Searching on the jetbrains website, I came up with this: https://www.jetbrains.com/ruby/help/configuring-ruby-sdk.html. However, I don't have the Ruby SDK pane. I have set the project to have the Project SDK for the version of Ruby installed, the Modules->Dependencies has the version of Ruby selected, but each time the project loads, it prompts me to set the framework to JRuby. It's not a JRuby project. Granted, I don't have RubyMine, but I thought that that was the purpose of Ultimate, to be an all-in-one.
Maybe a late response, but here's answer anyway. I stumbled upon the same issue while evaluating the Ultimate version.
To fix the "JRuby on Rails framework detected" issue, just create a new project "from existing sources". Follow the steps in the wizard and "Ruby on Rails" framework will be detected correctly - no more JRuby...
Hope it helps!

Well since you are on windows 7 you need to install ruby so follow this http://rubyinstaller.org/downloads/
Then go back to preferences and see if your sdks is there.
i downloaded the rails installer and tried to install, but i get the error in the screenshot. I have re-downloaded the file several times and installed times over, but without success.
what is the problem?
Can you please try with version 2.2.2? Additionally, any issues with the installer should be reported in Github Issues.

I have recently installed the Aptana plugin for Eclipse as I wish to learn Ruby and Ruby on Rails, it doesn't seem to have changed anything. Usually when I install a plugin of the sort, there will be new project types under the "New Project" menu, but none appeared. I checked tutorials online and they suggest that there should be new project types as seen in the image below, taken from a tutorial.
Instead, I see the same options I did before.
I wondered if the plugin didn't install, but when I try to install it again, It says it's already installed. I am using Eclipse Juno Service Release 2 with a 64-bit Windows 7 operating system and the version of the plugin from the URL given on the Aptana website (http://download.aptana.com/studio3/plugin/install). Any help would be much appreciated.
I don't know why that's happening. Here's a suggestion for how to get around it.
You might be better off installing and running the standalone Aptana Studio product. It would be a separate installation on your desktop, and thus wouldn't have the same settings as any Eclipse installation you already had, and would be more space on your hard drive. But probably there isn't much you would share between Ruby/Rails development and other development, and it's not that much space.
I've done it both ways - installed Aptana into an Eclipse I've already got, and installed the standalone version - and now I would only do standalone.
I don't know what was wrong in the first place, but after I installed the Aptana plugin, I installed the PyDev plugin. I think this removed the Aptana plugin because of conflicting dependencies (I don't know why it wouldn't tell me, though). I tried installing the Aptana plugin again and it told me there was a conflicting dependency with the PyDev plugin, so I uninstalled it and reinstalled the Aptana plugin. It works now.
I am new to the Linux scene and I am trying to get OpenCV installed and running on our server as I need it to build and run a few applications on the system. I have followed the Ubuntu package Install directions, but I seem to have an issue when I get to the install command. I get the terminal saying that it is reading the package list and after a few seconds I get a message saying that opencv cannot be found.
Has anyone had any experiences installing this library and can anyone possibly help guide me on how to use this whole setup? If it's any help I get a 404 error when I try to access the PPA in the update. Did I add the repository incorrectly?
Any advice is greatly appreciated.
OpenCV 2.1 is quite old. Try setting up his new PPA for OpenCV 2.3.1. It has a Natty target.
Hope that's helpful!
