Warning: Running "compass:server" (compass) task

Question

I had ruby install @squiroid. I forget to run gem install compass. That worked for me.

I've the same problem in ubuntu and I did this to solve my problem :

1. sudo apt-get install ruby
2. sudo apt-get install ruby-compass
3. sudo gem install compass

after that grunt serve works

I had the same problem I installed compass gem on my desktop and it is resolved.

If you're on OS X or Linux you probably already have Ruby installed; test with ruby -v in your terminal. When you've confirmed you have Ruby installed, run gem update --system && gem install compass to install Compass and Sass.

For windows you can download ruby and then install compass.

Hope it helps :)

I searched and searched ... until finally I got the answer to this problem.
In my case it happened when I was creating a new angularjs application with yeomen.

This answer is specific to windows users

Step 1: Install ruby http://rubyinstaller.org/downloads/

Step 2 : download rubygems Link : https://rubygems.org/rubygems/rubygems-2.6.8.zip

Step 3 : unzip rubygems-2.6.8.zip

Step 4 : open powershell (terminal/command line) to the rubygems-2.6.8 folder path.(location of the folder eg. c:\folder\folder)

Step 5 : in the powershell terminal run these commands

> ruby setup.rb

> gem install compass

enjoy!

I had the same problem

"yo angular" with sass option will use the compass, which is a ruby gem.

Install the ruby, and the compass

In windows system we also need to set the path of ruby. Add the ruby/bin to path

Then "grunt serve" works!
