myapp php sass compass
这将生成调用适当的 ruby(rvm) 环境的包装器，像这样使用它们：
sass:
bin: /usr/local/rvm/bin/php_sass
#apply_to: "\.scss$"
compass:
bin: /usr/local/rvm/bin/php_compass
apply_to: "\.scss$"
【讨论】：
谢谢，我试过了，但它抛出了另一个错误，我更新了我的帖子 这完全是随机的，现在它显示“无法找到 Gemfile (Bundler::GemfileNotFound)”。看起来像一个指南针错误，因为我没有使用 Bundler。 第二个错误尝试gem uninstall rubygems-bundler - compass 中有一个错误，当与rubygems-bundler 连接时可能会生成此错误以上是关于安装 RVM 后无法加载 Sass / Compass，与 Symfony2 中的 Assetic 一起使用的主要内容，如果未能解决你的问题，请参考以下文章
