Installing compass succeeds, but it is not accessible - ruby

(new to ruby here)
I am running on CrunchBang Linux statler.
I have uninstalled and reinstalled compass several times, just to make sure.
This is what I do:
» gem query
*** LOCAL GEMS ***
chunky_png (1.2.7)
fssm (0.2.10)
sass (3.2.5)
And then:
» sudo gem install compass
Successfully installed compass-0.12.2
1 gem installed
Installing ri documentation for compass-0.12.2...
Installing RDoc documentation for compass-0.12.2...
Let's check:
» gem query
*** LOCAL GEMS ***
chunky_png (1.2.7)
compass (0.12.2)
fssm (0.2.10)
sass (3.2.5)
And:
» gem which compass
/var/lib/gems/1.8/gems/compass-0.12.2/lib/compass.rb
But:
» compass
-bash: compass: command not found
So, what did I do wrong?

If you're using rbenv, run $ rbenv rehash.
Do this whenever you install a gem containing an executable (usually .../bin/<someExecutable>).

It seems gem is broken in Ubuntu. The following is needed:
PATH=/var/lib/gems/1.8/bin:$PATH

Can't install bundle - endless error message

This is what I'm using: Windows 8. Cygwin32. Rvm version 1.25.27. Ruby version 2.1.2p95. Gem version 2.3.0. Drush version 5.9.
I'm totally new to all this so it's very possible that the explanation is something really simple.
I tried to use "drush omega-guard" from my drupal theme folder but got an error saying I had to install Bundler version 1.2 or newer. This is all fine since I hadn't installed bundle. But when I try to use the command "bundle install" I get this:
$ bundle install
-bash: bundle: kommandot finns inte
(Kommandot finns inte = Command not found.)
When I try using "gem bundler install" I get this:
$ gem bundler install
ERROR: While executing gem ... (Gem::CommandLineError)
Unknown command bundler
I also tried "gem bundle install":
$ gem bundle install
ERROR: While executing gem ... (Gem::CommandLineError)
Unknown command bundle
So I used "which bundle" and then used cd to get to that folder.
$ which bundle
/home/I/.rvm/gems/ruby-2.1.2/bin/bundle
I tried the same commands again, but from the other folder, and ended up with this:
I#I ~/.rvm/gems/ruby-2.1.2/bin
$ gem install bundler
ERROR: While executing gem ... (TypeError)

I#I ~/.rvm/gems/ruby-2.1.2/bin

EDIT: Since I asked this question I tried reinstalling ruby 2.1.2. The installation stuck on "#importing gemset" and after about 36 hours my computer was turned of due to a blackout. I therefore don't know if the reinstallation was completed or not. After that I also changed my gem version to 2.1.2 to match the ruby version. Theese things seemed to help and afterwards I could run both "gem install bundler" and "bundle install". My gemlist now looks like this:
$ gem list

Unable to activate susy-2.1.1, because sass-3.2.17 conflicts with sass (~> 3.3.0)

I have installed the latest versions of compass, sass and susy. But still I am getting this error:
Unable to activate susy-2.1.1, because sass-3.2.17 conflicts with sass (~> 3.3.0)
Anyone knows how this Ruby thing works?
This is the list of my installed gems:
*** LOCAL GEMS ***
CFPropertyList (2.2.0)
chunky_png (1.3.0)
compass (0.12.4)
compass-core (1.0.0.alpha.19)
compass-import-once (1.0.4)
compass-rails (1.1.3)
fssm (0.2.10)
libxml-ruby (2.6.0)
multi_json (1.9.2)
nokogiri (1.5.6)
rb-fsevent (0.9.4)
rubygems-update (2.2.2)
sass (3.3.4, 3.3.3, 3.2.17)
sqlite3 (1.3.7)
susy (2.1.1)
gem install compass --pre
if you ended up uninstalling the sass 3.3.0 gem you should reinstall that first.
The best way without a doubt is to install Susy via the Compass Susy Plugin. This will avoid conflicts with other Compass projects that require the current version.
Commands:
gem install compass
gem install compass-susy-plugin
If you use Bundler, it will ensure that the gems in your Gemfile are the ones used by your project. So your Gemfile should specify "susy", "~>2.1.1" and "sass", "~>3.3.2", plus any other that you require, such as "breakpoint", "~>2.4.1". It then won't matter what versions are installed inside your Ruby gems folder. When you then do a 'bundle install', Bundler ensures that your project will only use the correct dependencies. This is, of course, a CLI instruction through the terminal. Alternatively, simply do a 'sudo gem uninstall sass -v 3.2.17', if you don't want to use Bundler.
I'm using Ubuntu server 14.04 and I had the same problem and this is what I have done
Remove all my gems with gem uninstall gemname
Install bundler with sudo apt-get install bundler
Create a Gemfile as #Remy said before. Here is a Getting Started With Bundler Guide
And finally bundle install
After that, bundler create a Gemfile.lock where are specified all the needed gems and its versions, so you can use it safely.

