Sass import error in Rails 3 app - "File to import not found or unreadable: compass"
提问by Eric Wright
I have a Rails 3 app on which I successfully ran compass init rails ./ --using blueprint. I can @importfiles from the /stylesheets directory, but I get an error when I try to @import compass.
我有一个成功运行的 Rails 3 应用程序compass init rails ./ --using blueprint。我可以@import从 /stylesheets 目录中创建文件，但是当我尝试@import compass.
Right now the app has two simple sass files:
现在该应用程序有两个简单的 sass 文件：
common.scss
常见的.scss
$body-background: blue;
main.scss
主文件
@import "common";
//@import "compass";
body {
background: $body-background;
}
With the @import "compass"line commented out, this works -- I get a blue background, so I know Sass is working.
@import "compass"注释掉该行后，这行得通——我得到了蓝色背景，所以我知道 Sass 正在工作。
If I uncomment the line, and try to import compassor blueprintor anything else, I get an error like this.
如果我取消注释该行，并尝试导入compass或blueprint其他任何内容，我会收到这样的错误。
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: }
I had through maybe I had to explicitly tell Sass where to find the Compass gem, so I added an add_import_pathline to config/compass.rb:
我已经完成了，也许我必须明确告诉 Sass 在哪里可以找到 Compass gem，所以我add_import_path在 config/compass.rb 中添加了一行：
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 have been googling for two days, and can't determine why I'm having this problem with basic @importstatements. How do I tell Sass where to find the Compass and Blueprint libraries?
我已经用谷歌搜索了两天，无法确定为什么我的基本@import语句会出现这个问题。我如何告诉 Sass 在哪里可以找到指南针和蓝图库？

Okay, after help from the amazing Chris Eppstein I was able to find the offending line. In config/environments.rbI had this line:
好的，在令人惊叹的 Chris Eppstein 的帮助下，我找到了违规行。在config/environments.rb我有这条线：
Sass::Plugin.options[:template_location] = {
"#{RAILS_ROOT}/app/stylesheets" => "#{RAILS_ROOT}/public/stylesheets"
}
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].
对于当前版本的 Rails（我有 3.0.7）和 Compass（0.11.1），这条线不是必需的。我是按照教程添加的。如果 sass 找不到指南针，那可能是因为这条线把你的Sass::Plugin.options[:template_location].

I was getting this error.
我收到这个错误。
I changed this line in my application.rb from:
我将 application.rb 中的这一行从：
Bundler.require(:default, Rails.env) if defined?(Bundler)
to:
到：
Bundler.require(*Rails.groups(:assets => %w(development test))) if defined?(Bundler)
Also, make sure the files are names something.css.sassNOT something.sass
另外，请确保文件的名称为something.css.sass 而不是something.sass
And one other thing, I had an old compass.rb file in my config directory which isn't needed in Rails 3.2. Deleting that also solved this problem for me.
还有一件事，我的 config 目录中有一个旧的 compass.rb 文件，Rails 3.2 不需要它。删除它也为我解决了这个问题。

I fixed this problem by switching to the compass-railsgem instead of the compassgem in my Gemfile (don't forget to reboot your server). Just in case someone might come across here.
我通过在我的 Gemfile 中切换到compass-railsgem 而不是 gem 来解决这个问题compass（不要忘记重新启动你的服务器）。以防万一有人遇到这里。

I commented this line in my application.rb from:

and uncommented:
并取消注释：
Bundler.require(:default, :assets, Rails.env) if defined?(Bundler)

I fixed this problem on my Rails 3.2.0 server by moving out gem 'compass-rails', '~> 1.0.1'from the :assetsgroup in the Gemfile, from a tip in https://github.com/Compass/compass-rails/issues/19.
我通过gem 'compass-rails', '~> 1.0.1'从https://github.com/Compass/compass-rails/issues/19 中的提示移出中的:assets组，在我的 Rails 3.2.0 服务器上解决了这个问题。Gemfile

The @import command in Sass imports .scss or .sass files, not .css files.
Sass 中的 @import 命令导入 .scss 或 .sass 文件，而不是 .css 文件。
It looks like something was missed in the install. (maybe the line compass install blueprint?) I followed the steps here:
http://compass-style.org/reference/blueprint/and was unable to recreate the issue.
看起来安装中遗漏了一些东西。（也许是线路compass install blueprint？）我按照以下步骤操作：http:
//compass-style.org/reference/blueprint/并且无法重现该问题。

This was after updating a project from 3.0.3 to 3.2.13
这是在将项目从 3.0.3 更新到 3.2.13 之后
