How to install ruby compass on Mac OS 10.8.2 - ruby

I start gem update and it runs something like this :
Marios-MacBook-Pro:~ MarioVMtz$ gem update --system
Updating RubyGems
Updating rubygems-update
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions into the /Library/Ruby/Gems/1.8 directory.
I installed xcode rvm what else do I need to install ruby compass on Mac OS 10.8.2?

Run the command using sudo? sudo gem update --system should sort your immediate problem.

Ruby 2.3.0 gem pg version 0.18.4 install error El Capitan

After "bundle install", I keep getting this error for many times.
Errno::EACCES: Permission denied # rb_sysopen - /Users/daisukeishii/tasca- io/vendor/bundle/ruby/2.3.0/gems/pg-0.18.4/.gemtest
An error occurred while installing pg (0.18.4), and Bundler cannot continue.
Make sure that `gem install pg -v '0.18.4'` succeeds before bundling.
gem install pg keeps giving the same error
-ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin15]
-psql (PostgreSQL) 9.5.0
-Mac El Capitan
-I checked all related posts in stackoverflow but could not solve this.
Tried to uninstall/install PostgreSQL through brew.
Tried to uninstall/install Ruby
Do you have any idea to solve this?
I had problems installing the pg gem and for me this did the trick:
ARCHFLAGS="-arch x86_64" gem install pg
However, looking at your error message it actually seems to be about not having write permissions to the gem directory. Maybe you have tried to install the gem as root with sudo gem install pg and it left behind a directory under your home directory having root as owner instead of your regular user.
Remove the directory using:
sudo rm -rf /Users/daisukeishii/tascaio/vendor/bundle/ruby/2.3.0/gems/pg-0.18.4
And then try installing again using the ARCHFLAGS above.
Note that your post has some sort of copy paste problem in the path so the path in this example might not be correct.
In my case, the pg gem was looking for a PostgreSQL installation in the wrong place, so I runned
bundle config build.pg --with-pg-config=/usr/local/Cellar/postgresql/9.4.5/bin/pg_config
which was where my PostgreSQL installation actually was, and then
bundle install

Why do I get "ERROR: While executing gem ... (Gem::FilePermissionError)"?

I uninstalled RVM and re-installed using a single user installation using:
\curl -L https://get.rvm.io | bash -s stable
When I do bundle, it prompts for:
Enter your password to install the bundled RubyGems to your system:
I tried using the answer in "ERROR: While executing gem … (Gem::FilePermissionError)" which did not fix it.
Then, while trying to install the gem manually, I got:
Gem::InstallError: nokogiri requires Ruby version >= 1.9.2.
An error occurred while installing nokogiri (1.6.0), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.0'` succeeds before bundling.
then running gem install nokogiri -v '1.6.0' returned:
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions into the /Library/Ruby/Gems/1.8 directory.
I checked all the similar posts on SO, but they didn't solve the problem. What am I missing?
I spent a lot of time fixing this issue on my MacBook. The gem update --system does not work for me.
At last, putting the following code in the ~/.zshrc file and create a new zsh session works for me.
export GEM_HOME="$HOME/.gem"
export GEM_PATH="$HOME/.gem"
after you install RVM you still need few more steps:
Load RVM to the current shell:
source ~/.rvm/scripts/rvm
Usually this would not be needed if you close and open your terminal again
Install ruby:
rvm install ruby
Use ruby:
rvm use ruby
The last step is very important as your error message mentioned system ruby not the one controlled by RVM.
Make sure to update your system rubygems with this command : sudo gem update --system --no-user-install.
bundler use it instead your local version and your bundler version could be incompatible with your system rubygems.
It works for me ;)

dev_appserver.rb cannot start after rubygems update on Ubuntu 10.04

I had rubygems 1.3.5 (or 1.3.6?) installed and then made a sudo gem update after a long while again. Some gems complained they needed a newer gems version. Because sudo gem update --system is deactivated on Ubuntu I followed these steps: How can I get RubyGems 1.3.6 on Ubuntu 10.4
But now I cannot start the dev_appserver.rb anymore, it says:
=> Bundling gems
ERROR: While executing gem ... (RuntimeError)
Unknown command bundle
I also tried to do sudo gem update and sudo gem update --system again a few times but everything is up-to-date now. Here is a list of my gems: http://pastebin.com/cFaTCyF5
It's a bit of a hack around but I can't really tell what's going on properly from what you sent but I know a few people have been having problems after running gem update --system lately. Find out what version you've just installed with
gem list
Look for the update, should look something like this: rubygems-update-1.5.0
Then try rolling back your rubygems version
sudo gem uninstall rubygems-update -v 1.5.0
sudo gem install rubygems-update -v 1.4.2 <-- try a different version
gem install --system 1.3.7 worked in my case

How do you install Jekyll on OSX?

I was following the instructions here, so I ran gem install jekyll on my osx machine, and got the following:
WARNING: Installing to ~/.gem since /Library/Ruby/Gems/1.8 and
/usr/bin aren't both writable.
WARNING: You don't have /Users/erikvold/.gem/ruby/1.8/bin in your PATH,
gem executables will not run.
ERROR: Error installing jekyll:
liquid requires RubyGems version >= 1.3.7
But I don't see instructions on how to deal with this in the instructions above.
Try to update gem first:
$ gem update --system
In case you get permission errors, you must resort to sudo for this and all other gem commands:
$ sudo gem update --system

Cannot upgrade RubyGems 1.2

Why is the following happening, and how can I sort it?
On OS X Leopard (v10.5.6):
$ ./script/server
Rails requires RubyGems >= 1.3.1 (you have 1.2.0). Please `gem update --system` and try again.
$ sudo gem update --system
Updating RubyGems
Nothing to update
I haven't hit this issue myself but I've seen this as a possible solution:
$ sudo gem install rubygems-update
Successfully installed rubygems-update-1.3.0
1 gem installed
$ sudo update_rubygems
This should let you install the updating via the specific updater gem.
