I'm new dev environments and to get to grips with sass. I've installed compass and a few other gems, Im trying to use live reload to help update the browser, but it won't play nice;
LoadError on line ["55"] of /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb: cannot load such file -- compass/import-once/activate
Run with --trace to see the full backtrace
screen.scss: compilation failed.
I'm not sure what's happening here, could any one shed a little light on the subject and preferably point me to a good resource?
Resolved the issue after a little more googling;
LiveReload plugin
Hopefully this ill help anyone else stuck in the same boat :)

I am currently working on a personal project using the Ruby language in Cloud9 IDE. Recently, I came across an environment/programming language called Processing. My goals is to make Processing available for my use in Cloud9 IDE.
I am a complete novice and have no clue what I am doing. I followed directions from the following website: Directions for setting up Processing
I entered the following commands into Cloud9's terminal:
rvm install jruby
rvm use jruby
gem install ruby-processing
PROCESSING_ROOT: "/Applications/Processing.app/Contents/Java"
Entering in PROCESSING_ROOT: "/Applications/Processing.app/Contents/Java"
outputted message bash: PROCESSING_ROOT:: command not found
I wasn't too surprised by this, since the last entry probably needs information specific to my setup. Here are my questions:
1.) Are these directions correct for what I am trying to do? (get Processing to work in Cloud9 IDE). If they are not correct, can someone please point me to the correct directions, or give me directions?
2.) If these directions are correct, how can I successfully finish the last step? I tried running DrawRuby.rb, a simple program copied from the internet that supposedly made use of Processing. When I ran the code, the message "You need to set PROCESSING_ROOT in ~/.rpsrc" appeared. I am not sure if this piece of information is relevant or not, but I figured I would add it.
This is where I am at, and I am completely stuck. If someone could give me some help, I would be very grateful. Also, please make your explanation easy to understand. I am relatively new to the programming world, and may not necessarily understand terminology or how things should work.
Cheers!
*** Edit: I created a new workspace in Cloud9 IDE and tried Jed's suggestion. This is what happened:echo 'PROCESSING_ROOT: "/Applications/Processing.app/Contents/Java"' > ~/.rpsrc
:~/workspace $ rp5 run Draw.rb

You need to add a file to your home directory (~/) called .rpsrc and then add that environmental setting (PROCESSING_ROOT) to your file. The following should work from the command line in your cloud9 environment:
echo 'PROCESSING_ROOT: "/Applications/Processing.app/Contents/Java"' > ~/.rpsrc
I know it might be a bit late for you but ruby-processing is now deprecated, and will only work with processing-2.2.1. For processing-3.3.7 use either JRubyArt or propane latter does not even require processing install.
I am new to SASS. I am using this as a guide to learn Bourbon -
http://www.git-tower.com/learn/bourbon-neat-bitters/getting-ready/introduction
I followed all the instructions and it displays fine on my local machine. But when I edit _layout.scss, it doesn't compile to styles.css. I installed Compass and had it watch the project folder, but same results. My changes won't take.
Am I missing a step?
This is likely more of a sass importing/file-name issue than anything specifically with bourbon. I'd check out http://sass-lang.com/guide . Sass-lang put together a really nice guide to sass that includes things like imports, etc.
Also, Compass app can bring some things to the party that can conflict with Bourbon. I'd recommend using the sass app or a desktop app like https://prepros.io which can be easier starting out.
Hope this helps 🍻
first question and a rails newly (so take it easy on me)...
It appears my rails application is not loading it's assets in production, I have searched endlessly and tried nearly every suggestion and I have had no such luck.
At this point, I do not even know what information to provide to help anyone diagnose the problem so here is my github like: https://github.com/jz-ziegler/develapp
Let me now if anything else is needed, thanks!
I have an issue with compass Im not able to find out.
Every time I compile, when compass find a intruction like:
#import "base-icons/*.png";
Compass throw:
WARNING: Compass::SpriteImporter should define the #public_url method.
Actually, it compiles and everything is working fine.
Unfortunately, I cannot find information about this issue, and I hate to see warnings on my console.
Anyone know what could be happening ? How can I get rid of this ? Or which are the consequences of this message, what does it mean ?
Thanks in advance !
The issue is reflected here:
https://github.com/chriseppstein/compass/issues/1108
And solved on the release tagged as: "import-once-1.0.4"
I recently changed an image on the landing page of my herokuapp built in rails. I realized that everything worked fine except that the landing page threw a 500 error. Upon some research I realized i should run RAILS_ENV=production bundle exec rake assets:precompile
After doing so, the images and some of the styling came back but some of it is still screwy and I cannot understand why.
I've read through just about every stackoverflow thread, the rails guide on the asset pipeline, and others but I can't get it to work. I've amended the files that need amending
as far as I know but nothing is working to make the styling revert to how it should be.
However, on the rails guide it notes that there are two caveats to locally precompile:
You must not run the Capistrano deployment task that precompiles
assets. You must change the following two application configuration
settings. In config/environments/development.rb, place the following
line:
config.assets.prefix = "/dev-assets"
I did the change within development.rb but I am not sure on how I can not run Capistrano. I dont think I'm doing that so maybe it's throwing some things off - idk, but each time I try to recompile now, the rake aborts. Any help is very much appreciated.
