I am trying to install RmMagic using the below command:
gem install rmagick -v=2.12.2
After running this command i get some error :
Temporarily enhancing PATH to include DevKit...

Please help me in this regard. Thanks in advance.
I had same problem with rmagick to solve this add System Environment Variable
CLASSPATH .;C:\ImageMagick-6.5.6-Q8\include
lib C:\ImageMagick-6.5.6-Q8\lib
Then do
gem install rmagick --platform=ruby -- --with-opt-lib=C:\ImageMagick-6.5.6-Q8\lib --with-opt-include=C:\ImageMagick-6.5.6-Q8\include
What a pain this was... I definitely needed to do both the System Environment Variables AND the specific syntax of the command as suggested by Mukesh
To clarify the two steps:(for other novices like me)
Click properties from context menu of "Computer, click "Advanced System Settings",
click "Environment Variables", click "New" under System Variables,
use CLASSPATH for the variable name and for the value use:
.;C:\ImageMagick-6.9.0-Q16\include;lib C:\ImageMagick-6.9.0-Q16\lib
Then Run As Administrator the Command Prompt with Ruby terminal and execute:
gem install rmagick -v '2.13.4' -- --with-opt-lib=C:\ImageMagick-6.9.0-Q16\lib --with-opt-include=C:\ImageMagick-6.9.0-Q16\include
(***Make sure to update the versions number in both the Variable and gem command if necessary)

Please assist solving this problem
I am new to python and know nothing about ruby, but I find ipython notebook so amazing that I want give it a try for another kernel,
so I just installed ruby and end up with the same problem, and google failed to help me，，，
but I am really good at patching things, after one hour of ##$#%&%#%!(#!, I found a way:
edit C:\Ruby22-x64\lib\ruby\gems\2.2.0\gems\rbczmq-1.7.9\ext\rbczmq\extconf.rb
add statement GNU_CHAIN = 1 on the top
cd C:\Ruby22-x64\lib\ruby\gems\2.2.0\gems\rbczmq-1.7.9
gem spec ....\cache\rbczmq-1.7.9.gem --ruby > ....\specifications\rbczmq-1.7.9.gem.gemspec
gem build ....\specifications\rbczmq-1.7.9.gem.gemspec
now, gem list shows "rbczmq (1.7.9)"
I knew nothing about ruby, so I dont know whether rbczmq really works or not
"iruby notebook" starts succ and new kernel "ruby 2.2.2" added, but it also says "kernel error" when I choose it
the Track back says: "OSError: [WinError 193]"
That's all I can help for now, so maybe you can figure it out now and tell me how to make the new kernel do its trick
I am getting this error

You need to install libossp-uuid and it's dev headers.
Probably something like:
sudo apt-get install libossp-uuid-dev
And then the gem installs.
Are you sure you need to use that gem anyway? In ruby 1.9+ there's already the module SecureRandom in standard library which provides UUID and also lots of pure ruby gems like uuidtools and uuid. If you need to parse the UUID's, there's ruby-uuid.
If you're running OS X Yosemite do the following:
gem install uuid
brew install ossp-uuid
(You need to have brew already installed. If you don't you can get it from here: http://brew.sh)
If you're using rvm, check that your session state is correct. If you cd around a lot, reset your terminal, or your environment variables get corrupted, you can end up with your commands trying to work with the system Ruby. A quick way to reset rvm-related stuff is just doing cd . in a project directory.
$ cd .
$ gem install uuid
Originally posted here: "How to use the debugger with Ruby 2.0?"
I keep ending up back here, but I have a different problem. I don't have the option to change to Byebug right now. We are currently stuck on "debugger" for now, and I cannot install it.

Anyone have any ideas?
Update: Now Ruby 2.1+ should using byebug instead of debugger.
clone the debugger-ruby_core_source to local folder, e.g. C:\git\debugger-ruby_core_source
copy C:\git\debugger-ruby_core_source\lib to C:\Ruby200\lib\ruby\gems\2.0.0\gems\debugger-ruby_core_source-1.3.2
run the gem install debugger again.
I'm now sure why the gems debugger-ruby_core_source didn't copy the lib to that folder, but certainly the debugger need it.
I am trying to install the Stanford-Core-NLP gem, which is one of the major projects on github for natural language processing using Ruby. It provides Ruby bindings for the Stanford-Core-NLP pakage, which where written in Java. When I try following the first step of the the installation instructions, which is:
gem install stanford-core-nlp
I get the following error:

extconf.rb:53:in `<main>': JAVA_HOME is not set. (RuntimeError)
I am running Ruby 1.9.2, which according to the repo, is the latest version the gem has been tested on and Java 1.7.0_40. I also tried looking for the mkmf.log file, but was unable to locate it.
This is because JAVA_HOME is getting reset in the sudo mode. To fix it, open your /etc/sudoers file add the following line and save it.
Defaults env_keep += "JAVA_HOME"
now reopen the terminal and install the gem.
I've been wrestling with this on Ubuntu. The thing that works reliably (though it is a sledgehammer) is:
JAVA_HOME=/usr/lib/whatever gem install stanford-core-nlp
The installation script is sensitive to the format of JAVA_HOME - it shouldn't end in a slash character.
I have been stuck on this for a couple of days now, so PLEASE help!

I have tried reinstalling RVM a couple of times and making some of the other changes recommended in similar questions.
My gem file compiles just fine without the opencv gem, but I am having similar issues with RMagick (showing an extconf.rb error).
What should I do?
Thanks!!!
In case anyone else experiences this, I had better similar problems on OS X and had better luck with the ruby-opencv gem.
