Error while launching knife configure command - ruby

I tried to getting started with chef so I installed the chef gem on my laptop ( OS : OSX 10.8) with ruby 2.0.0-p0 but when I try to "knife configure " I juste get this message :

The accepted answer isn't entirely correct. The problem isn't ruby 2.0, it's rubygems 2.x. If you run gem update --system 1.8.25 to downgrade to a pre 2.x rubygems, everything works like a champ.
NOTE: I haven't had to do this locally, but this is how I've gotten knife bootstrap to work against my remote servers. I'm running ruby 2.0 on my local machine with latest rubygems and chef 11.4.4 and everything else seems to work properly.

According to this issue at opscode it was a bug. It has been fixed in chef 11.6.0.
The problem is that only chef 11.4.4 is on rubygems as of today (2013-06-23)
So, either use 1.9.x or rubygems 1.8.25 will work for now, until the next version of chef comes out. It may be possible to build it from https://github.com/opscode/chef.git
I ended up patching my chef 11.4.4 lib/chef/provider/package/rubygems.rb with this file: https://github.com/opscode/chef/blob/d6748efde62502ab6f5d97052f46ca00352497ef/lib/chef/provider/package/rubygems.rb

I had similar errors trying to use Chef (10.24 and 11.4) with Ruby 2.0 - so I assume Chef is not yet Ruby 2.0 compatible :(

The accepted answer is great if you're using the system ruby (/usr/bin/ruby, for example), but it didn't work for me because I'm using RVM. I found an equivalent solution in case you're using RVM:
rvm rubygems 1.8.25 will install rubygems version 1.8.25 for your RVM ruby.

my gemfile has gem 'mysql2', '~> 0.3.18'
windows 7
ruby version 2.2.1
rails 4.2.1
mySql server version 5.6.24
Edit:
Couldn't find a solution that worked for me so i installed a different version of rails and it worked out.
Make sure you have installed mysql2 gem using bundle install and that bundle install has returned successful installation.
#James, This issue has been already raised so follow these links and hope this may help you.
1) Error "...cannot load such file -- mysql2/2.0/mysql2 (LoadError)". On Windows XP with Ruby 2.0.0
2) Ruby on Rails - cannot load such file -- mysql2/2.2/mysql2 (LoadError)
3) https://github.com/bundler/bundler/issues/3456
Try to change
gem 'mysql2', '~> 0.3.18'
to
gem 'mysql2', '~> 0.3.11'
I think that maximum compatible version with Windows is 0.3.11. Then run again bundle install

Solution:
Do gem update --system. It appears that you hadn't installed an updated version of rubygems to go with your new version of Ruby.
Sorry I took so long to get to a solution that worked for you, it seems more obvious now. :)
Original Answer:
Have you made sure that the global (or possibly local, if you have one set) Ruby version is set correctly with rbenv? Have you tried doing rbenv rehash.
It looks like you're missing the Set module in the Ruby standard library for some reason- but since I believe it is part of the standard library and should be there unless your Ruby installation is somehow broken, it makes me wonder if the shims installed by rbenv might be pointing at the wrong place. rbenv rehash should fix that problem, I believe, if that is the cause.
Otherwise, is there any more information about your environment you can give? Such as the output of
rbenv local
rbenv global
rbenv versions
Also, how are you starting the rails console?
Are you doing rails console in your project's directory?
If you start irb and then do require 'set', does it work, or does it throw an error?

How I can get working rhc?
Updating net-ssh to 2.9.3.beta1, as cremno suggested in this comment, resolved my problem.
gem install net-ssh -v 2.9.3.beta1
Before that, I tried gem install net-ssh, but it didn't help.
I ran into this problem when I used the latest version of Ruby (currently 2.2.1) as stated on the OpenShift setup instructions. I fixed it by:
Installing Ruby 1.9.3
Re-running "gem install rhc"
After that, I was able to run "rhc setup" without any issue.
If you are running Windows 10 Pro x64, try installing Ruby 2.1.8 (x64) with Git Version 2.7.0. This will surely allow you to run rhc setup as it did happened with me. Earlier I had a problem running & installing latest version of Ruby 2.2.4 (x64) but when I downgraded to ruby version 2.1.8 (x64) I was able to run rhc setup and configure OpenShift client toolson Windows. See the image for Ruby version I'm using - ruby 2.1.8p440 (2015-12-16 revision 53160) [x64-mingw32]
Read here for getting started to OpenShift client tools on windows.
Use the RHC tested Ruby version instead of the latest. As of today it is 1.9.3-p194
Try using/installing a lower version of ruby after uninstalling the 2,2,0 because some windows version conflict with ruby version you are using. I tried 2.2.3 and then lowered to 2.2.0 and it worked for me.
I ran into this same error, and none of the solutions worked for me. In a last attempt, I installed the Ruby 1.9.3-p551 version and the rhc setup went smoothly. I use a Windows 10 machine.
I am running Windows 10 Pro x64. I installed Ruby 2.1.8 (x64) with Git Version 2.7.2. Rhc was installed successfully. However, "rhc snapshot save ..." command had problem with net-ssh. However, after restarting windows 10 the errors was gone.
Remember to try reboot your windows.

Try to remove the gem vpim with this command:
gem uninstall vpim
I've tried an installation and don't need this gem.
If you really need that gem edit the file
/usr/local/rvm/gems/ruby-2.1.1/gems/vpim-0.695/lib/vpim/vcard.rb
and place this in the first line:
# encoding: US-ASCII
The vpim gem mentioned in your stack trace is not a requirement of core Redmine. It seems you have a custom plugin which requires that gem and which is not compatible with newer Ruby versions (i.e. anything >= 1.9).
To solve this issue, you thus need to update or remove that custom plugin. Also, right now, it is probably a good idea to not use Ruby 2.1 but Ruby 2.0 as it seems that Redmine core (or more generally, Rails 3.2) still has other issues with Ruby 2.1.1.

cannot load Ruby gems for Chef

I'm trying to install Chef solo on a VPS. I've installed Ruby and ran the install command for the Chef gems, however, when I check the version of Chef, it says that it can't load the file. I'm following along with the Railscast on the topic http://railscasts.com/episodes/339-chef-solo-basics?view=asciicast, except that I also installed rbenv and Ruby 2.0.0 as a preliminary step.
Can you identify what the cause of this error is?

Chef 11 is the latest version of chef and is now packaged with an embedded copy of ruby. See the following documentation:
http://wiki.opscode.com/display/chef/Installing+Chef+Client+and+Chef+Solo
What version of rubygem are you using?
Try using rubygems 1.8.25
I think the original poster may have been running into a ruby-2.0/rubygems-2.0 issue like CHEF-3933 on chef 11.4.4 Those have been fixed by now. Chef 11.10.0 supports ruby-2.1 + rubygems-2.2
Gem installs are highly discouraged if there's an omnibus installer. The railscast is now very out of date. Installation should be done with:
curl -L https://www.opscode.com/chef/install.sh | bash -s
