In my team we have the same version of Compass (it`s Compass 0.12.2 Alnilam). When Compass compiles my SCSS the color code is changed from uppercase (#A0CAE3) to lowercase (#a0cae3) in the SCSS. Only I have this problem, other developers have the uppercase color code. Why?
Is should check version of "sass".
sass -v
Sass version 3.1.15 works fine in my case. Uninstall all installed "sass" versions with
gem uninstall sass
and install 3.1.15 version
gem install sass -v 3.1.15

I tried to upgrade from Bootstrap 4 Alpha 6 to 4.0.0 final version for my Rails 5 project, I'm sure the v4.0.0 gem has been installed (I also uninstalled the alpha version gem), but when I run my project (dev mode), I found the generated Bootstrap CSS files are still based on the Alpha version.
gem 'bootstrap', '~> 4.0.0'
Other than uninstalling the old gem and install the new bootstrap gem, do I need to do anything else for the upgrade? Download the physical v4.0.0 files and replace the old files in my project?
You can have look at this article:
How to update a single gem conservatively
Option 1
This will work if all dependencies for the update are already satisfied.
Find out the version you want to update to
Change it directly in Gemfile.lock
Run bundle install and see if that worked
Option 2
This will work if the gem has no shared dependencies with other gems.
Find out the version you want to update to.
Add that version explicitly to the Gemfile with , '=1.2.3'
Run bundle install
Remove the explicit version number again
Run bundle install once more
Option 3
This should always work.
Run bundle update GEMNAME
Run git diff Gemfile.lock and notice all the updates you didn't want
Revert the unwanted changes to Gemfile.lock you don't want (manually or by staging changed lines one-by-one), leaving only the desired updates.
Run bundle install and see if that worked
Option 4
There are persistent rumors that you can update a single gem by calling bundle update --source GEMNAME. However no one seems to know how and why this works, it's not a documented feature of Bundler. It might be an unintended side effect of something else.
I believe this command will try to update GEMNAME and GEMNAME only. If this leads to unmatched dependencies to other locked gems, it will fail.
If you use this option, be sure to git diff your Gemfile.lock to see if the changes are what you expected.
Option 5
Bundler >= 1.14 has a --conservative flag. Using the conservative flag allows bundle update GEM to update the version of GEM, but prevents Bundler from updating the versions of any of the gems that GEM depends on.

Try to keep Ruby dependencies in your Gemfile and JS/CSS ones elsewhere. Node+Yarn is a good way to do that.
If not already there
brew install yarn
Then in config/initializers/assets.rb
Rails.application.config.assets.paths << Rails.root.join('node_modules')
Now you can do this in your console:
yarn add bootstrap
It should have create a node-modules directory if not already there.
Then just add bootstrap to your JS/SCSS files
JS
//= require bootstrap/js/src/index
CSS
#import "bootstrap/scss/bootstrap";
I have just upgraded to Sass 3.3 so that I can use some of the new features (BEM styled class names, mappings, #at-root, etc). If I compile my project with Sass (via sass --watch), it works just fine. However, if I compile it using Compass (via compass watch), I get an error when using the new Sass features.
I'm using Compass 0.12.
Compass 0.12 explicitly depends on Sass 3.2. Even if you have a newer version of Sass installed, it will still compile with 3.2. In order to use Sass 3.3 or later, you have to be using Compass 1.0 or later.
Running the gem install command normally should get you the latest stable version.
gem install compass
At the time this question was asked, Compass 1.0 was still in beta. To install the latest beta version of a gem, you will need to install it using the --pre flag.
gem install compass --pre
Note that you do not need to install Sass first in order for this to work. Installing Compass will automatically install the latest version of Sass that it is compatible with.
I have Compass 1.0 installed and it still errors
Double check any other dependencies you might have (Compass extensions, etc.), one of them might be specifying an older version of Sass or Compass.
If you're using an application or build tool rather than using the commands directly, make sure they're not referencing older versions of Compass.
Windows users
As a Window user, I got an error when I tried to watch my project using the newer Compass.
LoadError on line ["36"] of C: cannot load such file -- wdm"
To fix that problem:
You must install the ruby DevKit:
Download found here: http://rubyinstaller.org/downloads/
Follow this page to properly install:
https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
Now install wdm:
gem install wdm
There didn't seem to be any one place that contained the whole list of steps required, in order, to make this work, so here they are. This list is for Windows, but it may work fine on other platforms.
Install Ruby -- use 1.9.3 -- http://rubyinstaller.org/downloads .
Download the Ruby DevKit found lower on the same page -- http://rubyinstaller.org/downloads/
run it to extract it somewhere (permanent). Then cd to it, run “ruby dk.rb init” and “ruby dk.rb install” to bind it to ruby installations in your path.
gem install wdm
gem install sass
gem install compass --pre
It now is, in the latest version of Compass. Update compass to get the changes and work with Sass 3.3 and higher
Current Sass compatibility can be found here: https://rubygems.org/gems/compass
To upgrade just run
$gem install compass
I am working on a project based on ruby. How can I update the SASS engine? My PC has one version, but my project doesn't.
I've tried using gem update, but it doesn't update SASS.
Any help?
If you are using bundler, you can just run
bundle update sass
Without bundler rubygems can install fresh version, but your app may use old one. Try to uninstall older version.
But the best solution to escape such problems - is to use bundler.
I've been using sass and compass on this computer for a few months with no issues.
Additionally, my config.rb and sass directories have always been set up the same way, and they're the same on all of my projects.
Recently, I started getting this error in Sublime when I build the sass: Sass::SyntaxError: File to import not found or unreadable: compass.
The first line of my .scss file is #import "compass";, so I see this error in Terminal: error sass/style.scss (Line 36 of _vertical_rhythm.scss: Incompatible units: 'px' and 'em'.)
I've been searching for days, and I see answers around some of this stuff (the vertical-rhythm specifically), but nothing is my exact problem, and I can't find a solution.
My compass version is 0.12.5 (Alnilam), and my sass version is 3.3.4 (Maptastic Maple).
At work, everything compiles fine with the exact same files, working from the exact same GitHub repo. I need to check my versions of compass and sass at work tomorrow, but in the meantime, I'm stumped.
Any ideas? Has this happened to anyone?
After a month of troubleshooting, the solution ended up being simpler than expected.
I uninstalled all versions of both Sass and Compass, and then I installed the latest Compass and let it install Sass automatically.
So after doing sudo gem uninstall compass and sudo gem uninstall sass, I did sudo gem install compass. That installed both Compass and its dependencies (Sass version 3.2.19). (I'm on a Mac, so I had to use sudo.)
Solved!

