Rails 3应用中的Sass导入错误-“找不到要导入的文件或不可读的文件：指南针”

问题描述

我有一个Rails 3应用程序，在该应用程序上我成功运行了 compass init rails ./-使用蓝图。我可以从/ stylesheets目录中 @import 文件，但是当我尝试 @import罗盘时出现错误。

I have a Rails 3 app on which I successfully ran compass init rails ./ --using blueprint. I can @import files from the /stylesheets directory, but I get an error when I try to @import compass.

现在该应用程序具有两个简单的sass文件：

Right now the app has two simple sass files:

common.scss

$body-background: blue;

main.scss

@import "common";
//@import "compass";

body {
  background: $body-background;
}

使用 @import compass 行注释掉了，这行得通-我的背景是蓝色的，所以我知道Sass在工作。

With the @import "compass" line commented out, this works -- I get a blue background, so I know Sass is working.

如果我取消注释该行，然后尝试导入罗盘或蓝图或其他任何东西，我得到这样的错误。

If I uncomment the line, and try to import compass or blueprint or anything else, I get an error like this.

Syntax error: File to import not found or unreadable: compass.
              Load paths:

                /Users/eric/path/to/myrailsapp/app/stylesheets
        on line 2 of /Users/eric/path/to/myrailsapp/app/stylesheets/main.scss

1: @import "common";
2: @import "compass";
3:
4: body {
5:  background: $body-background;
6: }

我曾经经历过，也许我不得不明确地告诉Sass在哪里找到指南针gem，所以我在config / compass.rb中添加了 add_import_path 行：

I had through maybe I had to explicitly tell Sass where to find the Compass gem, so I added an add_import_path line to config/compass.rb:

require 'compass'
require 'html5-boilerplate'

project_type = :rails
project_path = RAILS_ROOT if defined?(RAILS_ROOT)
add_import_path "/Library/Ruby/Gems/1.8/gems/"  # unfortunately this has no effect

http_path = "/"
css_dir = "public/stylesheets"
sass_dir = "app/stylesheets"
images_dir = "public/images"
javascripts_dir = "public/javascripts"
cache_dir = "tmp/sass-cache"

http_images_path = "/images"
http_stylesheets_path = "/stylesheets"
http_javascripts_path = "/javascripts"

I已经搜寻了两天，无法确定为什么我在基本的 @import 语句中遇到了这个问题。

I have been googling for two days, and can't determine why I'm having this problem with basic @import statements. How do I tell Sass where to find the Compass and Blueprint libraries?

推荐答案

好吧，在出色的Chris Eppstein的帮助下，我是如何告诉Sass的？能够找到违规行。在 config / environments.rb 中，我有以下一行：

Okay, after help from the amazing Chris Eppstein I was able to find the offending line. In config/environments.rb I had this line:

Sass::Plugin.options[:template_location] = {
"#{RAILS_ROOT}/app/stylesheets" => "#{RAILS_ROOT}/public/stylesheets"
}

使用当前版本的Rails （我有3.0.7）和指南针（0.11.1），此行不必要。我在完成教程后添加了它。如果sass找不到指南针，可能是因为这行弄乱了您的 Sass :: Plugin.options [：template_location] 。

With the currently versions of Rails (I have 3.0.7) and Compass (0.11.1) this line is not necessary. I added it after following a tutorial. If sass can't find compass, it might be because this line is messing up your Sass::Plugin.options[:template_location].
