编译单个样式表时出现Compass错误："；单个样式表必须位于sass目录中；

使用Compass编译单个样式表时遇到问题。我可以使用

compass compile

执行所有文件，并使用

compass watch

监视更改。但是，当我尝试将特定文件分配给compass compile时，会出现以下错误：

单个样式表必须位于sass目录中

我的目录结构：

project root
- util
-- compass
--- config.rb
- www
-- css
--- [destination for .css files]
-- sass
--- [.scss files]

My config.rb：

project_type = :stand_alone

# Set this to the root of your project when deployed:
project_path = "../../"
http_path = "www"               # The path to the project when running within the web server.
css_dir = "www/css"         # relative to project_path
sass_dir = "www/sass"       # relative to project_path
images_dir = "www/images"   # relative to project_path
javascripts_dir = "www/js"  # relative to project_path

# You can select your preferred output style here (can be overridden via the command line):
# output_style = :expanded or :nested or :compact or :compressed
output_style = :compressed

# To enable relative paths to assets via compass helper functions. Uncomment:
relative_assets = true

# generate sourcemaps
sourcemap = true

从

/util/compass

文件夹运行时，以下各项工作正常：

compass compile
compass watch

这些方法不起作用：

compass compile builder.scss
compass compile ../../www/sass/builder.scss
compass compile www/sass/builder.scss

并导致错误，这可能意味着无法找到scss文件

我做错了什么？

这不是一个完美的解决方案，但至少能让你继续前进。这可能是由于compass中的某些错误导致无效的

sass\u路径

。因此，手动设置

sass_路径

，如下所示：

project_type = :stand_alone

# Set this to the root of your project when deployed:
project_path = "../../"
http_path = "www"               # The path to the project when running within the web server.
css_dir = "www/css"         # relative to project_path
sass_dir = "www/sass"       # relative to project_path
sass_path = File.expand_path(File.join(project_path, sass_dir))
images_dir = "www/images"   # relative to project_path
javascripts_dir = "www/js"  # relative to project_path

# You can select your preferred output style here (can be overridden via the command line):
# output_style = :expanded or :nested or :compact or :compressed
output_style = :compressed

# To enable relative paths to assets via compass helper functions. Uncomment:
relative_assets = true

# generate sourcemaps
sourcemap = true

然后，您应该能够使用命令

compass compile../。/www/sass/builder.scss