I am working with sass and compass and trying to use the new sourcemap feature as Chrome 27 requires the new method of sourcemap to show the actual sass files and line numbers in the chrome console panel.
I am able to run the following sass command sass --sourcemap --watch style.scss:style.css
however if I append the --compass argument like the following sass --compass --sourcemap --watch style.scss:style.css
I get the following error in the windows cmd panel: "ERROR: Cannot load compass".
I have tried following some of methods that apparently worked for some people on the github issue page https://github.com/chriseppstein/compass/issues/1108
The methods I have tried are using the sass 3.3.0.alpha.177 with compass 0.12.2 (this producers an error every time I try and execute the compass gem which is almost identical to this issue Why does "compass watch" say it cannot load sass/script/node (LoadError)?)
Currently my setup is the following:
sass 3.3.0.alpha.177
compass 0.13.alpha.4
Windows 7
Is there a way that I can use Sass with compass and at the same time generate the sourcemaps which are needed for css debugging?
I found that I had two versions of Sass installed (3.4.25 and 3.5.5). I was getting the error when using grunt which was using the latest version 3.5.5. I resolved the problem by uninstalling 3.5.5.
gem uninstall sass
→
Select gem to uninstall:
1. sass-3.4.25
2. sass-3.5.5
3. All versions
Works with Sass 3.3.0.alpha.149 and compass 0.12.2 on windows 7
The versions mentioned by #lollerskates666 work, but I had to specifically remove sass version 3.3.4 which came down when I installed compass.
If anyone else if having this difficulty, I had to run the following rules to get it working:
gem install compass --version 0.12.2
This installs compass and also Sass 3.3.4 (Maptastic Maple). These two versions, combined with --sourcemap don't seem to play nicely, so you'll need to install an older version of Sass:
gem install sass --pre --version 3.3.0.alpha.149
Although you've now installed it, if you run:
sass --v
Ruby will still be using Sass version 3.3.4, so you'll need to uninstall this version:
gem uninstall sass
**Select number assigned to version 3.3.4**
Now, if you run:
sass --v
You should see:
Sass 3.3.0.alpha.149 (Bleeding Edge)
Sass should now work with the compass lib and also produce sourcemaps, which Chrome can read :)
I run this command to watch my scss files:
sass --watch --sourcemap --compass --style compressed scss:css
Hope this helps!!
** I'm running this on a Mac, but the same versions work fine :)
Had this problem as well. gem 'sass', '~> 3.2.19' was working on a previously created application. I resorted to using that instead of gem 'sass', '~> 3.4.16 which was automatically generated at creation time for a 3.2.22 app and which generated this problem.
So there does appear to be an issue with the version.
