Meet RubyMine 3.0 Beta with full Rails 3.0 support

Eugene Toporov

Please welcome a Beta version of the next major release of RubyMine IDE!

“3.0?” you may ask. That’s right!

Wile composing the list of what was done since RubyMine 2.0 we realized the delta is way bigger than 0.5. And with the main feature being Rails 3.0 support, RubyMine 3.0 sounds more logical!

Since the last EAP build we’ve added several small but nice improvements and compatibility fixes and baked a new build for you to try before the final release. View the list of changes in the Release Notes.

Download RubyMine 3.0 Beta.

Upd: RubyMine 3.0 will be a free upgrade if your license is purchased less than year ago. More info.

Develop with pleasure!

    I’ve just installed it. I see it looks quite differently, I’m looking forward to it 🙂

    but this means on the otherside if i have a 2.0 licence that i can at last use it for rails 3 at last i need to pay an upgrade price?

    Very nice, i can only agree with FX Poster.
    With the new beta, I have a significant performance boost on Ubuntu. Have you optimized the performance or is the impression misleading?

    Rails 3.0 support was in the roadmap at

    Like Arno.Nyhm says, a major release usually means an upgrade cost. I don’t mind paying this if it’s reasonable, but the roadmap was misleading at best and bait and switch at worst. Do you have any news on the upgrade cost? When I bought RubyMine earlier this year I had some concerns about Rails 3 support which the roadmap alleviated. This roadmap is now not to be followed?

    Hi Russel and Arno,
    if you bought license this year you’re eligible for this upgrade for free. Please read license agreement carefully:

    I am having some issues… I installed Rubymine 3.0, attached the lastest ruby version 1.9.2, with rails 3.0.1. Now I tried different version variations as well. But everytime I try I create a new project rake bugs out, saying :

    [rake –tasks] C:/Ruby192/lib/ruby/1.9.1/rubygems.rb:340:in `bin_path’: can’t find executable rake for rake-0.8.7 (Gem::Exception)
    from C:/Ruby192/bin/rake:19:in `’

    C:/Ruby192/lib/ruby/gems/1.9.1/gems/sqlite3-ruby-1.3.1-x86-mingw32/lib/sqlite3.rb:6:in `require’: no such file to load — sqlite3/sqlite3_native (LoadError)

    There were a lot of other errors as well, but the sqlite3/sqlite3_native seems to sum up the issue. I tried bundle install, along with attaching the gem individually, still no go. Any ideas? Email me at

    System: Windows 7 64bit

    what’s happened to the widen selection shortcut – i can’t find it in the keymap anywhere… is it a pebcak problem or has it disappeared?

    @Shaun, this is a problem with bundled 1.9.2 rake version. Please see

    Can’t use debug for 1.9.2 and Rails 3. Is there any documentation on how to get this working
