It also looks like someone forked ultraviolet and that the fork ( [GitHub - spox/ultraviolet: Updated version of the ultraviolet library for 1.9](http://github.com/spox/ultraviolet) ) is ruby 1.9 compatible which rather implies that the original isn’t. It doesn’t look like the fork has any native code dependencies (onigurama is a regular express library which has become the standard ruby one in ruby 1.9) Fred ---

Hi Frederick, I actually was able to install both ultraviolet and oniguruma with the following commands : gem install oniguruma --platform=mingw32 gem install ultraviolet --platform=mingw32 So know when I run gem list --local I see \*\*\* LOCAL GEMS \*\*\* actionmailer (2.3.5) actionpack (2.3.5) activerecord (2.3.5) activeresource (2.3.5) activesupport (2.3.5) git (1.2.5) hpricot (0.8.2) mysql (2.8.1) oniguruma (1.1.0) plist (3.1.0) rack (1.0.1) rails (2.3.5) rake (0.8.7) textpow (0.10.1) ultraviolet (0.10.2) But know I’m having a different problem running script/plugin install git://github.com/michaeledgar/harsh.git I always get Plugin not found: [“git://github.com/michaeledgar/harsh.git”] I get the same error with all the plugins I try to install, I also tried replacing git with http:// and adding a trailing slash at the end but with the same result. I also tried downloading the plugin manually and copying it to the vendor folder, but is not making the correct replacement and when I try to run the rake tasks from the plugin I get the following error output : rake harsh:theme:list (in O:/Personal/2010/allanmacgregor.com/RubyMineProjects/Snippy) C:/Ruby19/lib/ruby/gems/1.9.1/gems/oniguruma-1.1.0/lib/oniguruma.rb: 1:in `requir e': 126: The specified module could not be found. - C:/Ruby19/lib/ ruby/gems/1. 9.1/gems/oniguruma-1.1.0-x86-mswin32/win/oregexp.so (LoadError) from C:/Ruby19/lib/ruby/gems/1.9.1/gems/oniguruma-1.1.0/lib/ oniguruma.rb :1:in `\’ from C:/Ruby19/lib/ruby/gems/1.9.1/gems/textpow-0.10.1/lib/ textpow.rb:2: in `require' from C:/Ruby19/lib/ruby/gems/1.9.1/gems/textpow-0.10.1/lib/ textpow.rb:2: in `\’ from C:/Ruby19/lib/ruby/gems/1.9.1/gems/ultraviolet-0.10.2/lib/ uv.rb:2:i n `require' from C:/Ruby19/lib/ruby/gems/1.9.1/gems/ultraviolet-0.10.2/lib/ uv.rb:2:i n `\’ from C:/Ruby19/lib/ruby/gems/1.9.1/gems/ultraviolet-0.10.2/bin/ uv:8:in `require' from C:/Ruby19/lib/ruby/gems/1.9.1/gems/ultraviolet-0.10.2/bin/ uv:8:in` rescue in \’ from C:/Ruby19/lib/ruby/gems/1.9.1/gems/ultraviolet-0.10.2/bin/ uv:3:in `' from C:/Ruby19/bin/uv:19:in`load’ from C:/Ruby19/bin/uv:19:in `’ Any help getting this solved is highly appreciated Cheers!

Hi amacgregor, Any help would be greatly appreciated. Could you explain to me, perhaps with some detail, how you got the gem install oniguruma --platform–mingw32 to work? I installed the devkit for Ruby 19 on Windows. I’ve used it to successfully to get the RMagick gem working on 1.9 so it seems perfectly capable of doing it. I’m not sure what other steps I need to take for the oniguruma gem. I typed the command directly at the command prompt but got errors. I also typed the command in from the msys console. It gave me errors too. Do I need to download oniguruma in C or something first? Sorry, I have very little experience with this. Sunny