gem uninstall compass
gem uninstall sass

Can't install ffi 1.9.0 via rvm bundle install - OSX 10.8.4

Using OSX 10.8.4 on Macbook Pro with homebrew, xcode (with command line tools) and libffi.
I have installed rvm and ruby-1.9.3-p448 and have a gemset called omega.ecoop. There is a gemfile which lists gems that are required for this project. However, I can't get them installed, after running bundle check:
Bundler can't satisfy your Gemfile's dependencies.
This is correct as they are not installed. So I use:
bundle install
which produces the following:

Make sure that `gem install ffi -v '1.9.0'` succeeds before bundling.
This command does not work either (gem install ffi -v '1.9.0'), I get the same error. I tried:
sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
I have read:
can't setup ruby environment - installing fii gem error
Bundle update fails on ffi
Bundle update fails on ffi
Error installing ffi
gem install ffi -v '1.1.5' osx 10.8
Still no luck though. I followed this guide to set up RVM:
http://portertech.ca/2010/03/26/homebrew--rvm--awesome/
If this helps, ffi-1.0.11 installs without hitch, fff-1.9.0 will not install (http://rubygems.org/gems/ffi/versions).
/Users/Sam/.rvm/gems/ruby-1.9.3-p448#omega.ecoop/gems/ffi-1.0.11 (no problem)
I wanted to use command line only (rather than jewelrybox GUI) to learn some new skills along the way but fairly stuck here. Any help would be appreciated, thanks.
EDIT
So I tried a different approach, I thought maybe it was the version of ruby that was not compatible:
rvm install 2.0.0
then create gemset this time using ruby 2.0.0
rvm use 2.0.0#omega.ecoop --create
Check it's there and selected as the current gemset (ready to install some gems)
rvm gemset list
gemsets for ruby-2.0.0-p247 (found in /Users/Sam/.rvm/gems/ruby-2.0.0-p247)

Works fine for my project now. Not sure of any consequences of using a newer version of ruby but lost enough time already, need to do some designing. Obviously this wont help someone who needs 1.9.3 so that original query of why ffi wouldn't install is yet to be addressed.

Your .ruby-version file in that directory is still 1.9.3.
My two cents- well, tuppenny.
I encountered this issue whilst trying to install an Omega 4 subtheme in Drupal when running bundle install before step 11 (which isn't mentioned in the guide... sigh.)
Omega has loads of placeholders called {{ THEME }} which are meant to be replaced by your custom theme name- and somehow (forgive me as I know nothing about Ruby!) it tried to use this weird placeholder with spaces in the gemfile.
It also tried to save the gems to the folder /home/ubuntu/.rvm/gems/ruby-1.9.3-p547#omega.{{ THEME }}/gems, which I knew looked suss.
To resolve it I did the following:
rvm use 1.9.3-p547#omega.subthemename --create
rvm gemset list
gemsets for ruby-1.9.3-p547 (found in /home/ubuntu/.rvm/gems/ruby-1.9.3-p547)
(default)
global
=> omega.mysubtheme
omega.{{ THEME }}
bundle install # This now works!
Hope this helps someone! The conclusion is that this is usually a problem with filename spaces somewhere- a lot of people have issues with OSX because it resolves the path to "Macintosh HD" which is an invalid name.
You need to make sure you have gcc46 installed.
Try brew install gcc46 and then re-run bundle install.
Usually when I have this issue it the solution is to make sure Xcode is updated.

Is it a known bug? or am i doing something wrong?
For Ruby 2.0.0-p0, I also get similar warnings from gem check. However, I don't have issues at runtime with any of these gems. I suspect this might be a bug with Rubygems check command in 2.0.0.
I have similar errors. Passing options to compiler fix installation.
Before install readline and openssl with Homebrew.

Can't remove execjs gem

I am using Ruby and I am having trouble removing a gem. The gem is execjs. Here is some background information.
rvm use #global
rvm gem list
Outputs...
*** LOCAL GEMS ***
...
execjs (1.2.9)
...
Running either of the following commands
rvm gem uninstall execjs
OR
rvm gem uninstall execjs -v 1.2.9
outputs this
INFO: gem "execjs" is not installed
So it showed the gem in the gem list, but when I go to uninstall it, it says that it isn't there. I'm confused ?
You should use this command for remove any gem
gem uninstall execjs -v=1.2.9
Hope it will work.
